ABSTRACT:
Engine valve driving apparatus having a camshaft and a radially movable cam supported on the camshaft. A support is fixed to the camshaft. Both the movable cam and the fixed support are formed with holes, whose axes coincide with each other when the movable cam protrudes at its maximum outward position. A connecting pin is disposed in the hole of the fixed support and an oil supply actuates the connecting pin. When the connecting pin is forced by the oil supply, the connecting pin lifts the movable cam radially outwardly to its maximum outward position.
