Regulating hydraulic drive of valves for timing gear, finding its application in engines with internal combustions consists of two cams (1) with evenly changeable along their length profiles and attached to an axially-mobile shaft (2) and cooperating, in space full with working fluid, with pistons (3) of radially and symetrically placed around them guiding hydraulic cylinders of the valves, via freely rotating around their centers spheres (4), attached to them. Each couple of profiles for cooperation, defined by the level of the axial displacement of the cams (1) is providing the most suitable timing gear for a defined rotation frequency of the engine. The shaft (2) is connected at the one of its ends to a middle shaft (13) via spline joint (14), supplied with centrifugal regulator (15) and a repelling spring (16) and at the other end exists a unit for correction and connection to the fuel supply and spark supply in the cylinders of the engine according to the rotation frequency. |
