Abstract
A screw compressor with a volume ratio adjustment mechanism. The volume adjustment mechanism is a penetration in the housing of a screw compressor. The penetration includes one or more apertures. The apertures provide a flow path between the compressor outlet and an interlobe region of the screw compressor rotors. A member resides in the penetration and is movable from a first position in which the apertures are blocked and the flow path is closed and a second position in which the apertures are not blocked and the flow path is open. By unblocking the apertures and opening the flow path, the volume ratio can be adjusted.
