  • Self-sealing scroll compressor
    Patent number: 5252046
    Abstract: A scroll type compressor comprising a housing inside which a stationary scroll member and a frame are fixed to define a space therebetween large enough to receive therein an orbiting scroll member which inter-engages with the stationary scroll member to define therebetween a hermetical compression pocket into which the fluid to be compressed fills. An Oldham-coupling ring restricts the orbiting scroll member to orbit around the center of the stationary scroll wrap only. A back pressure chamber is in pressure connection with the compressed fluid through a lubricant for the compressor and also in fluid connection with an inlet of the fluid to be compressed through a capillary-like passage.
