摘要： A mechanism for drawing in refrigerant to front compression chambers (28a) of a double-headed piston type compressor differs from a mechanism for drawing in refrigerant to rear compression chambers (29a). More specifically, the mechanism for drawing in refrigerant to the front compression chambers (28a) include suction valves (18a) configured by flap valves. The mechanism for drawing in refrigerant to the rear compression chambers (29a) is configured by a rotary valve (35). Thus, pulsation of the compressor is reduced, so that the generation of noise is suppressed. As a result, a quiet compressor is achieved.

摘要： A compressor includes a rotary shaft, a swash plate, a cylinder block, plural pistons, a crank chamber, a housing, plural passages, a thrust bearing, and an anti-rotation mechanism. The crank chamber accommodates therein the swash plate, and refrigerant of suction pressure is introduced into the crank chamber. The housing is connected to the cylinder block and forms therein a suction chamber and a discharge chamber. The plural passages are provided for communication between the crank chamber and the suction chamber. The thrust bearing is provided between the swash plate and the cylinder block so as to receive thrust load from the swash plate. The thrust bearing has a thrust race located adjacent to the cylinder block. The anti-rotation mechanism is provided for preventing relative rotation of the thrust race to the cylinder block. The anti-rotation mechanism restricts the fluid flow through a specific passage of the plural passages.

摘要： A valve structure includes a central valve plate having a valve hole, and a flexible valve element having a root portion lying on the central valve plate and a bendable portion to open and close the valve hole. A retainer element has a retaining surface to restrict deformation of the valve element when it is bent toward the retainer element to open the valve hole. The profile is expressed in a two-dimensional coordinate system (x, y), and the freely bent shape is represented by coordinates (x, f(x)) obtained by pushing the valve element at an abscissa position corresponding to the center of the valve element. The retaining surface has a profile containing a coordinate (x′, f(x′)−K) so that the profile is displaced toward the central valve plate with respect to a freely bent shape of the valve element.

摘要： In a double-headed piston type compressor provided with a rotary valve in a rotary shaft, the rotary valve has an introducing port for introducing refrigerant from a suction-pressure region through a supply passage and a respective suction port into a compression chamber. A shaft seal between a front housing and the rotary shaft for preventing leakage of refrigerant along a peripheral surface of the rotary shaft is accommodated in a shaft seal chamber formed in the front housing. A communication passage connects the shaft seal chamber to the cam chamber. A communication groove is formed in an outer peripheral surface of the rotary shaft that forms the rotary valve adjacent to the front housing for communication between the introducing port and the shaft seal chamber. The supply passage and the cam chamber are in communication through the communication groove, the shaft seal chamber and the communication passage.
