Abstract
A scroll type compressor including mutually mating stationary and movable scrolls for producing compression. A circumferentially outer part of the movable scroll portion has a flat end surface and a chamferred surface. The chamferred surface tapers outwardly at an angle relative to the flat end surface greater than an allowable tilt angle of the movable scroll. A circumferentially inner part of the scroll portion includes a flat end surface only which has a groove to receive a tip seal, the tip seal having a height greater than a depth of the groove. The circumferentially outer part has an identical outer diameter to that of the base plate portion, and the base plate portion and the scroll portion are simultaneously machined.
