SELF-EXCITING VIBRATION PREVENTING MECHANISM FOR SUCTION VALVE OF ROCKING CAM PLATE TYPE COMPRESSOR

摘要

PURPOSE:To prevent production of self-exciting vibration of a suction valve and the generation of noise due to the self-exciting vibration, by a method wherein a lift allowable amount of the suction valve is automatically regulated in linkage with a change in the rocking inclination angle of a wobble plate. CONSTITUTION:A stopper material 23 is forward and backward movably engaged in a manner to be positioned facing the tip part of a suction valve 11 with a spring 29 therebetween, and is moved forward and backward through the change in the rocking inclination angle of a dry plate 20 and the wobble plate 21. Namely, under a state in that a cooling load in a car room is high and a piston 16 is reciprocated with a high stroke left, a high life allowable amount is obtained. Under a state in that a cooling load in a car room is low and the piston 16 is reciprocated with a low stroke left, a low lift allowable amount is obtained. This constitution enables prevention of production of self- exciting vibration of the suction valve 11 and the generation of noise due to the self-exciting vibration.
