摘要： Compressor are taught that may include a suction port to draw refrigerant and a discharge port to discharge compressed refrigerant. A driving shaft is disposed within a compressor driving chamber. A swash plate is inclinably and slidably coupled to the driving shaft. The swash plate rotates together with the driving shaft at an inclination angle with respect to a plane perpendicular to the rotational axis of the driving shaft. A cylinder bore is disposed adjacent to the compressor driving chamber. A piston is disposed within the cylinder bore and an end portion of the piston is connected to a peripheral edge of the swash plate by a shoe. Preferably, the piston reciprocates within the cylinder bore to compress the refrigerant in response to rotation of the inclined swash plate. A rotor is connected to the driving shaft. A hinge mechanism connects the swash plate with the rotor and transmits torque from the driving shaft to the swash plate regardless of the inclination angle of the swash plate. The hinge mechanism includes a projection disposed on one of the rotor or the swash plate and at least one arm disposed on the other of the rotor or the swash plate. The projection has a recessed structure and at least one arm is coupled to the projection to transmit torque from the driving shaft.

摘要： A variable displacement compressor has a housing, a drive shaft, a rotor, a swash plate, a piston and a decelerating mechanism. The housing includes a cylinder bore and supports the drive shaft. The rotor is secured to the drive shaft. The swash plate is operatively connected to the rotor and the drive shaft so as to rotate therewith and varies its inclination angle relative to the drive shaft. The piston is connected to the swash plate so as to reciprocate in the cylinder bore with rotation of the swash plate. A stroke of the piston varies in accordance with the inclination angle of the swash plate. The deceleration mechanism between the rotor and the swash plate decelerates the inclination speed of the swash plate in a range from a near maximum inclination angle to the maximum inclination angle when the swash plate inclines to increase the stroke of the piston.

A discharge valve forming plate is provided between a valve plate having at least one discharge port through which a fluid compressed in a compression chamber of a cylinder block assembly is discharged into a discharge chamber of a housing and the cylinder block assembly. A retainer for restricting the magnitude of opening of a discharge valve is integrally formed in a metal gasket which is provided between the discharge valve forming plate and the housing. The housing is provided with a restricting section at a position corresponding to a proximal portion of a rising portion of the retainer for restricting the proximal portion of the top surface of a rising portion.

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 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： 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.
