VANE ROTARY COMPRESSOR, CAPABLE OF IMPROVING SEALING PERFORMANCE AND PREVENTING REFRIGERANT FROM LEAKING BY CLOSELY ATTACHING THE LEADING END OF A VANE TO THE INNER SURFACE OF A STATOR

摘要

PURPOSE: A vane rotary compressor is provided to maintain cooling performance as the leading end of a vane is closely attached to the inner surface of a stator by pressure difference applied to both surfaces of a blade unit.;CONSTITUTION: A vane rotary compressor comprises a rotor(30) and a vane(50). The rotor rotates in a stator(20). The vane is inserted into a slot(40) of the rotor, and protrudes from the inner surface of the stator. The vane comprises an insertion unit(51) and a blade unit(52). The insertion unit is inserted into the slot of the rotor. The blade unit is extended from the leading end of the insertion unit in the rotary direction of the rotor. The blade unit of a vane is closely attached to the inner surface of the stator by pressure difference between compression chambers. The blade unit is bent at a curvature corresponding to the outer surface shape of the rotor. A receiving groove(31) for the blade unit is formed at one side of the outer surface of the rotor. The width of the blade unit is 0.2-0.3 times of the maximum protruding length of the vane.;COPYRIGHT KIPO 2013
