摘要： The invention concerns an element of a screw compressor injected with water containing two rotors (2-3) in a rotor chamber (4). The water circuit (11) contains a part (10) in which practically prevails the outlet pressure. On the inlet side, the axle journals (13, 16) are radially supported on hydrodynamic slide bearings (18, 19). In the housing (1) opposite to the crosscut ends of the axle journals (13, 16) are formed chambers (20, 21) which are connected to the above-mentioned part (10) or to the inside of the rotor chamber (4). On the outlet side, the axle journals (14, 17) are radially supported on hydrodynamic slide bearings (25, 26) on the one hand, and they are axially supported on hydrostatic slide bearings (27, 28) on the other hand which are connected to the above-mentioned part (10) of the water circuit (11), or on hydrodynamic slide bearings (37, 38).

摘要： 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).
