Abstract
Scroll compressors ( ) may include a movable scroll ( ) that is disposed opposite to a fixed scroll ( ). At least one compression chamber ( ) is defined between the fixed scroll and the movable scroll. A motor ( ) drives the movable scroll, so that the movable scroll revolves (orbits) relative to the fixed scroll. The movable scroll includes a front portion ( ) that slidably contacts the fixed scroll. The front portion receives the pressure of the pressurized refrigerant that is disposed within the compression chamber. The movable scroll also includes a rear portion ( ) that slidably contacts a portion ( ) of a compressor housing. The motor is disposed within a motor chamber ( ) defined within the compressor housing. A first conduct route ( ) communicates discharged refrigerant from a discharge-side region ( ) to the motor chamber. A second conduct route ( CL) communicates refrigerant from the motor chamber to a suction-side region ( ), thereby adjusting the pressure within the motor chamber, so that the opposing pressing forces applied against both sides to the movable scroll can be appropriately adjusted in order to improve compressor efficiency.
