ABSTRACT:
Reciprocation of the vane of a rolling piston compressor can produce a pumping action which draws oil from the sump and discharges it into the gas exiting from the discharge chamber. By providing a restricted communication between the sump and the spring cavity, the amount of oil being pumped can be reduced to a level just sufficient for lubricating the vane.
