System, methods, and compositions are described for detecting and inhibiting leaks of a transmission system. The composition may include one or more transmission system sealants and one or more light activated compounds. The transmission system sealant(s) inhibit one or more of the leaks in the transmission system. One or more of the light activated compounds are visible when activating light is directed towards a portion of the exterior of the transmission system.

A combination pressure measurement/charging system may include a conduit coupled to a refrigerant can. The conduit may be coupled to a low-pressure side of a refrigerant system. The system may include a valve to control a flow of fluid through the conduit. Thus, a flow of fluid between the refrigerant can and the low-pressure side of the refrigerant system may be controlled using the valve. A first pressure gauge may be in fluid communication with the conduit. The first pressure gauge may be coupled to the low-pressure side of the refrigerant system. The first pressure gauge may be used to operate the valve to control fluid flow through the conduit. A second pressure gauge may be coupled to a high-pressure side of the refrigerant system. The second pressure gauge may be isolated from fluids that flow through the conduit.

A combination pressure measurement/refrigerant charging apparatus may include a shutoff valve that includes a piercing pin and a pressure gauge. The piercing pin may be used to pierce a refrigerant can. The pressure gauge may be used as a handle for operating the shutoff valve. A first end of a hose may be coupled to the shutoff. A quick coupling device may be coupled to a second end of the hose. The quick coupling device may be used to couple the apparatus to a refrigerant system.

Pressure testing and refrigerant recharging hose assembly for automobiles

A system and method for dispensing a pressurized fluid from a container into an automobile air conditioning system. A moveable plunger in an interior of a housing may engage an automobile air conditioning system valve and pressurized container valve to allow refrigerant and lubricant to flow from the pressurized container into the automobile air conditioning system. A quick-connect coupling may be used to couple the housing to the automobile air conditioning system after the housing has been snapped onto the pressurized container. In addition, the moveable plunger may be biased toward the automobile air conditioning system valve by a spring to ensure the automobile air conditioning system valve is opened when the housing is coupled to the automobile air conditioning system.

A supply canister is partially filled with a refrigerant circuit additive liquid and is partially evacuated. Additive liquid from the canister may be placed into the refrigerant circuit of an air conditioning system by (1) connecting the canister to the circuit after it has been emptied and a vacuum pressure created therein, (2) connecting the canister to the refrigerant circuit suction line during system operation, or (3) connecting the canister to the suction line with the system off, to thereby force refrigerant from the circuit into the canister, and then starting the system to cause the vacuum pressure in the suction line to draw the contents of the canister into the refrigerant circuit.

Apparatus and methods for placing an additive fluid into a refrigerant circuit

A refrigerant charging/pressure testing hose assembly meeting SAE standard J2196 is useable to both (1) check the pressure in a refrigerant circuit and, (2) if necessary, add refrigerant to the circuit. The assembly includes a length of refrigerant charging, hose having a quick disconnect coupler disposed at one end and connectable to a service fitting portion of the circuit, a piercing-type shutoff valve disposed at the other hose end and connectable to a refrigerant charging canister, a pressure gauge installed in a longitudinally intermediate portion of the hose, and a check valve installed in the hose between the shutoff valve and the pressure gauge and permitting flow through the hose only toward the quick coupler.

Apparatus methods and compositions for placing additive fluids into a refrigerant circuit

A refrigerant charging hose assembly has an aerosol shut-off valve connectable to a refrigerant canister and interconnected to a disconnect coupler fitting by a length of refrigerant charging hose, the body portion of the coupler fitting being economically formed from high tensile strength elastomeric plastic material. A spring-loaded, floatingly supported control pin member is shifted to open the disconnect coupler fitting when the pin member engages and depresses a corresponding pin member within an air conditioning system service fitting to which the coupler fitting is connected. when the coupler fitting is removed from the service fitting the coupler fitting pin member is spring-driven back to its original position in which a flange portion thereof closes the coupler fitting to prevent discharge of pressurized refrigerant therethrough from the canister.

An injection device is operable to force a treatment fluid into a refrigerant circuit having an R-134a service fitting thereon and includes a tubular container in which the treatment fluid is disposed. The container has an outlet structure with a body section adapted to sealingly receive and open the service fitting, and a rotatable nut portion operative to deform the body section and releasably lock it onto the service fitting. A hollow plunger member is threaded into the container and may be (1) threadingly advanced into the container to force the treatment fluid outwardly therefrom into the refrigerant circuit, or (2) serve as a conduit through which a pressurized driving fluid may be forced into the container to drive the treatment fluid into the refrigerant circuit. Inlet and outlet check valve structures are incorporated into the device to prevent undesirable fluid backflow therethrough. The inlet check valve structure includes an annular elastomeric sleeve member that has a flat cross-sectional shape around its periphery, circumscribes a tubular outlet portion of the plunger member, and functions to block side wall outlet openings therein in a manner preventing fluid backflow therethrough, while at the same time being fluid pressure-expandable in a radial direction to permit fluid flow through the outlet openings in the desired operative direction.

Refrigerant fluid injection apparatus

A compact device for sealingly storing, and subsequently delivering to the interior of a tire, a predetermined charge quantity of a tire leak sealant liquid includes a hollow liquid storage and transfer member, having an inlet fitting and an outlet fitting, within which the sealant liquid is disposed. When the hollow member is operatively interconnected between a pressurized air source and the tire's valve stem, pressurized air sequentially forces the entire sealant liquid charge volume into the tire and then flows into the tire through the storage and transfer member. Accordingly, the device may be utilized to repair and fully inflate a flat tire. A check valve structure incorporated in the device prevents fluid backflow through the storage and transfer member. The device may also be used to force other treatment liquids, such as a tire conditioner liquid, into the tire. In an alternate embodiment of the device, the storage and transfer member is filled with a refrigerant circuit treatment liquid and may be interconnected between a source of pressurized refrigerant and a refrigerant circuit fill valve to recharge the circuit and force the treatment liquid thereinto.
