    • 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 control valve for a variable displacement compressor in refrigerant circuit permits the compressor displacement to be accurately controlled regardless of the thermal load on an evaporator. The refrigerant circuit includes a high pressure pipe, which extends between a discharge chamber of the compressor and a condenser. A first pressure monitoring point is located in the discharge chamber. A second pressure monitoring point is located in the high pressure pipe. A supply passage connects the second pressure monitoring point with a crank chamber of the compressor. The control valve is located in the supply passage and adjusts the opening size of the supply passage in accordance with the difference between the pressure at the first pressure monitoring point and the pressure at the second pressure monitoring point. The control valve includes a solenoid for determining the target value of the pressure difference. The control valve operates to maintain the determined target value.
    • 用于制冷剂回路中的可变排量压缩机的控制阀允许压缩机排量被精确地控制,而与蒸发器上的热负荷无关。 制冷剂回路包括在压缩机的排出室和冷凝器之间延伸的高压管。 第一个压力监测点位于放电室中。 第二个压力监测点位于高压管道中。 供给通道将第二压力监测点与压缩机的曲柄室连接。 控制阀位于供给通道中,并根据第一压力监测点的压力与第二压力监测点的压力之差来调节供油通道的开度。 控制阀包括用于确定压差的目标值的螺线管。 控制阀操作以维持所确定的目标值。
