Abstract
A fluid compressor comprises a rotary member, a cylinder, and a closed casing for receiving the rotary member and cylinder. The rotary member and cylinder are relatively turned so that a fluid is drawn into work chambers through a suction port, successively compressed and conveyed toward a discharge port through the work chambers, and discharged outside. The fluid compressor is provided with a control valve means. When pressure in the work chambers exceeds a predetermined value during the compressing process, the control valve releases the pressure through a discharge or suction end of the cylinder, or to the inside of the casing.
