ABSTRACT:
A scroll-type fluid machine such as a scroll compressor or a scroll vacuum pump generates compression heat during compressing operation. A scroll body comprises a stationary scroll and an orbiting scroll that is revolved with respect to the stationary scroll eccentrically. The stationary scroll has a stationary wrap and the orbiting scroll has an orbiting wrap engaged with the stationary wrap to form a compression chamber therebetween. In the scroll-type fluid machine, a cooler is provided to cool high-temperature compressed air discharged from a discharge bore at the center of the stationary scroll.
