    • An air conditioner for air conditioning the interior of a compartment includes a compressor and an electric motor. The compressor compresses refrigerant gas and changes the displacement. The electric motor drives the compressor. A motor controller rotates the motor at a constant reference speed. A detection device detects information related to the thermal load on the air conditioner. A current sensor detects the value of current supplied to the electric motor. A controller controls the compressor based on the detected thermal load information and the detected current value. The controller computes a target torque of the compressor based on the thermal load information. In accordance with the computed target torque, the controller computes a target current value to be supplied to the electric motor. The controller further controls the displacement of the compressor such that the detected current value matches the target current value.

    • 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。
