SCROLL COMPRESSOR, CAPABLE OF PREVENTING REFRIGERANT IN A DISCHARGE SPACE FROM FLOWING BACKWARD AT THE BEGINNING POINT OF DISCHARGING

摘要

PURPOSE: A scroll compressor is provided to prevent the noise generation of a compressor by effectively preventing refrigerant in a discharge space from flowing backward into a compressing chamber without installing a separate check valve.;CONSTITUTION: A scroll compressor comprises a fixed scroll, a rotary scroll(140), a rotary shaft, a drive unit, and a cut-out unit(172). The rotary scroll is engaged with a fixed lap and is equipped with a rotary lap which is formed with first and second compressing chambers on the outer and inner circumferences. The rotary scroll is equipped with an outlet(148) for discharging compressed refrigerant from the first and second compressing chambers. The rotary shaft is equipped with an eccentric unit in one end and is coupled with the rotary shaft in order to overlap the eccentric unit and rotary lap in the radial direction. The cut-out unit is capable of partially covering the rotation route of the outlet.;COPYRIGHT KIPO 2013
