<p>PURPOSE:To improve operation efficiency without weakening the strength of a movable scroll by forming the inside end section of No.2 spiral body in such a way as to be gradually thinned toward its tip end while being tapered. CONSTITUTION:The inside end 25 of No.2 spiral body 10 is formed in such a way as to let the inner circumferential surface 26 of it be gradually thinned toward its tip end while being tapered with the anglo theta used. The spiral body 10 on the side of No.2 movable scroll 9 is formed into a tapered one, the base end section of which is thereby thicker than its tip end in such a way as to be strengthened so that it shall sufficiently withstand excessive pressure applied when fluid is compressed and the like.</p> |
