  • Valve bridge for a valve train of an internal combustion engine, especially of a motor vehicle, and internal combustion engine
    Patent number: 12698731
    Abstract: The invention pertains to a valve bridge (42) for a valve train (10) of an internal combustion engine, having a bridge actuation area (44), via which the valve bridge (42) can be actuated by means of a first rocker lever (32) of the valve train (10) and can thus be moved in translational motion in a first direction of movement (22), having a first valve actuation area (46), via which, by actuating the valve bridge (42), a first gas exchange valve (18) of the internal combustion engine can be actuated by means of the valve bridge (42), and with a second valve actuation area (48), via which, by actuating the valve bridge (42), a second gas exchange valve (20) of the internal combustion engine can be actuated by means of the valve bridge.

  • Valve train for an internal combustion engine, in particular of a motor vehicle, and internal combustion engine
    Patent number: 12276213
    Abstract: The invention relates to a valve train (10) for an internal combustion engine, having a first rocker arm (32) which is mounted on a rocker shaft (30) so as to be pivotable around a pivot axis (44) in relation to the rocker shaft (30), having a first gas exchange valve (18) which can be actuated by pivoting the rocker arm (32) around the pivot axis (44) in relation to the rocker shaft (30) and can thus be moved translationally, and having a second gas exchange valve (20).
