ROTARY COMPRESSOR

摘要

A rotary compressor is provided to prevent refrigerant inside or outside a cylinder from permeating into a vane and a vane slot by forming an oil film between the vane and the vane slot, and realize smooth sliding motion of the vane. A rotary compressor includes a cylinder forming a compression chamber, and a vane(240) sliding in a vane slot(241) formed at a side of the cylinder for defining the compression chamber into suction and compression spaces(221a,221b). A discharge chamber has an upper flange coupled with an upper part of the cylinder and a discharge muffler reducing discharge noise of compressed refrigerant. Connection paths(250) are formed in the vane slot to be connected to the discharge chamber, so that oil of the discharge chamber is supplied via the connection path to the vane slot, forming an oil film between the vane slot and the vane.
