Compressor for a motor-compressor set, comprising, on a rotating shaft (2), a balancing piston (7), a set of bladed wheels (R), a rear cavity (11) of the piston adjacent to the balancing piston (7) on a side opposite to the set of bladed wheels (R), a regulation valve (14) suitable for coupling the rear cavity (11) to the input of the set of bladed wheels (R), a suction pressure chamber (20) coupled to the input of the set of bladed wheels (R), the rear cavity (11) being arranged between the balancing piston (7) and the suction pressure chamber (20). The compressor comprises a discharge pressure chamber (18) arranged between the rear cavity (11) of the piston and the suction pressure chamber (20), the discharge pressure chamber (18) being coupled via a discharge line (19) to a discharge area (10) situated between the set of bladed wheels (R) and the balancing piston (7). |
