Claims

[Scope of utility model registration request]

A compressor that compresses fluid sucked in from a suction side passage in a compression chamber and discharges it from a discharge side passage, a bypass passage communicating the compression chamber and the suction side passage, and a ridge provided in the discharge side passage; A variable opening/closing valve is provided in the bypass passage and the flow area of the valve changes continuously according to the pressure difference before and after the throttle. A variable capacity compressor characterized in that the amount of fluid to be compressed is controlled by continuously changing the flow rate of fluid returning to a passage.
