SCROLL TYPE FLUID MACHINE

摘要

The present invention provides a scroll type fluid machine which determines the position of an orbiting scroll member and a rear plate with high precision and installs a sealing member for through holes to increase the compression efficiency and the reliability of the fluid machine. For the purpose, the present invention includes: a fixing scroll; an orbiting scroll member which is installed to face the fixing scroll and forms a plurality of compression chambers between the orbiting scroll member and the fixing scroll to move in an orbiting motion; a driving shaft driving the orbiting scroll member; and a rear plate which is installed between the orbiting scroll member and the driving shaft. Position alignment holes are formed on the orbiting scroll member and on the rear plate. Position alignment pins and sealing member for sealing the compression chambers are installed on the position alignment holes.
