    • A variable capacity compressor like a swash plate type where a pressurized fluid is fed to a control pressure chamber such as a swash plate chamber to apply a backpressure to a piston etc. and the backpressure is changed by the capacity control valve, wherein the valve is streamlined and reduced in cost by providing a simple valve such as a two-way solenoid valve as a capacity control valve in a feed path to or discharge path from the control pressure chamber. By controlling the duty ratio of the valve, it is possible to smoothly change the capacity of the compressor. Further, a torque sensor is provided at a drive shaft, and the valve is controlled by a control unit to change the discharge capacity of the compressor in accordance with that detection value.

    • A scroll compressor having injection ports 70A and 70B opened to operating chambers Vc during a predetermined period of a complete compression cycle, so that a part of the refrigerant circulating in a refrigerating system is injected into the compression chambers from the injection ports. The injection ports are opened to an intermediate pressure chamber, which is at a pressure between the pressure of the refrigerant sucked into the compressor and the pressure of the refrigerant discharged from the compressor. The intermediate pressure chamber is arranged so as to eliminate pressure pulsations therein. Check valves 72A and 72B are provided in an end plate 54 of a stationary scroll member 50. Furthermore, relief valves may also be provided in the end plate for releasing the pressure of the operating chambers to a low pressure side of the refrigerating system.
