The disclosure relates to a fluid valve system, and more particularly to a fluid valve system having a flow control assembly which optimizes performance.
Vehicle heat exchanges, such as radiators, have valves which are used to control the rate that a fluid such as coolant, for example, is allowed to flow through the system. With the increase in government mandated fuel economy regulations, companies are increasingly looking for new technology that will reduce the parasitic losses and improve efficiency of internal combustion engines. Furthermore, the introduction of hybrid and fully electric vehicle powertrains has introduced powertrain and thermal management complexities due to the need to control the temperature of batteries, inverter electronics, electric motors, etc. These trends lead to the need for more intelligently controlled fluid valve systems.
Conventional valve systems include diverter balls, cylinders, and the like to enable the heat exchangers to receive various intake and exhaust flows. As such, a single heat exchanger may function as a charge air cooler (CAC), exhaust gas recirculation (EGR) cooler, and heat recovery device. While these designs may provide adequate performance for proportional flow applications, they do have some drawbacks. For example, some conventional valve systems have a vertical inlet at a base of a diverter valve. This allows for a wider outlet to provide smooth blending of flow between two horizontal outlets positioned 90 degrees radially apart. With the vertical inlet, the inlet will not take up space on an outer diameter on a cylinder needed for the wider outlet and the inlet can remain in a stable position since it is located on a rotational axis of the cylinder. However, the vertical inlet on the cylinder typically requires a vertical inlet on a port housing of the valve system. The vertical inlet on the port housing, and fluid connections to that vertical inlet, consume valuable packaging space in a vehicle in relation to all of the other vehicle components mounted around the valve system.
Accordingly, it would be desirable to produce a fluid valve system wherein a size, weight, cost, and complexity thereof is minimized, while optimizing a performance thereof.
In concordance and agreement with the presently described subject matter, a fluid valve system wherein a size, weight, cost, and complexity thereof is minimized, while optimizing a performance thereof, have surprisingly been discovered.

Further areas of applicability will become apparent from the description provided herein. The description and specific examples in this summary are intended for purposes of illustration only and are not intended to limit the scope of the present disclosure.
The drawings described herein are for illustrative purposes only of selected embodiments and not all possible implementations, and are not intended to limit the scope of the present disclosure.
The following description of technology is merely exemplary in nature of the subject matter, manufacture and use of one or more inventions, and is not intended to limit the scope, application, or uses of any specific invention claimed in this application or in such other applications as may be filed claiming priority to this application, or patents issuing therefrom. Regarding methods disclosed, the order of the steps presented is exemplary in nature, and thus, the order of the steps can be different in various embodiments. “A” and “an” as used herein indicate “at least one” of the item is present; a plurality of such items may be present, when possible. Except where otherwise expressly indicated, all numerical quantities in this description are to be understood as modified by the word “about” and all geometric and spatial descriptors are to be understood as modified by the word “substantially” in describing the broadest scope of the technology. “About” when applied to numerical values indicates that the calculation or the measurement allows some slight imprecision in the value (with some approach to exactness in the value; approximately or reasonably close to the value; nearly). If, for some reason, the imprecision provided by “about” and/or “substantially” is not otherwise understood in the art with this ordinary meaning, then “about” and/or “substantially” as used herein indicates at least variations that may arise from ordinary methods of measuring or using such parameters.
All documents, including patents, patent applications, and scientific literature cited in this detailed description are incorporated herein by reference, unless otherwise expressly indicated. Where any conflict or ambiguity may exist between a document incorporated by reference and this detailed description, the present detailed description controls.
Although the open-ended term “comprising,” as a synonym of non-restrictive terms such as including, containing, or having, is used herein to describe and claim embodiments of the present technology, embodiments may alternatively be described using more limiting terms such as “consisting of” or “consisting essentially of.” Thus, for any given embodiment reciting materials, components, or process steps, the present technology also specifically includes embodiments consisting of, or consisting essentially of, such materials, components, or process steps excluding additional materials, components or processes (for consisting of) and excluding additional materials, components or processes affecting the significant properties of the embodiment (for consisting essentially of), even though such additional materials, components or processes are not explicitly recited in this application. For example, recitation of a composition or process reciting elements A, B and C specifically envisions embodiments consisting of, and consisting essentially of, A, B and C, excluding an element D that may be recited in the art, even though element D is not explicitly described as being excluded herein.
As referred to herein, all compositional percentages are by weight of the total composition, unless otherwise specified. Disclosures of ranges are, unless specified otherwise, inclusive of endpoints and include all distinct values and further divided ranges within the entire range. Thus, for example, a range of “from A to B” or “from about A to about B” is inclusive of A and of B. Disclosure of values and ranges of values for specific parameters (such as amounts, weight percentages, etc.) are not exclusive of other values and ranges of values useful herein. It is envisioned that two or more specific exemplified values for a given parameter may define endpoints for a range of values that may be claimed for the parameter. For example, if Parameter X is exemplified herein to have value A and also exemplified to have value Z, it is envisioned that Parameter X may have a range of values from about A to about Z. Similarly, it is envisioned that disclosure of two or more ranges of values for a parameter (whether such ranges are nested, overlapping or distinct) subsume all possible combination of ranges for the value that might be claimed using endpoints of the disclosed ranges. For example, if Parameter X is exemplified herein to have values in the range of 1-10, or 2-9, or 3-8, it is also envisioned that Parameter X may have other ranges of values including 1-9, 1-8, 1-3, 1-2, 2-10, 2-8, 2-3, 3-10, 3-9, and so on.
When an element or layer is referred to as being “on,” “engaged to,” “connected to,” or “coupled to” another element or layer, it may be directly on, engaged, connected or coupled to the other element or layer, or intervening elements or layers may be present. In contrast, when an element is referred to as being “directly on,” “directly engaged to,” “directly connected to” or “directly coupled to” another element or layer, there may be no intervening elements or layers present. Other words used to describe the relationship between elements should be interpreted in a like fashion (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.
Although the terms first, second, third, etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms may be only used to distinguish one element, component, region, layer or section from another region, layer or section. Terms such as “first,” “second,” and other numerical terms when used herein do not imply a sequence or order unless clearly indicated by the context. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the example embodiments.
Spatially relative terms, such as “inner,” “outer,” “beneath,” “below,” “lower,” “above,” “upper,” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. Spatially relative terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the example term “below” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
At least one driven element 13 (e.g., a driven gear, a pinion, etc.) and at least one positioning element 14 may be formed on the main body 12. As shown in
In some embodiments, the main body 12 has at least one passageway 15 formed therein. The passageway 15 may include at least one fluid inlet 16, shown in
In some embodiments, the passageway 15 may have an hourglass shape. A portion 20 of the passageway 15 between the fluid inlet 16 and the fluid outlet 18 may also be narrowed, wherein a cross-sectional area of the portion 20 may be smaller than the cross-sectional area of the fluid inlet 16 and/or the fluid outlet 18. Accordingly, a cross-sectional area of the passageway 15 varies from the fluid inlet 16 to the fluid outlet 18. It is understood, however, that in other embodiments, the cross-sectional area of the passageway 15 may be generally constant from the fluid inlet 16 to the fluid outlet 18.
Referring now to
In certain embodiments, the fluid valve system 100 may comprise a housing 102. As shown, the housing 102 may include at least one fluid inlet port 106 and a plurality of fluid outlet ports 108. The at least one fluid inlet port 106 may be in fluid communication with the at least one fluid source and each of the fluid outlet ports 108 may be in fluid communication with the at least one fluid destination. It is understood that the housing 102 may include more or less fluid inlet ports 106 and fluid outlet ports 108 than shown, if desired. It is further understood that each of the fluid inlet ports 106 may be in fluid communication with the same fluid source or separate and distinct fluid sources and each of the fluid outlet ports 108 may be in fluid communication with the same fluid destination or separate and distinct fluid destinations.
In some embodiments, one of the fluid outlet ports 108 and at least one of the at least one fluid inlet port 106 and another one of the fluid outlet ports 108 may lie on the same or a substantially similar plane (e.g., a horizontal plane, a transverse plane of the fluid valve system 100, etc.). As a result, the flow of the fluid from the at least one fluid inlet port 106, into and through the flow control member 10, may be substantially parallel to the flow of the fluid from the flow control member 10 into the fluid outlet ports 108, as depicted in
In exemplary embodiments, the housing 102 may include the fluid inlet port 106 for receiving a fluid from a fluid source, a first fluid outlet port 108a for distributing the fluid to a first fluid destination, and a second fluid outlet port 108b for distributing the fluid to a second fluid destination. In one embodiment, the fluid outlet port 108a and the fluid outlet port 108b may lie on the same or a substantially similar plane (e.g., a horizontal plane, a transverse plane of the fluid valve system 100, etc.). In another embodiment, the fluid inlet port 106 and one of the fluid outlet ports 108a, 108b may lie on the same or a substantially similar plane (e.g., a horizontal plane, a transverse plane of the fluid valve system 100, etc.). In yet another embodiment, the fluid inlet port 106 and both of the fluid outlet ports 108a, 108b may lie on the same or a substantially similar plane (e.g., a horizontal plane, a transverse plane of the fluid valve system 100, etc.). As such, a size (e.g., a vertical packaging profile), weight, cost, and complexity of the fluid valve system 100 is minimized and a direct flow of the fluid through the fluid valve system 100 is permitted to minimize a pressure loss through the fluid valve system 100 and optimize a performance thereof.
In some embodiments, the fluid outlet port 108a may be formed on the housing 102 relative to the fluid outlet port 108b formed on the housing 102 at an angle α of less than about 90 degrees. Particularly, the fluid outlet port 108a may be formed on the housing 102 relative to the fluid outlet port 108b formed on the housing 102 at an angle α in a range of about 40 degrees to about 80 degrees, and more preferably in a range of about 60 degrees to about 75 degrees. In a preferred embodiment, the fluid outlet port 108a may be formed on the housing 102 relative to the fluid outlet port 108b formed on the housing 102 at an angle of about 72 degrees. Such angle α between the fluid outlet ports 108a, 108b reduces the rotational movement of the flow control member 10 needed to travel therebetween. Additionally, the angle α between the fluid outlet ports 108a, 108b reduces a directional change for the flow of fluid from the at least one fluid inlet port 106 to the fluid outlet ports 108a, 108b, which further minimizes the pressure loss through the fluid valve system 100 and optimizes the performance thereof.
As illustrated in
The flow control member 10 may be selectively positionable within the housing 102 of the fluid valve system 100 and configured to selectively control the flow of the fluid therethrough. A first flow path comprising the at least one fluid inlet port 106 of the housing 102, the passageway 15 of the flow control member 10, and one of the fluid outlet ports 108 of the housing 102 is formed when the flow control member 10 is in the a first position as shown in
In a preferred embodiment, the flow control member 10 may be shaped and sized to cover an entirety of the aperture 122 while simultaneously leaving an entirety of the apertures 118, 120 uncovered when in the first position (depicted in
In other embodiments, the flow control member 10 may also be oriented in a fourth position (depicted in
One or more sealing elements 124 (e.g. O-rings, gaskets, elastomeric seals, and the like), shown in
In a second operating mode shown in
In a third operating mode shown in
In some embodiments, the fluid valve system 100 may further include the driving element or actuator. The driving element or actuator may be drivingly coupled to the driven element 13 to cause a rotational movement of the flow control member 10. The driving element or actuator may cause a rotational movement of the flow control member 10 in a first rotational direction (e.g. clockwise) and an opposite second rotational direction (e.g. counter-clockwise). More preferably, the driving element or actuator may cause the rotational movement of the flow control member 10 in the first rotational direction from the first position to the second position, and in the second rotational direction from the second position to the first position. The driving element or actuator may be powered by any electric motor with an ability to generate rotary motion. For example, the driving element or actuator may be driven by a stepper motor or a brushless DC (BLDC) motor. It is understood that other methods of actuation and causing the rotational movement of the flow control member 10 within the fluid valve system 100 may be used.
