ABSTRACT:
An apparatus for adjusting the stroke of a valve that is actuated by a camshaft having at least one cam is provided. A valve lever having an outer lever and an inner lever is provided and has a first end region supported on a fixed component, and a second end region for actuating a valve. The U-shaped outer lever includes two arms and a crosspiece that faces the fixed component. At least one of the arms is provided with an abutment surface for contacting the at least one cam. The inner lever is mounted on a free end of the outer lever between the arms, and has an abutment surface, for contacting cams, that is disposed between the mounting axis of the inner lever on the arms and the support of the first end region of the valve lever on the fixed component. A blocking device is provided for fixing the crosspiece of the outer lever on an end of the inner lever remote from the valve, this end being supported on the fixed component and containing the blocking device.
