PURPOSE:To improve the efficiency of compressor by forming a groove at the tip of a spiral body then fitting a U-shaped resilient board in the groove thereafter feeding pressure into the groove to push up the board from the back and enclosing the scroll compressor axially. CONSTITUTION:A groove 6 is formed at the tip of a spiral body 5 in a rolling scroll 2 facing with a fixed scroll 1 to fit an U-shaped resilient board 9 into the groove. When fitting, the high pressure end of the bent board 9 is opened while the low pressure end is enclosed. Upon operation of scroll, compressed high pressure gas will intrude through the high pressure open end of the bent board 9 into the groove 6, to contact said board 9 tightly with the fixed scroll 1 thus to seal the gap between both scrolls tightly. |
