Abstract

A screw compressor comprises two screw rotors arranged in a screw rotor chamber, and mounted on the compressor housing to be rotatable about respective screw rotor axes, and mesh with one another. At least one control slide is arranged in a slide channel of the compressor housing, adjacently to both screw rotors by means of slide compression wall surfaces, is movable in a displacement direction parallel to the screw rotor axes, is rigidly connected to a piston rod that leads to a cylinder assembly for moving the at least one control slide, and is guided relative to the compressor housing by means of a guide insert that movably receives the piston rod in the displacement direction. The piston rod is guided transversely to the displacement direction in the guide insert in elastically resilient fashion by means of a guide element.
