Abstract

See full text

The invention relates to a valve drive assembly for an internal combustion engine. The aim of the invention is to improve the assembly in such a manner that a stationary cam can be reliably connected to a cam that is rotatably mounted on the camshaft and to avoid malfunctions. For this purpose, a groove-type guide is arranged in the area of the base circle of the cam which is rotatably mounted on the camshaft. A pilot locking plunger is mounted in a blind bore of the base circle of the cam that is connected to the camshaft so as to rotate with it. The plunger can be displaced in a controlled manner and can be engaged with the guide disengaged therefrom. The groove-type guide in which the pilot locking plunger engages extends in the base circle of the rotatably mounted cam by approximately 180°.
