摘要： A valve train device, in particular for an internal combustion engine, includes at least one camshaft which has at least one cam element with at least one multi-track cam. The cam element is provided to be axially displaced by a maximum displacement path. The valve train device further includes a limiting mechanism which is provided to limit in at least one operating state the displacement path of the cam element to a switching path of the switching operation.

摘要： In a motor vehicle camshaft adjusting device which comprises an open- and/or closed-loop control unit for adjusting the camshaft phase position in a normal operating mode to a temporarily intermittently constant phase position, the open- and/or closed loop control unit has an engine start operating mode in which the camshaft phase position is advanced during opening of the valve so as to provide a valve opening angle range which is smaller than a geometric normal opening angle range based on a crankshaft angle range.

摘要： A valve drive device has a camshaft which includes a shaft element and a cam piece which can be driven by the shaft element and a first cam effecting a first stroke of a valve and a second cam effecting a second stroke of the valve, and is displaceable in the axial direction of the camshaft relative to the shaft element between a first position, in which the valve can be actuated by the first cam, and a second position in which the valve can be actuated by the second cam, and has an electrically controllable actuator via which the cam piece is displaceable relative to the shaft element in the axial direction as a result of an electrical control of the actuator. The actuator pushes the cam piece alternately back and forth between the positions in the case of successive electrical controls occurring with the same polarity.

摘要： A valve train device, particularly for an internal combustion engine, includes a camshaft, a cam element able to be displaced axially on the camshaft, and a mechanical displacement element which is provided on the camshaft for the purpose of axially displacing the cam element. The mechanical displacement element is provided to move the cam element by interaction with only a single contour of the cam element in a first and a second axial direction.

摘要： A valve train device, in particular for an internal combustion engine, includes a support element and a cam element which can be moved axially relative to the support element. The valve train device further includes a switch unit for axially moving the cam element, which switch unit includes a displacer that is intended to be at least operatively inserted between the support element and the cam element in order to axially move the cam element.
