摘要:
A scroll-type compressor whose capacity can be easily changed and with which an inconvenience can be prevented is provided. A scroll-type compressor includes a fixed scroll having a first spiral-shaped wall member provided upright on a side surface of a first end plate, and an orbiting scroll having a second spiral-shaped wall member provided upright on a side surface of the second end plate, the orbiting scroll being supported so as to be capable of orbital revolution movement while being prevented from self rotation by meshing the wall members with each other. Wall-member stepped portions having a small height at the center and a large height at the outer side in a direction along the spiral are formed on the upper edges of the first and second wall members. End-plate height-difference portions having a large height at the center and a small height at the outer side in the direction along the spiral are formed on the side surfaces of the first and second end plates, at positions facing the wall-member stepped portions. One of the first and second wall members has a cutout portion formed at the outer end in the direction along the spiral and has a smaller spiral-end angle than the other of the first and second wall members.
