    • 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.
    • 一种具有在整个压缩循环的预定时间内向操作室Vc开口的喷射口70A和70B的涡旋压缩机,使得在制冷系统中循环的制冷剂的一部分从喷射口喷射到压缩室中。 喷射口向中间压力室打开,中压室处于吸入压缩机的制冷剂的压力与从压缩机排出的制冷剂的压力之间的压力。 中间压力室被布置成消除其中的压力脉动。 止回阀72A和72B设置在固定涡旋构件50的端板54中。此外,也可以在端板中设置安全阀以将操作室的压力释放到制冷系统的低压侧。
