ABSTRACT:
A power aggregate comprising a two-stroke engine, a piston rigidly linked together by means of a piston rod, a plurality of pump cylinders circumferentially mounted around the piston rod and a corresponding number of pump pistons fixed to the piston rod through the intermediary of radial rods or a flange, for reciprocation within the pump cylinders. Each pump cylinder is provided with hydraulic fluid intake and pressure ducts, and at least two of the pump cylinders have different diameters. The hydraulic duct of one or several pump cylinders operates its own hydraulic motor or actuator cylinder.
