Valve drive for an internal combustion engine

A valve drive for an internal combustion engine, comprising:

• a camshaft including at least one cam group non-rotatably fixed on the camshaft, the at least one cam group including a first cam and a second cam disposed axially adjacent to the first cam;
• at least one cam follower being drive-connected to the first cam when in a first position and drive-connected to the second cam when in a second position;
• and
• at least one adjusting device including a first adjustable engagement element comprising a pin and a second adjustable engagement element comprising a pin, the first engagement element and the second engagement element arranged spaced apart from one another on the at least one cam follower, the first engagement element interacting with a first guide of a slotted guide arranged on the camshaft when in a first switching position and not contacting the first guide when in a first basic position, the second engagement element interacting with a second guide of the slotted guide arranged on the camshaft when in a second switching position and not contacting the second guide when in a second basic position, the at least one adjusting device further including a spring resetting arrangement and a stop arrangement axially shiftable relative to a rocker lever shaft, the stop arrangement including a first stop region corresponding to the first engagement element and a second stop region corresponding to the second engagement element, the first stop region and the second stop region protruding radially outwardly from the stop arrangement relative to the rocker lever shaft, the spring resetting arrangement configured to adjust the stop arrangement into a basic stop position;
• wherein at least one of i) the first engagement element is adjustable from the first basic position into the first switching position via the first stop region, and ii) the second engagement element is adjustable from the second basic position into the second switching position via the second stop region, when the stop arrangement is shifted along the rocker lever shaft;
• and
• wherein at least one of the first stop region and the second stop region include a ramp region.

• a stop arrangement axially shiftable relative to a rocker lever shaft, the stop arrangement including a stop rod having a first stop region corresponding to the first engagement element and a second stop region corresponding to the second engagement element;
• a bearing sleeve and a counter bearing sleeve nonshiftably arranged relative to the bearing sleeve, the stop arrangement shiftably mounted on the bearing sleeve and the counter bearing sleeve in a direction of the rocker lever shaft extending substantially along the rocker lever shaft;
• a linear actuator disposed on the bearing sleeve configured to shift the stop arrangement along the rocker lever shaft;
• and
• wherein at least one of i) the first engagement element is adjustable from the first basic position into the first switching position via the first stop region, and ii) the second engagement element is adjustable from the second basic position into the second switching position via the second stop region, when the stop arrangement is shifted along the rocker lever shaft.
