Abstract
A scroll compressor is provided, the scroll compressor having a block insertion groove recessed by a predetermined depth into a rear surface of a non-orbiting scroll to accommodate a discharge port and a plurality of bypass holes, and a retainer block having a bypass valve that opens and closes the plurality of bypass holes fixedly inserted into the block insertion groove. The bypass valve may be fixed to a first axial side surface of the retainer block facing the block insertion groove. Through this, the bypass valve that suppresses or prevents overcompression of a compression chamber is not fastened to a non-orbiting end plate, which may allow the non-orbiting end plate to be reduced in thickness. This may shorten lengths of the plurality of bypass holes and the discharge port by the reduced thickness of the non-orbiting end plate, thereby decreasing a dead volume in the plurality of bypass holes and the discharge port.
