Abstract
A compressor oil diversion and collection system used in a compressor having a housing, a crankshaft having shaft seals, refrigerant and a compression device for compressing the refrigerant. The system includes a shaft sealing mechanism that uses a lubricant for preventing compressor refrigerant from leaking out of the compressor housing and has a space where the lubricant collects. A diversion mechanism is deployed for directing excess amounts of said lubricant from the space to a receiver for receiving the excess amounts of said lubricant from the diversion mechanism. The receiver may be in the form of an internal cavity which includes a removable cartridge located in the cavity for collecting the excess amounts of said lubricant, an external collection reservoir or an external drainage tube.
