Kind Code:
A1
Abstract:
Through intermittent communication between an inner circumferential side space 106i of a piston 106 and a suction chamber 110, a rotary compressor according to the present disclosure uses an opening time of an oil feeling groove 117 for the suction chamber 110 under a low rotation condition on which an oil feeding amount is desirably increased, and uses a pressure difference under a high differential pressure condition to increase the oil feeding amount. Thus, an oil feeding amount is made appropriate in a wide operation range, and high efficiency and high reliability can be achieved at the same time.
