1. A compressor crankcase oil reclamation system, comprising:
a coalescence filter adapted to be coupled to a pressure relief vent of a compressor crankcase for separating oil from an oil/gas mixture exiting the compressor crankcase via the pressure relief vent;
a reservoir in fluid communication with said coalescence filter for receiving the oil so-separated;
a sensor coupled to said reservoir and adapted to detect a first level of the oil in said reservoir and a second level of the oil in said reservoir, said sensor generating a first signal when the first level is detected, and said sensor generating a second signal when the second level is detected;
a pump in fluid communication with said reservoir and coupled to said sensor, wherein said pump is activated to pump the oil from said reservoir when said first signal is generated, and wherein said pump is deactivated when said second signal is generated; and
a check valve in fluid communication with said pump and adapted to be in fluid communication with the compressor crankcase for restricting flow of the oil from said reservoir to a single flow direction running from said reservoir to the compressor crankcase.
