Abstract (en)
A screw compressor includes a casing including a discharge port, a screw rotor accommodated in the casing, the screw rotor having one end side serving as a suction side in an axial direction, and an other end side serving as a discharge side in an axial direction, and a slide valve accommodated in a slide-valve accommodating groove formed in the casing, the slide valve being slidable in a rotational axis direction of the screw rotor. The slide valve includes a valve body portion. The slide valve moves to a position where the valve body portion faces the screw rotor and to a position where the valve body portion does not face the screw rotor. The valve body portion forms a portion of the discharge port when in a position facing the screw rotor.
