A drive shaft is rotatably supported by the housing and the cylinder block. A swash plate is supported by the drive shaft in the crank chamber and is inclinable with respect to the axis of the drive shaft. A piston is accommodated in the cylinder bore so as to define a compression chamber in the cylinder bore and is coupled to the swash plate. A control mechanism includes a bleed passage for controlling the pressure in the crank chamber. The compressor is formed such that lubricating oil in the crank chamber is discharged into at least one of the suction chamber, the discharge chamber and the compression chamber while the inclination angle of the swash plate is substantially a maximum inclination angle.

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： A piston compressor includes a rotary valve having a suction guide hole. A plurality of introducing passages are formed in a cylinder block to connect compression chambers to the rotary valve. The inner circumferential surface of each cylinder bore has a suction auxiliary recess, which is connected to the outlet of the corresponding introducing passage in the circumferential direction of the cylinder bore at the end of the cylinder bore facing a valve assembly. Therefore, the compressor reduces suction resistance of gas at the beginning of the suction stroke without enlarging introducing passages formed in the cylinder block.

摘要： A supply passage is formed in a rotary shaft along the axis thereof. An expansion passage is formed in the rotary shaft in such a way as to be led to the supply passage. A pair of fluid passages are formed in the rotary shaft in such a way as to communicate with the expansion passage. The fluid passages extend in a direction orthogonal to the axis and the outlet ports of the fluid passages are open to the outer surface of the rotary shaft. The fluid passages extend from the expansion passage to a control pressure chamber, penetrating through the rotary shaft.

摘要： A variable displacement compressor has a control valve for controlling the displacement of the compressor. When the pressure in a discharge chamber of the compressor (discharge pressure) is equal to or higher than a first threshold value, a controller executes a limiting control for limiting the discharge pressure. During the limiting control, the controller gradually decreases a duty ratio, which is sent to the control valve, such that the displacement of the compressor is gradually decreased. When the duty ratio is decreased to a reference duty ratio, the controller sets the duty ratio to zero %. As a result, the compressor displacement is minimized and the discharge pressure is lowered. Therefore, the pipes of an external refrigerant circuit does not receive excessive load based on high discharge pressure.
摘要翻译：可变排量压缩机具有用于控制压缩机的排量的控制阀。当压缩机的排出室中的压力（排出压力）等于或高于第一阈值时，控制器执行用于限制排出压力的限制控制。在限制控制期间，控制器逐渐减小发送到控制阀的占空比，使得压缩机的位移逐渐减小。当占空比降低到参考占空比时，控制器将占空比设置为零％。结果，压缩机排量被最小化并且排出压力降低。因此，外部制冷剂回路的管道基于高排出压力不会受到过大的负荷。

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 piston type compressor includes a housing forming a cylinder bore. A drive shaft is supported by the housing. A cam plate is coupled to the drive shaft and is rotated by the rotation of the drive shaft. A piston is accommodated in the cylinder bore and is coupled to the cam plate. The rotation of the cam plate is converted into the reciprocating movement of the piston. In accordance with the reciprocating movement of the piston, gas is introduced into the cylinder bore, is compressed and is discharged from the cylinder bore. Compression reactive force is generated in compressing the gas by the piston, is transmitted to the housing through a compression reactive force transmission path and is received by the housing. A vibration damping member is made of a predetermined vibration damping alloy and is placed at least one location along the compression reactive force transmission path.
