Abstract (en)
A scroll fluid machine comprises stationary and orbiting scrolls 1,2. The orbiting scroll 2 is revolved by a driving shaft 21 with respect to the stationary scroll 1 to crease an inner expanding region. Fluid from the inner expanding region flows to the rear side of an orbiting end plate 2' of the orbiting scroll 2. An expanding cover 120 is mounted to the orbiting end plate 2' to create a narrower space 124 between a boss 4 of the orbiting end plate 2' and an inward-projecting portion 123 of the expanding cover 120. Fluid from the expanding region flows through the narrower space 124 and is depressurized or cooled. The cooled fluid cools the boss 4.
