Hydro-electric power unit for variable distribution thermal engine, has pumps whose pistons are controlled by shaft, where cams, shaft and connecting rods circulate oil between rotating hydraulic cylinders and unit

摘要

The unit has pumps whose pistons (6) are controlled by a shaft (25). Cams (2), the shaft and connecting rods circulate oil between rotating hydraulic cylinders and the unit, where the hydraulic cylinders are arranged outside the unit. The pistons move in stepped jackets (7) that are immobilized in rotation by fingers (9). The fingers move perpendicular to a toothed rack (16) and pinion-nuts, where displacement of the toothed rack and a helicoid sleeve (24) is controlled by a hydraulic actuating cylinder or an electric device that is operated by probes.
