Abstract
In a valve drive train device, particularly of an internal combustion engine, having an actuating device provided to displace at least one first axially displaceable cam element using a shifting gate, the actuating device is designed for switching the axially displaceable first cam element into the various switching positions.
Claims10
A valve drive train device, in particular of an internal combustion engine, including at least one axially displaceable first cam element (11a, 11b) provided with a shift gate (13a, 13b), and an actuating device (10a, 10b) for displacing the at least one axially displaceable first cam element (11a, 11b) by means of the shift gate (13a;
- 13b) to at least three switching positions, the shift gate (13a;
- 13b) having at least two switch segments (14a, 16a, 18a, 20a;
- 14b, 16b, 18b, 20b) for displacing the first cam element (11a;
- 11b) in a switching direction.
A method for operating a valve drive train device in particular of an internal combustion engine, including at least one axially displaceable first cam element (11a, 11b) provided with a shift gate (13a, 13b), and an actuating device (10a;
- 10b) for displacing the at least one axially displaceable first cam element (11a;
- 11b) by means of the shifting gate (13a;
- 13b) into at least three switching positions, the shift gate (13a;
- 13b) having at least two switch segments (14a, 16a, 18a, 20a;
- 14b, 16b, 18b, 20b) for displacing the first cam element (11a;
- 11b) in a switching direction, an actuating device (10a;
- 10b), which is provided to displace at least the first axially displaceable cam element (11a;
- 11b) by means of a shift gate (13a;
- 13b), said method comprising the step of operating the actuating device (10a;
- 10b) for switching the cam element (11a;
- 11b) into one of the at least three switching positions.
