ABSTRACT:
A scroll-type compressor having a capacity modulation system of the delayed suction type is disclosed which incorporates a valving ring rotatably supported on one of the scroll members. Seals are provided acting between the valving ring and scroll member which serve to effect a fluid tight sealing relationship therebetween when the compressor is operating in a full capacity mode thus reducing the need for maintaining tight tolerances during manufacture of the valving ring.
