ABSTRACT:
In a scroll compressor, at least one suction port for gas is opened in a stationary end plate which has a spiral wrap. Gas is drawn directly into the compression chambers from the suction port. In addition, the suction port has an opening straddling both the radially extending surface of the stationary end plate at the outermost circumference of the compression chambers and the compression chamber side wall that is perpendicular to the radially extending surface, and the opening area of the suction port is relatively large.
