    摘要: The machine comprises first and second screw rotors (1, 2) supported by bearings (47) in a stator casing (3) which is provided with a suction inlet and a delivery outlet, the first rotor is driven by a motor (10) and the second rotor is driven by means of synchronizing gearing (11-12) situated in a first chamber (14) of the casing and located between the motor (10) and one of the ends of the rotors, the gearing (11-12) running in a lubricating fluid (15), the machine is characterized in that the cavity (30) of the casing containing the rotors (1-2) is separated from the first chamber (14) by a first wall (16) having the shafts (8, 13) of the rotors passing therethrough via seals (17-18), in that the shafts of the rotors at the opposite ends of the rotors to the ends having the gearing pass through a second wall (20) via seals (24-25), and in that the casing (3 ) includes, beyond the second wall (20), a second chamber (31) connected to the first chamber (14) by a main pipe (29) provided with pumping means (49), the rotors and the stator-casing including fluid circulation channels (32 to 34) terminating firstly in the second chamber (31) and secondly in the first chamber (14) and/or in that portion of the pipe (29) lying between the first chamber (14) and the pumping means, with a heat exchanger (41) being disposed on the path of the pipe (29).
