ABSTRACT:
The invention relates to a water-injected screw compressor, comprising a compressor element (2) with a housing (7) which borders a compression chamber (8) in which two rotors (9, 10) are installed, which, by means of an axle ends (13, 14; 15, 16), are borne in the housing (7) by means of water-lubricated slide bearings (1), an electric motor (3) comprising a housing (18) which carries a stator (19) at the inside, which stator surrounds a rotor (21) with a rotor shaft (22). An axle end (13) of one of the rotors (9) is directly coupled to or forms one piece with the rotor shaft (22) of the motor (3), said rotor shaft being located in the prolongation of said axle end. The rotor shaft (22) of the motor (3) is borne in at least one water-lubricated slide bearing (23).
