Abstract
This application provides a screw compressor and a slide valve thereof. The slide valve includes: a valve body having a cylindrical shape extending in an axial direction, with a side surface having a pressure discharge surface that matches an outer peripheral contour of a rotor of the screw compressor; a discharge chamber provided at an end of the pressure discharge surface along the axial direction; a slider provided in the discharge chamber, and configured to slide along a radial direction of the valve body, a shape of an outer edge of the slider matching a shape of the pressure discharge surface; and a spring connected to the slider and configured to drive the slider to slide to a position where the outer edge of the slider is flush with the pressure discharge surface.
