Abstract: A valve system for an internal combustion engine includes a valve member having a head and a stem extending from the head, the head being capable of forming a seal with a valve seat of the internal combustion engine and the stem having at least one cylinder in an end portion thereof, and a component for contacting a portion of a rocker arm of the engine, the component being movable in the cylinder between a first position and a second position closer to the rocker arm than the first position. Structure is provided for moving the component between the first position and the second position to change lift of the valve member. The system adjusts valve lift according to speed of the engine to improve combustion efficiency.
