Abstract
A scroll fluid machine includes stationary scrolls, with embedded wraps which are spiral in form, extending from central parts of scroll bodies toward the outer peripheries thereof, and a revolving scroll, with an embedded spiral wrap, engaging with the spiral wraps. The revolving scroll has a scroll body coupled to a drive shaft coupled to a drive at the central portion thereof. The drive shaft is cooled directly by a cooling structure 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.
