摘要： A variable displacement compressor includes a swash plate guiding member that rotates integrally with and inclines relative to a drive shaft, a swash plate supported by the guiding member, and a piston engaged with the swash plate via a shoe. A clutch is located between the guiding member and the swash plate. The clutch is switched between an engaged state, where the clutch permits the guiding member and the swash plate to rotate integrally, and a disengaged state, where the clutch permits the guiding member and the swash plate to rotate relative to each other. Therefore, the compressor is capable of switching between a state where improving the displacement controllability is prioritized and a state where reduction of mechanical loss between the swash plate and the shoes is prioritized.

摘要： A variable displacement compressor for efficiently cooling and lubricating seals arranged on a rotary shaft. The seals are arranged at end portions of the rotary shaft that project from a housing of the compressor. A first lubrication chamber is defined by a first seal in the housing around the front end portion of the rotary shaft. A second lubrication chamber is defined by a second seal in the housing around the rear end portion of the rotary shaft. A shaft passage extends through the rotary shaft to connect the first and second lubrication chambers. Refrigerant gas including lubricating oil flows from a crank chamber to a suction chamber via the first lubrication chamber, the shaft passage, and the second lubrication chamber. This efficiently cools and lubricates the seals.

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： A control valve in a compressor that adjusts the discharge displacement based on controlling of an inclination of a cam plate. The compressor includes a supply passage for connecting a discharge chamber with a crank chamber. The control valve is placed midway on the supply passage. The control valve has a valve body. The valve body moves in a first direction to open the supply passage and moves in the second direction to close the supply passage. A reacting member reacts to suction pressure. A first transmitting member is placed between the reacting member and the valve body. A solenoid is opposed to the reacting member with respect to the valve body. The solenoid urges the valve body in the second direction via a second transmitting member when the solenoid is excited. An urging device urges the valve body in the first direction, The first transmitting member connects the reacting member with the valve body to move the valve body toward or away from the reacting member. The urging device causes the valve body to fully open the supply passage when the solenoid is de-exited.

摘要： A scroll type compressor has a fixed scroll in a housing and a movable scroll opposed to the fixed scroll to define a compression chamber with the fixed scroll. Gas introduced into a suction chamber via an inlet is compressed in the compression chamber and then is discharged to a discharge chamber via a discharge port to exhaust the compressed gas from an outlet to the outside of the compressor in accordance with the circular movement of the movable scroll. A part of the discharge chamber is defined in the fixed scroll. An outlet flange protrudes from the fixed scroll. The outlet flange includes the outlet which communicates with the discharge chamber.

摘要： A scroll type compressor comprises an immovable scroll defining a spiral space, and a refrigerant is introduced into an outerhost zone of the spiral space. The compressor further comprises a movable scroll engaged with the immovable scroll such that the outermost zone of the spiral space is divided into an inner section and an outer section by an outermost portion of the movable scroll. The movable scroll is revolved around a center axis of the immovable scroll such that the inner and outer sections are alternatively displaced as a compression chamber toward a center of the immovable scroll, and a refrigerant inlet port of the inner section is defined by a termination of the outermost portion of the movable scroll. The termination is disengaged from and engaged with the immovable scroll during the revolution of the movable scroll to close and open the inlet port of the inner section. The immovable scroll has a communication passage formed in a base portion thereof, and the inner and outer section is in communication with each other through the communication passage only when the termination is disengaged from the immovable scroll so that the inlet port of the inner section is opened, whereby the refrigerant can be fed to the inner section not only through the inlet port thereof, but also through the communication passage until the termination is engaged with the immovable scroll so that the inlet port of the inner section is closed.

摘要： In a scroll type compressor, a movable scroll is engaged with an immovable scroll so that spaces are formed for taking in a fluid to be compressed. The movable scroll is revolved around a central axis of the immovable scroll, so that the spaces are displaced toward the centers of the walls while a volume thereof is reduced to compress the fluid therein. The revolution of the movable scroll is converted from a rotation of a drive shaft through an eccentric mechanism provided therebetween. The shaft is rotatably supported by first and second angular bearings, which are spaced apart from each other along a longitudinal axis of the shaft and are far from and adjacent to the eccentric mechanism, respectively. The first and second bearings are correlatively oriented, and thus an increase of a load to which the second bearing is subjected due to a force exerted upon the shaft in a cantilever manner during a compression operation is suppressed.

摘要： In a swash plate type compressor, refrigerant in a discharge pressure region is introduced into a crank chamber through a supply passage while the refrigerant in the crank chamber is drawn out to a suction pressure region through a bleed passage for controlling pressure in the crank chamber, whereby inclination angle of a swash plate is changed. A heat-generating sliding portion is provided in the crank chamber. The supply passage includes a communication port that communicates with the crank chamber and a first throttle portion for throttling the refrigerant. At least parts of the supply passage and the bleed passage are formed in a drive shaft. A part of the bleed passage formed in the drive shaft is located between a part of the supply passage formed in the drive shaft and an outer peripheral surface of the drive shaft.
