Abstract
A scroll-type compressor has a liquid injection system for injecting liquid into an enclosed space defined by first and second scroll members which engage in cyclical relative orbiting motion, to reduce the temperature of the working fluid. The compressor incorporates a discharge diffuser for reducing the pressure of the working fluid in an enclosed space, so that the liquid may be injected into the enclosed space from a more centrally located injection port than one which would allow liquid injection without the discharge diffuser.
