    • In order to reduce the amount of refrigerant circulating within a variable displacement compressor to thereby improve compression efficiency, a control valve is configured to comprise a ball valve for controlling the flow rate of refrigerant flowing from a discharge chamber to a crankcase, a spool valve for controlling the flow rate of refrigerant flowing from the crankcase to a suction chamber, a diaphragm for sensing suction pressure, and a solenoid for setting the suction pressure, wherein the spool valve starts flow rate control after the ball valve is fully closed or nearly fully closed, and the ball valve starts flow rate control after the valve lift of the spool valve is minimized or nearly minimized. As a result, a region is almost eliminated in which the ball valve and the spool valve are both open simultaneously during switching of flow rate control between the ball valve and the spool valve, which makes it possible to minimize the flow rate of the refrigerant circulating within the compressor without contributing to a refrigerating operation, to thereby improve the efficiency of the compressor.
    • 为了减少在可变排量压缩机内循环的制冷剂量,从而提高压缩效率,控制阀被构造成包括用于控制从排出室流向曲轴箱的制冷剂的流量的球阀,用于 控制从曲轴箱流到吸入室的制冷剂的流量,用于感测吸入压力的隔膜和用于设定吸入压力的螺线管,其中滑阀在球阀完全关闭或几乎完全关闭之后启动流量控制 ,并且在阀芯的阀升程最小化或几乎最小化之后,球阀启动流量控制。 结果,几乎消除了在球阀和滑阀之间的流量控制切换期间球阀和滑阀同时打开的区域,这使得可以使制冷剂循环的流量最小化 在压缩机内不对制冷操作有贡献,从而提高压缩机的效率。

    • A hybrid compressor achieving simplification in the structure and capable of driving the compression unit with ease is provided. An electromagnetic clutch unit (40) is provided at a rotating shaft (11) projecting out on one side of a compression unit (10) and an electric motor unit (70) is provided at the rotating shaft (11) projecting out on the other side of the compression unit (10), so that an electromagnetic clutch unit (40) in the prior art can be utilized directly. At the same time, since the electric motor unit (70) is provided at the rotating shaft (11) projecting out the other side of the compression unit (10), the electromagnetic clutch unit and the electric motor unit are set at the same rotating shaft (11) and the compression unit (10) and the electric motor unit (70) are positioned next to each other to reduce the torsional torque generated at the rotating shaft (11).
