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.

摘要： A swash plate includes a boss, which is mounted on the drive shaft, and a plate portion, which extends from the boss to be inclined with respect to the drive shaft. A rotary valve includes a suction passage, which sequentially connects cylinder bores in a suction stroke via an associated guide passage. An introduction guide communicates with the shaft bore to introduce the refrigerant gas in the swash plate chamber to the rotary valve. The introduction guide faces the boss and extends in the radial direction from the shaft bore beyond the boss. Therefore, suction efficiency of refrigerant gas from the swash plate chamber to the cylinder bore has improved.

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 swash-plate-type compressor of a double-headed-piston configuration, wherein: a front intake chamber is formed set apart from a swash plate chamber so as to be positioned in a narrow space between circumferentially arranged front cylinder bores; and an intake-chamber-communication path is formed in a cylinder block, the intake-chamber-communication path allowing the front intake chamber and a shaft hole to communicate. A front-bore-communication path is formed on the cylinder block, the communication path allowing each of the plurality of front cylinder bores to communicate with the shaft hole. A front rotary valve is provided on a rotating shaft in which a lead-in groove is formed. The lead-in groove allows the intake-chamber communication path and the front-bore communication path to communicate in the stated order, while the lead-in groove rotates integrally with the rotating shaft. In the compact swash-plate-type compressor any decrease in pulsation or intake efficiency is minimized.

The swash plate chamber communicates with the inlet port and also with the first and second guide holes via the first and second supply ports, respectively. A distance from the inlet port to the first supply port when the first supply port is moved closest to the inlet port is greater than a distance from the inlet port to the second supply port when the second supply port is moved closest to the inlet port, and the smallest flow passage area in the first supply port and the first guide hole is greater than the smallest flow passage area in the second supply port and the second guide hole.

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.
