The invention relates to a power aggregate, wherein pistons (2) of a two-stroke engine are rigidly linked together by means of a piston rod (6). A plurality of pump cylinders (5) are circumferentially mounted around piston rod (6) and pump pistons (4) are fixed to the piston rod through the intermediary of radial rods or a flange (4a). Each cylinder (5) is provided with hydraulic fluid intake and pressure ducts (9, 10). The hydraulic duct of one or several cylinders (5) operates its own hydraulic motor or actuator cylinder. |
