ABSTRACT:
In an apparatus for altering the valve timing of an internal combustion engine as a function of load and rotational speed, a helical pinion is mounted so as to be axially displaceably, but non-rotatably mounted on the camshaft. The pinion is in engagement with an axially fixed helical intermediate gear-wheel driven by the crankshaft. The helical pinion is connected to the camshaft by a splined connection and has tracks for a radial ball bearing, one of which is formed on a sleeve which is guided axially displaceably, but non-rotatably in a part of the camshaft housing by way of a key and keyway connection. The sleeve has a toothed rack portion which is in engagement with an actuating pinion which is driven by an actuating drive controled by a sensor sensing the operating parameters of the engine.
