Abstract:
A compressor oil recovery device for use in removing oil from compressors typically found on condensing units used in air conditioning or refrigeration applications, said compressor oil recovery device comprising:a canister, said canister having a generally cylindrical shape, having a disc-shaped base and a side wall extending vertically therefrom, forming a top rim and creating a hollow interior cavity;a lid, consisting of a disc-shaped plate with a top side and a bottom side, with a U-shaped channel located on said bottom side and extending around the perimeter of said bottom side, a vacuum port, said vacuum port penetrating said lid and in fluid communication with said interior cavity of said canister, a suction port, said suction port penetrating said lid and in fluid communication with said interior cavity of said canister, a drain port, said drain port penetrating said lid and in fluid communication with said interior cavity of said canister, and a vacuum release port, said vacuum release port penetrating said lid and in fluid communication with said interior cavity of said canister;a vacuum hose, consisting of a linearly elongated flexible tube, having a first end in fluid communication with a second end, said first end attached to a standard threaded hose fitting and said second end attached to a standard threaded hose fitting;a suction hose, consisting of a linearly elongated flexible tube, having a third end in fluid communication with a fourth end, said third end attached to a standard threaded hose fitting and said fourth end attached to a standard threaded hose fitting; anda gauge manifold hose, consisting of a linearly elongated flexible tube, having a fifth end in fluid communication with a sixth end, said fifth end attached to a standard threaded hose fitting and said sixth end attached to a standard threaded hose fitting;wherein said compressor oil recovery device is arranged in conjunction with a vacuum pump and a compressor such that, upon activating said vacuum pump, a vacuum is drawn, by said vacuum pump, through said vacuum hose, through said canister, through said suction hose, through said gauge manifold hose and into the compressor oil reservoir through said gauge manifold, thereby drawing said compressor oil through said gauge manifold hose and through said suction hose, depositing and collecting said compressor oil in said canister.
