ABSTRACT:
Previous compressors have employed compressors to compress and circulate refrigerant through a circuit, and have been unable to combine the differing advantages of rotary compressors, scroll compressors and screw compressors. The present invention combines these advantages, as well as inhibiting refrigerant leakage and improving overall performance, by particularly fixing the position of the compression member of the compression element relative to the driving element. The driving element is stored in a sealed container of the compressor. The compression element includes a cylinder having suction and discharge ports and a compression member which compresses a fluid (refrigerant) sucked from the suction port to discharge the fluid via the discharge port; and a vane partitioning the compression space in the cylinder into a low pressure chamber and a high pressure chamber.
