Abstract
A scroll fluid machine is disclosed, which comprises a stationary scroll with an embedded wrap which is spiral in form, extending from a central part of a scroll body toward the outer periphery thereof, and a revolving scroll with an embedded spiral wrap engaging with said spiral wrap, the said revolving scroll having a scroll body coupled to a drive shaft,A coupled to a drive at the central portion thereof. The drive shaft,A is cooled directly by cooing means provided inside it. The scroll body of the revolving scroll has a central part coupled to a drive. Heat generated in a process, in which fluid sucked from the scroll edge is led to the central part while being progressively compressed, can be removed at the central part which is elevated to a highest temperature, thus permitting efficient cooling of bearings and seal members near the revolving scroll central part and the drive shaft.
