Abstract
PURPOSE: To match the output of a compressor to the ability of an evaporator by providing a bypass passage between the intermediate of the compression stroke and the suction port and opening or closing the passage in accordance with the suction port pressure, in a compressor such as an automobile cooling device.
CONSTITUTION: A bypass hole 12 is positioned in a range from a suction hole 8a towards the rotational direction A of a rotor 6 up to an exhaust hole 8b. One end of the bypass hole 12 is opened within a compression chamber 13, and another end is opened in a bypass passage 14. The compression chamber 13 is communicated with the upstream of the suction hole 8a by the bypass hole 12 and the bypass passage 14. Since the bypass passage 14 is opened or closed in accordance with the coolant pressure from the evaporator 5 outlet to the compressor suction port 8a, when the coolant pressure from the evaporator 5 outlet to the compressor suction port 8a becomes less than the set pressure, the bypass passage 14 is opened, and a part of the coolant in the intermediate of the compression is bypassed to the upstream side of the suction port 8a.
