    • PROBLEM TO BE SOLVED: To reduce the manhour for development of an air conditioning device while improving the drivability of a vehicle.
      SOLUTION: A pressure sensor 151a, a torque arithmetic unit 152, and a communication unit 156 capable of performing data communication of another equipment by a vehicle internal data communication protocol are integrated (packaged up) to a compressor so that the compressor itself can calculate a drive torque. Accordingly, since the drive torque can be calculated in a short time, an engine ECU can control an engine to quickly generate a torque according to the power (torque) required by the compressor in the engine. Since it is not necessary to separately provide a pressure sensor on the refrigerant outlet side of a condenser, there is no necessity to consider the pressure loss differed every vehicle model (every on-vehicle condenser), and the manhour for development of the air conditioning device can be reduced.

    • 要解决的问题:为了减少用于开发空调装置的工作时间,同时提高车辆的驾驶性能。 解决方案:能够通过车辆内部数据通信协议执行另一设备的数据通信的压力传感器151a,扭矩运算单元152和通信单元156被集成(封装)到压缩机,使得压缩机本身可以计算出 驱动力矩。 因此,由于可以在短时间内计算驱动转矩,所以发动机ECU可以控制发动机,以根据发动机中的压缩机所需的功率(转矩)来快速产生转矩。 由于不需要在冷凝器的制冷剂出口侧分别设置压力传感器,因此不需要考虑每个车辆型号(每个车载冷凝器)的压力损失和空调的开发的小时 设备可以减少。

    • PROBLEM TO BE SOLVED: To stably separate a refrigerant from lubricating oil irrespective of discharge quantity. SOLUTION: Out of both first and second communicating passages 122 and 123 interconnecting a discharge chamber 115 and a separate chamber 116 together, a differential pressure regulating valve 124 to open or close these discharge and separate chambers 115 and 116 by pressure differential, is installed in the second communicating passage 123. With this, if a discharge quantity is increased, this differential pressure regulating valve 124 is opened, and on the other hand, if the discharge quantity is decreased, the valve 124 is closed. Accordingly, since a pressure differential lying between both these chambers 115 and 116 is controlled so as to make it become within the specified range, such a possibility that the flow velocity of a refrigerant in time of its flow into the separate chamber 116 might to largely lowered is preventable without entailing any drop in the efficiency of a compressor 100. Therefore, the refrigerant and lubricating oil are stably separable irrespective of the discharge quantity.

    • PROBLEM TO BE SOLVED: To control an inclined angle of a swash plate without allowing a compressor body to become large by tilting the swash plate so that a greater number of pistons reaching a top dead center, of a plurality of pistons, move toward a forward end of shaft rotation as an angle formed between an axis line and the swash plate becomes greater. SOLUTION: A surface 110a of a swash plate 110 is inclined in two different directions with respect to an axis line 101a of a shaft 110; namely, in a direction of a greater or a smaller inclined angle θ and in a direction of a greater or a smaller angle between a pin reference surface and the axis line 101a. At the same time, this compressor is constructed so as to rock in a direction of a greater or a smaller inclined angle about a pin 115 as a center. Then, a piston that reaches its top dead center among others of a plurality of pistons 111 moves toward a forward end of rotation of the shaft 101 as the inclined angle θbecomes greater. This allows moment equilibrium to be varied even if a distance between an instantaneous center of the swash plate 110 and the axis line 101a is made smaller. It is thus possible to control the inclined angle θwithout allowing a compressor body to become large.
