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).
La présente invention concerne un compresseur à vis à injection d'eau, comprenant un élément de compresseur (2) présentant un logement (7) qui entoure une chambre de compression (8) dans laquelle deux rotors (9, 10) sont installés, lesquels, au moyen de portées de tourillons (13, 14; 15, 16), sont disposés dans le logement (7) au moyen de paliers lisses (1) lubrifiés par eau, un moteur électrique (3) comprenant un logement (18) qui porte un stator (19) à l'intérieur, lequel stator entoure un rotor (21) avec un arbre rotor (22). Une portée de tourillon (13) de l'un des rotors (9) est directement couplée à l'arbre rotor (22) ou forme une pièce avec l'arbre rotor (22) du moteur (3), ledit arbre rotor étant situé dans le prolongement de ladite portée de tourillon. L'arbre rotor (22) du moteur (3) est disposé dans au moins un palier lisse (23) lubrifié par eau.
