Abstract:
A desmodromic valve actuation system for opening and closing at least one valve of an engine having a cam assemblage and a driving mechanism for reciprocal movement operably connected to said cam assemblage. The cam assemblage includes a cam mechanism for rotational movement and the driving mechanism also being operably connected to the at least one valve of the engine to move the at least one valve between a valve closed position and a valve open position and between the open position and the closed position in a manner directly related to the rotational movement of the cam mechanism. In addition, a mechanism is provided for adjustably controlling the movement of the at least one valve in order to provide a variable amount of opening of the at least one valve in the open position. The opening and closing of the at least one valve takes place without the intervention of a spring action.
