SCROLL COMPRESSOR PREVENTING THE EXCESSIVE INCREASE OF COOLING CAPACITY OCCURRING ACCORDING TO INCREASES OF A SCROLL COMPRESSOR SPEED AND HAVING THE SIMPLE STRUCTURE

摘要

PURPOSE: A scroll compressor is provided to reduce volumetric efficiency of the scroll compressor by inducing the refrigerant inside a compression room and to reduce cooling efficiency of an air conditioner.;CONSTITUTION: A scroll compressor comprises a rotating scroll member (24), a driving device accommodating space, a rotary shaft (14), a driving bushing (20), a top space (29), a lower space (51), a first communicating path (48), and a second communicating path. The top space and the lower space are formed by a plain bearing, the driving bushing, and an eccentric pin (19) of the rotary shaft. The second communicating path passes through the driving bushing and connects the top space and the lower space. A control valve is arranged in the second communicating path. When the rotary shaft is rotated at a speed in which is greater than a predetermined speed, the centrifugal force of a control valve is generated and the control valve is moved in an opening direction of the second communicating path so that the top space and the lower space are connected.;COPYRIGHT KIPO 2013
