Abstract (en)
[origin: WO2011086908A1] Refrigerant compressor has a suction throttle valve (60) provided in the midway of the suction passage (36) for guiding the refrigerant suctioned from the suction inlet (35) to the suction chamber (33). The suction throttle valve (60) adjusts the passage area of the refrigerant passing through the suction passage (36) by moving in a direction substantially perpendicular to the suction passage (36). High pressure oil separated in an oil separator provided in the discharge area is guided to one side (62a) of the suction throttle valve (60). Refrigerant from the suction area is guided to the other end side (62b) of the suction throttle valve (60). Furthermore, a spring (63) biases the suction throttle valve towards the one end side (62a), thereby reducing the passage area of the suction passage (36).
