Abstract
A single screw compressor comprises a main rotor and at least one gate rotor, a casing for the main rotor having a discharge port at a discharge end of the casing, and a slide slidable within a bore in the casing adjacent the main rotor. The slide has a cut-out () between first () and second () sealing parts of the slide, the slide is slidable between a high volume ratio position where the cut-out () is within the casing and provides a path to the discharge port, and a low volume ratio position where the slide is beyond the discharge end of the casing to provide a fixed discharge path in the bore of the casing.
