Variabler Verdrängungskompressor mit Rückschlagventil

摘要

A variable capacity type compressor has a swash plate (16), pistons reciprocating in the cylinder bores, a suction chamber (7a), and a discharge chamber (7b) with a check valve (33) downstream. The check valve (33) has a valve element (72) arranged in the case (71) for cooperation with the valve seat (70). The case (71) has a flow passage through the communication hole (71b) to the outside circuit. An annular groove is formed in the outer peripheral surface (72f) of the valve element (72) to allow the flow of leaking gas from the clearance between valve element (72) and valve housing to the exterior.
