Valve drive for IC engines has thrust crank-like pressure lever supported on valve shaft and on intermittently rotating support body

摘要

The valve drive has a thrust crank-like pressure lever (5) is pref. supported indirectly on the valve shaft (8), on its side away from the eccentric drive (1,20), on the support body (6) in the cylinder head. The support body is pivoted but does not move constantly. It has a support contour, which has radial different dimensions measured from the pivot axis, for different opening angles, angle positions, and opening stroke.
