Abstract
A scroll compressor in which each of its stationary and swivel scrolls has at least one recess formed in the inner surface of its wrap adjacent to an area of wrap engagement or disengagement. The recess has an inclined edge extending at an angle to the end plate upon which each lap stands upright. The recess enables the wraps to have gradually changing lines of contact with each other along their heights to prevent undesirable noise or vibration during their engagement or disengagement.
