Abstract
In a valve train device, particularly of an internal combustion engine, which device has an actuating device for displacing at least one axially displaceable cam element and a gear shifting gate for axially displacing the cam element and furthermore at least one switch unit with a switch element and an actuator for operating the switch element so as to engage the gear shifting gate at least in one switching position and to move the switch element into a desired switching position, the gear shifting gate has at least one intermediate segment for terminating a switching action.

A valve drive train device, in particular of an internal combustion engine, including at least one axially displaceable cam element (11, 12, 11a, 12a, 11b, 12b) an actuation device (10, 10a;
- 10b), for moving the at least one axially displaceable cam element (11, 12, 11a, 12a;
- 11b, 12b), a gear shifting gate (13a, 13b;
- 16) for displacing the cam element (11, 12, 11a, 12a;
- 11b, 12b) and at least one switch unit (13, 18, 22a, 23a) with a switch element (14, 19, 20a) and an actuator (15, 17, 55a) for engaging the gear shifting gate (13a;
- 13b, 16) at least in one switching position, with the actuator (15, 17, 55a) being provided for moving the switch element (14, 19, 20a) into the switching position, the gear shifting gate (13a;
- 13b, 16) having at least one intermediate segment (14a-19a;
- 14b, 15b, 52-57) for terminating a switching action.
