Abstract: The closed loop oil service system operates in conjunction with an air conditioner or refrigerant compressor lubricated by lubricating oil contained within the compressor casing. The compressor includes a submerged oil drain port, submerged oil view port, a refrigerant inlet port and refrigerant outlet port. The closed loop oil service system utilizes a canister containing compressor lubricating oil and having a long stem first valve and a short stem second valve. The system also includes a pair of coupler hoses which fluidly and gaseously connect the canister valves and compressor ports. The first coupler hose is connected between compressor oil drain port and canister first valve. The second coupler hose is connected between compressor refrigerant outlet port and canister second valve. A closed fluid and gaseous loop is established between the compressor and the canister during oil augmentation operations.

The closed loop oil service system utilizes a canister containing compressor lubricating oil and having a long stem first valve and a short stem second valve. Depending on the mode of oil service being performed the system may also incorporate a refrigerant recovery unit, a refrigerant drum or a clear calibrated fluid injection device. The system also includes at least a pair of coupler hoses which fluidly and gaseously connect the canister valves and compressor ports in varying configurations. In one embodiment, a closed loop calibrated oil augmentation system is formed by incorporating a coupler hose and a clear calibrated fluid injection device.
