摘要

PROBLEM TO BE SOLVED: To provide a fluid machine improving expanding performance by improving a sealing property of a scroll outer peripheral portion, and suppressing increase in size and weight of the whole of a pump. SOLUTION: A fixed side chip seal (a sealing member) 112 installed along a tip end side end surface of a fixed side scroll lap (a tooth portion) 102b of a fixed scroll 102 is provided so as to extend till a position generally matching with an inside winding finish portion A of the fixed side scroll lap 102b. The outer shape of a slewing side end plate portion 103a is expanded so as to make the whole sliding surface of the fixed side chip seal 112 abut on the slewing side end plate portion 103a even if a slewing scroll 103 revolves. Therefore, the expanding performance can be improved by improving the sealing property of the scroll outer peripheral portion. COPYRIGHT: (C)2006,JPO&NCIPI
