ABSTRACT:
An arrangement for interrupting the flow of force between a camshaft and a valve in the valve gear of an internal combustion piston engine comprises a camshaft with a cam, a rocking lever which is mounted fixedly with respect to the engine casing and the rocking movement of which is actuated by the cam and an actuating member mounted on the rocking lever and guided on the rocking lever movably relative thereto, for actuation of the valve. A movable coupling member is mounted on the rocking lever and is movable by means of an actuating device into a first position in which for actuation of the valve it provides a rigid connection between the rocking lever and the actuating member and into a second position in which the actuating member is movable relative to the rocking lever so that actuation of the valve is interrupted.
