Beschreibung
Zusammenfassung:	The invention relates to a variable valve train for switching an outlet valve of an internal combustion engine to an engine braking mode. The variable valve train has a camshaft with a first cam, which is designed as a normal operation cam, and a second cam, which is designed as an engine braking cam. A first rocking lever has a first stroke device which is designed for selectively making or breaking a first operative connection between the first cam and the outlet valve by means of the first rocking lever. A second rocking lever has a second stroke device which is designed for selectively making or breaking a second operative connection between the second cam and the outlet valve by means of the second rocking lever. A valve device selectively connects the first stroke device or the second stroke device to a fluid feed line.
