摘要： A swash plate compressor includes a housing that has a cylinder bore and rotatably supports a drive shaft. A swash plate is operatively coupled to the drive shaft for rotation therewith. A piston is accommodated in the cylinder bore for reciprocating movement. First and second spaced shoes are fitted to the piston on a side adjacent to the cylinder bore and on a side away from the cylinder bore, respectively, for coupling the piston to the swash plate. The rolling body is mounted on the swash plate through a bearing and in slide contact with the first shoe. A surface of the rolling body in slide contact with the first shoe or a surface of the first shoe in slide contact with the rolling body has a diamond-like carbon film. A surface of the rolling body in rolling contact with the bearing exposes a base material of the rolling body.

摘要： A displacement control valve for a variable displacement compressor includes a first valve hole forming a part of a supply passage and a second valve hole forming a part of a discharge passage. Displacement of a reciprocating body is transmitted to each of first and second valve bodies so that each valve body opens or closes the corresponding valve hole. When the reciprocating body is within a predetermined displacement range, a double closing state occurs, in which the first valve body closes the first valve hole and the second valve hole closes the second valve hole. When the reciprocating body is out of the displacement range, a single closing state occurs. Therefore, the control valve prevents the first valve hole from opening concurrently with the second valve hole.

摘要： In a piston type compressor, a piston is respectively accommodated in a plurality of cylinder bores arranged around a rotary shaft. A rotary valve has a suction guiding passage for introducing gas from a suction pressure region into a compression chamber when in communication therebetween. A suction timing control passage is formed in the rotary valve and is constantly in communication with the suction pressure region at first end, the suction timing control passage precedes the suction guiding passage communicating with the compression chamber at second end. A suction timing control valve is arranged in the control passage, having a valve body which opens and closes the control passage in response to difference between force resulting from pressure on a side of the suction pressure region to open the valve body and force resulting from pressure on a side of the compression chamber to close the valve body.

摘要： In a variable-capacity swash-plate type compressor, which can vary the outlet capacity by controlling an inclination angle of a swash plate, the swash plate is aligned by contacting a washer (19) with a tapered surface to the swash plate (18). Thus, in a case where a compression operation is not carried out or in a case where a compression operation is carried out at a small outlet capacity regarded as zero substantially, the noises, etc., which generate between the swash plate and a driving shaft (6), are inhibited.

摘要： A variable displacement compressor has a crank chamber defined in a housing. A drive shaft is arranged in the housing. A piston is accommodated in the cylinder bore. A swash plate is connected to the piston to convert a rotation of the drive shaft. A retainer surface is arranged in the housing and extends substantially perpendicular to the axis of the drive shaft. A restricting mechanism is arranged between the swash plate and the retainer surface. The restricting mechanism receives the swash plate and restricts movement of the swash plate when the inclination of the swash plate decreases.

摘要： Pistons are accommodated in each cylinder bores of a variable displacement compressor. A swash plate is coupled to the piston for converting rotation of the drive shaft to reciprocation of the pistons. A thrust bearing located between a rotor and a housing of the compressor. The outermost load-bearing points of the thrust bearing are radially farther from the axis of the drive shaft than the axes of the pistons. This permits the thrust bearing to directly receive a reaction forces from the pistons through the rotor without applying a moment to the bearing.

摘要： A compressor has a cam plate located in a crank chamber and mounted on a drive shaft and a piston coupled to the cam plate and located in a cylinder bore. The piston compresses gas supplied to the cylinder bore from a separate external circuit by way of a suction chamber and discharges the compressed gas to the external circuit by way of a discharge chamber. The cam plate is tiltable between a maximum inclined angle position and a minimum inclined angle position with respect to a plane perpendicular to an axis of the drive shaft according to a difference between the pressure in the crank chamber and the pressure in the cylinder bore. The piston moves by the stroke based on an inclination of the cam plate to control the displacement of the compressor. A valve is placed between the discharge chamber and the external circuit. The valve selectively connects and disconnects the discharge chamber with the external circuit based on a difference between the pressure acting on the upstream side of the valve and the pressure acting on the downstream side of the valve.
