ABSTRACT:
Cooling means are provided for the stationary and orbiting scroll members of scroll-type apparatus. These cooling means comprise fluid coolant channels in the end plates and in the involute wraps of the scroll members and means to circulate a fluid coolant therethrough. In the case of the stationary scroll member the coolant may be water, oil or the like; while in the case of the orbiting scroll member the coolant is the lubricating oil used to lubricate a thrust bearing and the coupling means. The resulting effective cooling of the scroll members makes it possible to form scroll apparatus in large sizes.
