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, mechanisms are 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, and for compensating for the thermal conditions of the engine causes valve stem elongation and contraction.

Abstract: A wheel transmission for mobility vehicle includes an input component capable movement at a first rate of motion for selectively driving an output component at either the first rate of motion or a second rate of motion. Operably connected between the input component and the output component is a conversion apparatus which enables the selective drive between the input component and the output component to take place. In addition, the conversion apparatus is capable of preventing the output component from being backdrivable, and thereby acting as a brake, when the vehicle is at rest.
