    • A piston type compressor has a housing, a crank chamber and a drive shaft supported by the housing. A front restriction and a rear restriction are located in the housing. The front and rear restrictions restrict axial movement of the drive shaft. The front restriction restricts forward movement of the drive shaft. The rear restriction restricts rearward axial movement of the drive shaft. A first clearance is located between the rear end of the drive shaft and the rear restriction when the drive shaft is restricted by the front restriction. A second clearance is formed between the piston and a valve plate when the drive shaft is restricted by the front restriction and when the piston is in the top dead center position. The first clearance is narrower than the second clearance. The method of assembly the piston easily sets the first clearance.

    • A control valve is used for a variable displacement compressor. The compressor has a crank chamber and a supply passage. The control valve includes a valve housing. A valve chamber is defined in the valve housing. A valve body is accommodated in the valve chamber for adjusting the opening size of the supply passage. A pressure sensing chamber is defined in the valve housing. A pressure sensing member separates the pressure sensing chamber into a first pressure chamber and a second pressure chamber. The pressure at a first pressure monitoring point is applied to the first pressure chamber. The pressure at a second pressure monitoring point located is applied to the second pressure chamber. The pressure sensing member moves the valve body in accordance with the pressure difference between the first pressure chamber and the second pressure chamber. The pressure sensing member is a bellows or a diaphragm, an actuator applies force to the pressure sensing member in accordance with external commands. The force is applied by the actuator corresponds to a target value of the pressure difference. The pressure sensing member moves the valve body such that the pressure difference seeks the target value.
    • 控制阀用于可变排量压缩机。 压缩机具有曲柄室和供给通道。 控制阀包括阀壳体。 阀室定义在阀壳体中。 阀体容纳在阀室中,用于调节供给通道的开口尺寸。 压力传感室被限定在阀壳体中。 压力感测构件将压力感测室分离成第一压力室和第二压力室。 将第一压力监测点处的压力施加到第一压力室。 位于第二压力监测点的压力被施加到第二压力室。 压力检测构件根据第一压力室和第二压力室之间的压力差移动阀体。 压力感测构件是波纹管或隔膜,致动器根据外部命令向压力感测构件施加力。 致动器施加的力对应于压力差的目标值。 压力检测构件移动阀体,使得压差寻求目标值。

    • A torque limiting mechanism for transmitting power from an external drive source to the drive shat of a compressor. A pulley, which is coupled to the external drive source, has elastic members. A hub, which is attached to the drive shaft, has engaging portions. A coupler member is located between the pulley and the hub. The coupler member is engaged with the elastic members and with the engaging portions such that power is transmitted from the pulley to the hub. The urging members urge the coupler member such that the coupler member is disengaged from the engaging portions. When power is transmitted from the pulley to the hub, the elastic members maintain the coupler engaged with the elastic members and the engaging portions. When load generated due to power transmission exceeds a predetermined level, the elastic members are deformed such that the coupler member is disengaged from the elastic members. When disengaged from the elastic members, the coupler member is disengaged from the engaging portions.
    • 用于将功率从外部驱动源传输到压缩机的驱动轴的转矩限制机构。 耦合到外部驱动源的滑轮具有弹性构件。 安装在驱动轴上的轮毂具有啮合部分。 联接器构件位于滑轮和轮毂之间。 联接器构件与弹性构件和接合部分接合,使得动力从滑轮传递到轮毂。 推动构件推动联接器构件,使得联接构件从接合部分脱离。 当动力从滑轮传递到轮毂时,弹性构件保持联接器与弹性构件和接合部分啮合。 当由于动力传递而产生的载荷超过预定水平时,弹性构件变形,使得联接构件从弹性构件脱离。 当与弹性构件分离时,联接构件与接合部分脱离接合。

    • A first bleed passage and a second bleed passage each connect a crank chamber of a compressor with a suction chamber of the compressor. A first supply passage and a second supply passage each connect the crank chamber with a discharge chamber of the compressor. A first control valve adjusts the opening size of the first supply passage in response to the pressure in the suction chamber. A second control valve includes a ball valve and an electromagnetic actuator. The ball valve adjusts the opening size of the second supply passage and the opening size of the first bleed passage. The electromagnetic actuator moves the ball valve. The ball valve is moved to a first position and to a second position. At the first position, the ball valve closes the second supply passage and opens the first bleed passage. At the second position, the ball valve opens the second supply passage and closes the first bleed passage. A displacement control device, which includes the first and second control valves, readily and reliably changes the displacement of the compressor.
