Abstract
Mechanical controls for continuously varying the length of the stroke of the valves in an internal-combustion engine and for maintaining the valves constantly closed while the engine is in operation while simultaneously varying how long the valve or valves remain open, whereby the valves are actuated by rocker levers that are in turn actuated by an angled lever, whereby the positions of the levers are varied in order to vary the length and duration of the stroke. The valves are actuated at low engine speeds by assigning a specific narrow angle of rotation to each abbreviated stroke to be established. FIG.illustrates valve stroke controls with an angled lever () actuated by a cam () mounted on a lateral roller (). In the event of a misalignment, a planetary gear comes into play, wherein a roller (), mounted on the rocker lever () that actuates the valve () acts a sun wheel, the angled lever () acts as a planet wheel, and a setting lever () acts as a planet bearing.
