    • A hybrid compressor system has a hybrid compressor for compressing refrigerant. The compressor is selectively driven by one of a first drive source and a second drive source. The hybrid compressor system also includes a first one-way clutch, a driver for driving the second drive source, a sensor for detecting a rotational state of the first drive source and a controller. The first one-way clutch is arranged on a first power transmission path between the compressor and the first drive source for permitting power transmission from the first drive source to the compressor. The controller is electrically connected to the driver and the sensor. When a drive source of the compressor is switched from the second drive source to the first drive source, the controller orders the driver to stop the second drive source after the rotation of the first drive source is detected.

    • An air conditioning system for a vehicle that is driven by a vehicular power source. The system has a compressor selectively operable by the vehicular power source and an electric motor. The electric motor is used as a drive force of the compressor when the vehicular power source is in a non-operative state. The compressor compresses refrigerant gas introduced into a suction chamber from an external refrigerant circuit. A displacement of the compressor is variable, based on a differential pressure. The compressor has a control valve that is disposed on a refrigerant passage communicating with the crank chamber. The control valve has a valve plunger for changing an opening size of the control valve to adjust pressure in the crank chamber. The air conditioning system comprises pressure sensing member, actuator, and controller. The pressure sensing member is disposed in the control valve and applies biasing force to the plunger based on pressure in the external circuit. The biasing force is applied to cancel change of the pressure in the external circuit. The actuator is disposed in the control valve and applies reverse force against the biasing force to the plunger. The plunger is moved to increase the displacement by the reverse force. The controller controls the actuator to increase the reverse force in steps by a magnitude that is small enough that the electric motor is able to stably drive the compressor.
    • 一种由车辆电源驱动的车辆空调系统。 该系统具有通过车辆电源和电动机选择性地操作的压缩机。 当车辆电源处于非操作状态时,电动机用作压缩机的驱动力。 压缩机将从外部制冷剂回路引入吸入室的制冷剂气体压缩。 基于压差,压缩机的位移是可变的。 压缩机具有设置在与曲柄室连通的制冷剂通路上的控制阀。 控制阀具有用于改变控制阀的开口尺寸以调节曲柄室中的压力的​​阀柱塞。 空调系统包括压力传感构件,致动器和控制器。 压力感测部件设置在控制阀中,并且基于外部电路中的压力向柱塞施加偏压力。 施加偏压力以消除外部电路中的压力变化。 致动器设置在控制阀中,并且反作用力施加到柱塞上。 移动柱塞以通过反向力增加位移。 控制器控制致动器以逐步增加反向力,其量值足够小以使电动机能够稳定地驱动压缩机。

    • An electric motor drive device 1000 includes: an inverter 3 that drives a motor 4, a voltage division circuit 2 that serves as a neutral point potential detection unit that detects a neutral point potential of a stator winding of the motor 4; and a controller 1 that estimates a rotor position of the motor 4 based on the detected neutral point potential, and that controls the inverter 3 based on an estimation result. A ground potential of the controller 1 is set to a negative side potential or a positive side potential of a DC voltage that is supplied to the inverter 3. The voltage division circuit 2 detects the neutral point potential with reference to the negative side potential or the positive side potential. The controller 1 estimates the rotor position based on a difference between a first neutral point potential detected during the ON/OFF operation of the inverter 3 and a first fixed reference potential (⅔)Emax, and based on a difference between a second neutral point potential detected during the ON/OFF operation and a second fixed reference potential (⅓)Emax.
