ABSTRACT:
A rotary compressor includes a cylinder and a motor-driven crankshaft. The crankshaft includes an eccentric portion disposed in the cylinder for forming therewith a compression chamber in which fluid is compressed. A vane is yieldably biased toward the eccentric portion to partition the compression chamber into high and low pressure portions. Consequently, the vane is reciprocated radially during rotation of the crankshaft. The crankshaft is mounted in a bearing which receives oil from an oil delivery system. That system includes an oil chamber communicating with an oil reservoir with which the vane communicates. A check valve is disposed in the oil chamber and is automatically cycled open and closed in response to variations in the fluid pressure in the oil chamber caused by reciprocation of the vane.
