Abstract

A screw compressor includes: a screw rotor having a discharge-side end surface; a casing having a rotor facing surface facing the discharge-side end surface, and an opening disposed on the rotor facing surface and communicating with a discharge space into which a gas compressed by the screw rotor is to be discharged; a slide valve whose position in an axial direction of the screw rotor is variable so as to change an internal volume ratio; and a movable piece disposed along an edge of the opening of the casing and configured to be capable of blocking a part of the opening. The movable piece is configured to be movable between a first position where the movable piece forms a first contour of an axial discharge port together with the edge of the opening, and a second position farther away from the screw rotor in the axial direction than the first position. The screw compressor is configured such that when the movable piece is located at the second position, a second contour of the axial discharge port having an opening area larger than that of the first contour is formed by the opening.
