Abstract
The invention relates to a valve-actuating device for actuating a valve of a reciprocating piston engine, comprising a first and second rocker arm rotatably mounted about a common rotational axis; a pushrod connected to the first rocker arm so as to transmit an actuating movement of the first rocker arm to a valve; a first and second cam arranged on a shaft, where the first rocker arm marks a contour of the first cam and the second rocker arm marks a contour of the second cam, where the rocker arms are connected together via a mechanical coupling apparatus having a locking element able to be brought into at least a first position and a second position and configured to transmit an actuating movement of the second rocker arm to the first rocker arm at least in the first position of the locking element; and a switching device having a slotted guide element which is designed to bring the locking element of the coupling apparatus at least from the first position to the second position and vice-versa.
