Abstract:
A valve drive for an internal combustion engine may include a cam shaft, a cam follower, and an adjusting device. The cam shaft may include at least one first cam and at least one second cam. The cam follower may be drivingly connected to the at least one first cam when in a first position and drivingly connected to the at least one second cam when in a second position. The adjusting device may include a first engagement element configured to cooperate with a first sliding guide and a second engagement element configured to cooperate with a second sliding guide. The first engagement element and the second engagement element may be adjustable between a switching position and an inactive position. The adjusting device may further include a joint actuator configured to adjust at least one of the first engagement element and the second engagement element into the switching position.

Claim (Index 18):
A valve drive for an internal combustion engine, comprising:\n a cam shaft including at least one first cam and at least one second cam axially adjacent the at least one first cam, the at least one first cam and the at least one second cam arranged on the cam shaft in a rotationally fixed manner; a cam follower axially adjustable between a first position and a second position, the cam follower drivingly connected to the at least one first cam when in the first position and drivingly connected to the at least one second cam when in the second position; and an adjusting device including an adjustable first engagement element configured to adjust the cam follower from the first position to the second position and an adjustable second engagement element configured to adjust the cam follower from the second position to the first position, the first engagement element cooperating with a first sliding guide arranged on the cam shaft when in a switching position and not cooperating with the first sliding guide when in an inactive position, the second engagement element cooperating with a second sliding guide arranged on the cam shaft when in the switching position and not cooperating with the second sliding guide when in the inactive position, the adjusting device further including a joint actuator configured to adjust at least one of the first engagement element and the second engagement element into the switching position, the joint actuator cooperating with the first engagement element when in a first actuator position, cooperating with the second engagement element when in a second actuator position, and not cooperating with either of the first engagement element and the second engagement element when in an intermediate actuator position; wherein the joint actuator includes an actuator housing and an actuator element at least partially arranged within the actuator housing in an axially adjustable manner, the actuator element including a first axial element section protruding from the actuator housing such that the first element section is cooperatable with the first engagement element at least when the joint actuator is in the first actuator position, and a second axial element section protruding from the actuator housing such that the second element section is cooperatable with the second engagement element at least when the joint actuator is in the second actuator position.
