Abstract

The present invention relates to a screw compressor primarily for gaseous refrigerants, which screw compressor comprises a compressor housing (4), which comprises a male (8) and a female (10) screw rotor arranged in screw rotor bores (6) in the compressor housing(4), which male and female rotor are co-rotatingly driveable and interact to compress the refrigerant, where the compressor housing (4) is connected to a bearing housing (14), where rotor endplates (16,18) are placed between the screw rotors and the bearing housing, which rotor endplates comprise cutouts for discharge ports. The endplates (16,18) comprise outer diameters, which respective diameters significantly exceed the corresponding rotor diameters which outer diameter of the endplates (16,18) cooperates with recesses in the compressor housing (4) and with recesses in the bearing housing (14).
