Scroll type compressor in which a sealing is improved between scroll members

摘要

In a scroll type compressor in which bottom plates (2, 3) are disposed on bottoms of involute grooves formed on scroll members (20, 30), respectively, each of the bottom plates has a thickness becoming gradually larger from an outer circumferential portion of each of the involute grooves towards a central portion thereof. The scroll members confront with each other in an axial direction with each of the bottom plates being interposed between the scroll members in the axial direction.
