SUBSTANCE: invention relates to screw compressor. Compressor comprises housing with chamber in it, two screw rotors arranged in chamber, which with their screw circuits enter into each other and interact with adjacent to them and partially enclosing their sealing wall surfaces, at least one distributing slide valve located in slide valve channel of housing and adjoining sealing wall surfaces of slide valve to both screw rotors. Slide valve is movable in direction of displacement parallel to screw rotor axes. Slide valve is rigidly connected to the piston rod, which leads to the cylindrical structure for movement of at least one distribution slide valve and which by means of the piston rod moving in the direction of the guide insert movement is directed relative to the housing. In the guide insert, the piston rod is elastically pliable by means of the guide element across the direction of movement.
