Abstract
A scroll compressor (10) comprising a stationary scroll member (12) including an end plate (14) and a stationary involute wrap (16) extending from the end plate (14), and a discharge port (18) defined within the end plate (14). The scroll compressor (10) has an orbiting scroll member (20) including an orbiting involute wrap (16) which is movable in cooperative relationship with the stationary involute wrap scroll (12) so that a pair of sealed pockets (26, 28) is formed therebetween, the volume of the sealed pockets (26, 28) being reduced as orbital motion progresses. A relief port (32) extends through the end plate (14), in communication with one of the sealed pockets (26, 28) and a suction chamber so that at any given point of orbital motion, there is a pressure imbalance between pockets in the pair of sealed pockets (26, 28), and a consequent diminution in noise and vibration of the scroll compressor (10).
