  • Entrapped separator plate for scroll compressor
    Patent number: 6203298
    Abstract: A scroll compressor assembly incorporates a separator plate which has a clearance between its outer periphery and an inner periphery of an end cap. In this way, the location of the separator plate along the center axis of the scroll can be adjusted. Further, the separator plate is placed on the center shell prior to attachment of the end cap. Thus, the separator plate need not be welded to the end cap as in the prior art. Problems such as weld splatter thus eliminated.

  • Twin cylinder rotary compressor
    Patent number: 5542831
    Abstract: A separator plate is provided in the pump cartridge assembly of a twin cylinder rotary compressor. The separator plate separates and coacts with other structure to define two distinct compression/suction chambers. Because there is only one correct assembly orientation, it provides automatic alignment of the two pump subassemblies making up the pump cartridge.

  • Sound abatement in rotary compressors
    Patent number: 5246356
    Abstract: The crankcase or cylinder body of a rotary compressor is secured in a shell by a shrink fit thereby providing intimate contact over its entire circumference. To maintain the proper positioning of the crankcase during the shrink fitting process, the outer surface of the crankcase defines a portion of a sphere, specifically the equatorial portion. As a result the spherical surface provides a stable contact surface over a range of positions of the crankcase and the intimate contact changes the frequencies of response of the shell.
