Abstract (en)

[origin: EP1462647A2] The hydraulic machine has a casing (1) containing a rotating cylinder block (11) in a rotor (10) of an electric motor. The stator (9) of the motor is fastened to the inside surface of the housing. The machine is used for pumping fluid. As the rotor turns, the working pistons (13) are made to reciprocate in their cylinders (12) by a tilting plate (14) fixed to the housing. Hydraulic pistons (22,26) are connected to control members (28,33) to adjust the tilt of the plate defining the stroke of the working pistons. There is a tilt measurement device (27) for the tilting plate and a pressure sensor (20) for the high-pressure output from the working cylinders.
