the rotating of the bladed rotor 24 triggers circumferential circulation of the liquid in the hydraulic chamber 12 the inlet 13 and the outlet 14 the hydraulic chamber 12 is closed by an axial joint 25 placed in the body 2 between the motor 22 and the rotor 24 the motor 22 outlet shaft 23 passing through the joint 25 in a sufficiently liquid tight way when the pump 1 is activated the liquid is sucked through the inlet opening 5 goes up the duct 6 and then goes into the hydraulic chamber 12 through the inlet 13 the rotation of the rotor 24 blades triggers the discharge of liquid through the two outlets 14 and from there through the two outlet ducts 15 the liquid then arrives in the distribution chamber 18 which it fills at least partially and is simultaneously expelled through the two outlet openings 19 and the two outlet tips 10 with an acceptable difference in outflow between the two outlets 10 at standard pressures according to one embodiment the pump 1 according to the invention operates at relatively low pressures of the order of 1 10 5 to 3 10 5 pascals an interference suppression system 26 can be provided in the protecting housing 8 to improve the operation of the pump 1 when used in automobiles according to the embodiment the body 2 of the pump.
