In general, the present disclosure may relate to fluid containment and transfer systems.
A wide variety of power equipment is distributed and purchased in the marketplace. Often, where such power equipment is purchased can be geographically removed from where it is manufactured. For this reason, shipping, storing, distributing, displaying, and ultimately transferring ownership of the power equipment is required. In the case of power equipment utilizing internal combustion engines, or requiring lubricant that must be periodically replaced or replenished, it can be undesirable to ship, store, distribute, display, or transfer the power equipment having the necessary fluids (such as lubricants) already present in the power equipment. For example, during any of the handling or shipping from manufacture to transfer there is the possibility that the power equipment may be dropped or otherwise oriented in a manner that could allow the fluids to escape and cause potential health, safety, environmental, or other concerns. For this reason, the necessary fluids are often shipped in separate sealed containers, or required to be purchased separately. As such, it is necessary for the ultimate user of the power equipment (and/or an intervening party) to properly prepare the power equipment for use. However, in many instances such preparation may be relatively messy, or require additional tools, such as funnels, and the like, to perform proper set-up. Such additional tools and/or mess can often be undesirable for the ultimate user of the power equipment.
According to an implementation, a system for transferring fluid may include a container including an interior volume configured to hold a volume of fluid. The system may also include an adapter associated with the container for providing fluid communication with the volume of fluid. A receiver may be configured to be fluidly coupled with a reservoir. The receiver may be configured to releasably engage the adapter. The receiver may include a valve configured to be opened when the adapter is engaged with the receiver to allow fluid transfer between the container and the reservoir.
One or more of the following features may be included. The container may include one or more at least partially flexible walls. The container may include a generally rigid container. The adapter may be one or more of fixedly attached to the container and integrally formed with the container. The adapter may be removably coupled with the container.
One or more of the container and the adapter may include a seal configured to render the container generally fluid tight when the seal is in one or more of an intact condition and a sealed condition. The seal may be configured to be opened upon engagement of the adapter with the receiver to allow fluid communication between the container and the reservoir. The seal may include one or more of a foil and a membrane seal. The receiver may include a piercer configured to rupture the seal when the adapter is engaged with the receiver. The seal may include a re-sealable structure, the re-sealable structure may be configured to open upon engagement with the receiver and re-seal upon disengagement with the receiver.
The receiver may be configured to be removably coupled with the reservoir. The receiver and adapter may include cooperating twist-lock features for releasably engaging the receiver and the adapter. The valve of the receiver may include a check-valve configured to be opened when the adapter is engaged with the receiver and configured to be closed with the adapter is disengaged from the receiver. The volume of fluid may include engine oil, and the reservoir may include one of an engine oil reservoir and a pump lubricating oil reservoir.
According to another implementation, a method may include providing a container. The container may include an interior volume including a volume of fluid. The container may also include an adapter configured to provide fluid communication with the interior volume. The method may also include releasably engaging the adapter and a receiver that is in fluid communication with a reservoir. The method may further include transferring fluid between the container and the reservoir via the adapter and the receiver.
One or more of the following features may be included. Releasably engaging the adapter and the receiver may include releasably engaging cooperating twist-lock features associated with the adapter and the receiver.
One or more of the container and the adapter may include a seal preventing egress of the fluid from the interior volume. Releasably engaging the adapter with the receiving may include releasing the seal. The seal may include one of a foil member and a film member. Releasing the seal may include at least partially rupturing the seal by a piercer associated with the receiver. The receiver may include a check valve. Releasably engaging the adapter and the receiver may open the check valve to provide fluid communication with the reservoir.
The volume of fluid may include a volume of lubricating oil. The reservoir may include one or more of an engine oil reservoir and a lubricating oil reservoir of a pump. Transferring fluid between the container and the reservoir may include at least partially filling the reservoir with the lubricating oil.
According to yet another implementation, a fluid transfer system may include an adapter configured to be associated with a container including an interior volume configured for retaining a volume of fluid. The fluid transfer system may also include a receiver configured to be fluidly coupled with a fluid reservoir. The receiver may include a valve configured to be opened when the adapter is releasably engaged with the receiver to allow fluid transfer between the interior volume of the container and the fluid reservoir.
One or more of the following features may be included. The adapter may be one of permanently affixed and integrally formed with the container. The adapter may be configured to be removably coupled with the container. One or more of the adapter and the container may include a seal. The seal may be configured to be opened when the adapter is releasably engaged with the receiver to provide fluid communication with the interior volume of the container. The receiver may be one or more of removably coupleable to a fill port of the reservoir and integrated into a cap for the fill port of the reservoir.
In general, some embodiments of the present disclosure may provide a system for transferring a fluid between a container and a reservoir. In some embodiments, the container may be provided having an adapter that may releasably engage a receiver coupled to the reservoir. In some embodiments, the container may be sealed prior to being engaged with the receiver. Upon being engaged with the receiver, the seal of the container may be opened to allow fluid transfer between the container and the reservoir, via the receiver. Further, in some embodiments, the receiver may include a check valve arrangement. In some embodiments, the check valve may be in a closed position when the adapter is not engaged with the receiver. As such, the check valve may generally prevent ingress or egress to the reservoir via the receiver. The check valve may be opened when the adapter of the container is engaged with the receiver. In some embodiments, the engagement of the adapter with the receiver may cause the check valve to open, thereby allowing fluid transfer between the container and the reservoir via the receiver. Further, in some embodiment, disengagement of the adapter from the receiver may cause the check valve to close, thereby, again, preventing ingress or egress to the reservoir via the receiver. In some embodiments, the seal on the container may be opened by the engagement with the receiver. In some embodiments, the seal, once opened by engagement with the receiver may remain open, even after the adapter of the container is disengaged from the receiver. In some embodiments, the seal of the container may reseal when the adapter of the container is disengaged from the receiver, thereby once again rendering the container generally fluid tight (with respect to the seal of the container). In such an embodiment, the seal of the container may also be configured as a check valve.
In one particular illustrative example embodiment, a system consistent with the present disclosure may be utilized for transferring oil between a container and an oil reservoir of an engine (such as an engine crankcase), transferring oil between a container and an oil reservoir of a pump (e.g., which may be used for lubricating features of the pump during operation), transferring a cleaning solution between a container and a dispensing reservoir (such as a cleaning solution reservoir of a pressure washer or similar equipment). For example, commonly power equipment (e.g., pressure washers, generators, lawnmowers, snow blowers, etc.) are not shipped filled with oil as there may be a possibility of leakage during transport or storage. As such, upon initial usage of the power equipment it is necessary for the user to charge the power equipment with oil prior to use. Consistent with an illustrative example embodiment, the container may include a charge of oil (e.g., which in some embodiments may include a specific volume of oil corresponding to the desired volume of oil for the specific piece of associated power equipment). The container may be sealed in a generally fluid-tight condition, thereby rendering the container suitable for shipping, transporting, and/or storing with the piece of power equipment. Upon initial use or setup of the piece of power equipment, a receiver may be installed on (and/or may have previously been installed on, such as during manufacture or preparation for transport or sale) an oil fill port associated with the engine of the piece of power equipment, or other oil fill port (e.g., a fill port of an oil reservoir of a pump). With the receiver installed on the fill port, the adapter of the container may be engaged with the receiver, thereby allowing a predetermined, correct initial charge volume of oil to be transferred from the container to the oil reservoir of the engine or pump.
While the foregoing illustrative example embodiment relates to a system for providing a convenient arrangement for transferring an initial charge of oil from a container to an engine, it will be appreciated that the concepts consistent with the present disclosure may be utilized for a broad array of applications. For example, the container may include a volume of oil that is not selected to be a predetermined volume for use with a specific engine or pump (e.g., the container may include a nominal volume, such as one quart, etc.). Further, the system may be utilized for occasions other than providing an initial charge of oil (e.g., the system may be utilized in connection with routing maintenance oil changes). Further, and as indicated above, the system consistent with the present disclosure may be utilized for transferring any fluid from a container to a reservoir, and is not limited to transferring oil to an oil reservoir of a piece of power equipment. For example, the system may be utilized for charging a cleaning solution reservoir from a container, such as a cleaning solution reservoir for a pressure washer. Additionally, it will be appreciated that the system consistent with the present disclosure may be used in a variety of applications unrelated to power equipment.
Referring to
In various embodiments, the adapter may be fixedly attached to the container, and/or integrally formed with the container, and/or may be removeably coupled with the container. For example, as shown in
With particular reference to
While the illustrated example embodiment of
Referring to
As generally discussed above, in some embodiments the adapter 12 of the container 10 may be configured to be releasably coupled with the receiver 20. In the illustrated example embodiment, the adapter 12 may include features (e.g., protrusions 26, 28) to effectuate a twist-lock releasable coupling with the receiver 20. Correspondingly, the receiver 20 may include longitudinal slots (e.g., slots 30, 32) and circumferential grooves (e.g., groove 34 depicted in
In some embodiments consistent with the present disclosure, the receiver may include a check-valve configuration. The check-valve may be opened as a result of coupling the adapter with the receiver. When the adapter is not coupled with the receiver, the check-valve may be in a closed position. As such, when the adapter is not coupled with the receiver, and the receiver is in a closed position, the receiver may prevent, and/or reduce the likelihood of, foreign matter entering the reservoir through the fill port. For example, in implementations in which the receiver may be intended to be associate with an oil fill port of an engine or pump, it may be desirably to prevent, and/or reduce the occurrence of, the introduction of foreign material (e.g., dust, dirt, debris contaminants, moisture, etc.) into the oil reservoir, which may cause damage to the engine or pump, and/or otherwise be undesired. Additionally/alternatively, the check-valve configuration may prevent and/or reduce the extent and/or likelihood of oil spilling from the oil reservoir, e.g., if the engine or pump is tipped, etc.
With particular reference to
As generally described above, in some embodiments, the container 10 and/or the adapter 12 may include a seal, such as a membrane, that may be pierced, ruptured, and/or otherwise disrupted to allow fluid transfer with the container 10. Consistent with one such embodiment, the receiver 20 may include a piercer 40. Piercer 40 may be configured to pierce, or rupture, the seal 16 of the container 10 and/or the adapter 12. As generally shown, e.g., in
It will be appreciated that other check-valve arrangements may equally be utilized. For example, rather than the sliding member and the piercer being separate components, the sliding member may include a protrusion, e.g., which may facilitate puncturing or rupturing the seal of the container and/or adapter. Further, the sliding member may be configured to be displaced from an upper seat of the receiver (e.g., which may provide a generally fluid-tight arrangement in the closed position of the check-valve arrangement. The interior of the receiver may include an opening that is larger than the sliding member, e.g., to provide a fluid passage through the receiver around the sliding member. It will be appreciated that still further check-valve arrangements may also be utilized. Additionally, as described above, in some illustrative example embodiments, the adapter may include a check valve arrangement (e.g., rather than a rupturable seal). Consistent with some such arrangements, rather than rupturing a seal, the piercer of the receiver may serve to displace the sealing member away from the seat structure, against the biasing force of the biasing member, to thereby open the check valve of the adapter and/or of the container.
With reference to
As shown, releasably coupling the adapter 12 and the receiver 20 may further cause the adapter (e.g., distal end 44) to contact the sliding member 36, and slidingly displace the sliding member 36 from sealing contact with the enlarged distal portion of the piercer 40, e.g., to move the check-valve arrangement to the open position. Slidingly displacing the sliding member 16 may, accordingly, additionally expose the fluid passage formed between the proximal portion of the piercer 30 and the opening in the upper surface of the sliding member 36. Further, releasably coupling the adapter 12 and the receiver 20 may cause the piercer 40 to penetrate the seal 16 of the container 10 and/or the adapter 12. Accordingly, the penetration of the seal 16 and the sliding displacement of the sliding member 36 (i.e., moving the check-valve arrangement to the open position) may open the container 10 and the receiver 20 for fluid transfer therebetween.
Consistent with the present disclosure, the fluid transfer system may be utilized in a variety of implementations. For example, as generally discussed above, the fluid transfer system may allow an appropriate initial charge of oil to be shipped and/or sold with an engine (e.g., a piece of power equipment including an engine), a pump, or other device. The fluid transfer system may allow the initial charge of oil to be transferred during initial setup/operation of the engine or pump, e.g., with reduced likelihood of spillage and with improved convenience. Similarly, a fluid transfer system consistent with the present disclosure may facilitate charging the engine or pump with oil during routine maintenance. In this regard, the receiver may be installed on the oil fill port as part of the maintenance procedure (e.g., replacing the typical plug or cap), and may be removed after the maintenance has been conducted. Additionally/alternatively, the receiver may be utilized as the plug or cap for the oil fill port, and may be left in place during operation of the engine or pump. Further, in some embodiments, the fluid transfer system may be utilized to collect oil drained from an engine or pump. For example, the receiver may be installed on the fill port, and with the container and adapter releasably coupled with the receiver, the engine or pump may be tipped and/or oriented to allow the oil from the engine or pump to be drained into, and collected by, the container. In a similar manner, in which the engine or pump include an oil drain plug, the receiver may be installed in place of the oil drain plug, and may be used to collect oil from the engine or pump by releasably coupling the container and adapter to the receiver. In some embodiments, the receiver may be provided with an engine or pump. In some such embodiments, the container (e.g., including a charge of oil) and the adapter may also be provided with the engine or pump (e.g., for initially charging the engine or pump with oil). Further, in some embodiments, the container (alone or in combination with the adapter) may be obtained and used, e.g., for subsequent oil changes. In some such embodiments, the container may be provided alone and the adapter may be a reusable component (e.g., by being releasably coupled with the newly acquired container). In still further embodiments, the receiver and adapter (alone and/or with the container) may be obtained as a kit, and may be used for conducting maintenance on an engine or pump. Further, containers of oil (or other fluid, either alone or with an adapter) may be separately obtained, e.g., for use with the receiver (and, in some instances, re-use of a previously obtained adapter) during maintenance. In some of the foregoing example embodiments, the receiver may be utilized in place of the typical reservoir plug or cap, e.g., as a conversion installation to allow fluid transfer using a container and adapter.
While the foregoing description has been provided in the context of effecting oil transfer with an engine or pump, it will be appreciated that embodiments consistent with the present disclosure may be utilized for any suitable fluid transfers. For example, the embodiments consistent with the present disclosure may be used for filling (or draining) cleaning solution reservoir, a hydraulic system, coolant systems, and/or any other fluid systems in which it may be desirable to simplify the fluid transfer, reduce the likelihood, and/or extent, of spillage, and/or to provide an automatic closure of a fluid fill and/or drain port.
While various illustrative example embodiments have been described herein, including particular features and combinations of features, it will be appreciated that implementations may be provided consistent with the present disclosure that incorporate various combinations of elements and features described across the various illustrative example embodiments, and/or that may incorporate additional and/or alternative elements and features and/or combinations of elements and features. As such the described illustrative example embodiments should be understood as describing possible features, objectives, and advantages of the present disclosure, and are intended for illustrative purposes only. Further, the elements, features, and concepts of the present disclosure are susceptible to modification and variation, as will be appreciated by those having skill in the art. As such, the scope of the present invention should not be construed as limited to any of the described embodiments.
