Scroll compressor including a plurality of shoulder sections

摘要

Provided is a scroll compressor that is capable of three-dimensional compression, ensuring a required wrap strength while increasing a shoulder section height of a spiral wrap, and facilitating wrap processing. The scroll compressor includes shoulder sections at an end surface and a bottom surface of spiral wraps of a paired fixed scroll member and revolving scroll member and configured to be capable of three-dimensional compression in a circumferential direction and a height direction of the spiral wraps by setting a spiral wrap height of the spiral wraps further toward the outside of the shoulder sections greater than the spiral wrap height of the inward side, and wherein the shoulder sections provided on the end surface and the bottom surface at the spiral wrap are constructed of a plurality of shoulder sections, and the heights of the shoulder sections are set to heights in which base stresses at the shoulder sections are substantially equal.
