Patent Application
20180112810
The following includes information that may be useful in understanding the present disclosure. It is not an admission that any of the information provided herein is prior art nor material to the presently described or claimed inventions, nor that any publication or document that is specifically or implicitly referenced is prior art.
The present invention relates generally to the field of pipe joints or couplings and more specifically relates to cap closures.
Over time, a vehicle's air conditioning valve core can become damaged and leak Freon. Unfortunately, the coolant is toxic if absorbed into the ground or ingested by animals, causing widespread pollution and illness. Freon is a gas, and may damage the environment by depleting the ozone layer. Additionally, it can be expensive for drivers to not only replace the leaking coolant/Freon but also repair the damaged air conditioning.
U.S. Pat. No. 9,180,755 to Ronie Dale Durall relates to a service port adapter device. The described service port adapter device includes an adapter device with a PTFE gasket that stops vehicle air conditioning system leaks on most R134a refrigerant non-serviceable air conditioning hoses. The adapter device makes the hose serviceable by replacing the damage non-serviceable service port with a new serviceable service port and valve.
In view of the foregoing disadvantages inherent in the known pipe joints or couplings art, the present disclosure provides a novel leak prevention device and method. The general purpose of the present disclosure, which will be described subsequently in greater detail, is to provide a quick connection and securing system for a vehicle air conditioning high and low intake valve stem. The leak prevention device may be designed for tool-less installations. Once installed, the system may effectively eliminate air conditioning leaks by maintaining pressure in the valve stem of the air conditioning line which stops the most common type of leak, and in turn saves money by preventing coolant leaks into the atmosphere making the system environmentally friendly.
A device for preventing leaks is disclosed herein. The device for preventing leaks includes a cylindrical body that may have a top end and a bottom end, a spring being biased within a hollow portion of the cylindrical body, a plurality of ball bearings located on an inner lower portion of the cylindrical body, a plurality of O-rings being removably located within the hollow portion of the cylindrical body, a sleeve being movably coupled to the cylindrical body. As such the device may be configured to prevent leakage from a pressurized valve.
For purposes of summarizing the invention, certain aspects, advantages, and novel features of the invention have been described herein. It is to be understood that not necessarily all such advantages may be achieved in accordance with any one particular embodiment of the invention. Thus, the invention may be embodied or carried out in a manner that achieves or optimizes one advantage or group of advantages as taught herein without necessarily achieving other advantages as may be taught or suggested herein. The features of the invention which are believed to be novel are particularly pointed out and distinctly claimed in the concluding portion of the specification. These and other features, aspects, and advantages of the present invention will become better understood with reference to the following drawings and detailed description.
The figures which accompany the written portion of this specification illustrate embodiments for the present disclosure, a leak prevention device, constructed and operative according to the teachings of the present disclosure.
The various embodiments of the present invention will hereinafter be described in conjunction with the appended drawings, wherein like designations denote like elements.
As discussed above, embodiments of the present disclosure relate to pipe joints or couplings and more particularly to a leak prevention device to minimize negative environmental impact.
Generally, the leak prevention device stops a leak from the air conditioning fittings where the Freon is recharged. This replaces the little plastic caps that do not hold pressure at all, and allows the Freon to leak to the environment.
Referring now more specifically to the drawings by numerals of reference, there is shown in
The embodiments of the invention described herein are exemplary and numerous modifications, variations and rearrangements can be readily envisioned to achieve substantially equivalent results, all of which are intended to be embraced within the spirit and scope of the invention. Further, the purpose of the foregoing abstract is to enable the U.S. Patent and Trademark Office and the public generally, and especially the scientist, engineers and practitioners in the art who are not familiar with patent or legal terms or phraseology, to determine quickly from a cursory inspection the nature and essence of the technical disclosure of the application.
The present application is related to and claims priority to U.S. Provisional Patent Application No. 62/412,845 filed Oct. 26, 2016, which is incorporated by reference herein in its entirety.
