A screw compressor having two rotors (2,3) rotatably journalled for mutual meshing engagement in a respective working chamber (4,5) of a compressor housing (1). For the purpose of regulating the pressure ratio and the capacity of the compressor, a composite slide assembly comprising two slides (17,18) is mounted for axial movement in a recess (6) in the housing (1), the composite slide having two flanks which form a continuous wall in the two working chambers (4,5). The two slides are individually movable and, for the purpose of improving the regulating function one of the slides (18) is provided with a flank which forms a wall of the working chamber (4) of solely one rotor, preferably the male rotor (2). |
