Claims

[Scope of utility model registration request]

A bypass hole is bored in the mid-compression portion of the compressor cylinder, and the downstream side thereof is connected to the discharge side and suction side of the compressor as a bypass passage, and a valve seat is provided in the bypass hole in parallel with the bypass passage, and the bypass passage is connected to the discharge side and the suction side of the compressor. A compressor characterized in that the valve seat is opened and closed by a valve body that is movable in a direction perpendicular to the valve body.
