System for variably actuating valves in internal combustion engines

A system for variably actuating valves in an internal combustion engine, comprising:

• a camshaft rotationally supported in a cylinder head of said engine, said camshaft having a fixed position in relation to the valves;
• a stroke-transmitting arrangement guided in a fixed position and associated with each of the valves arranged in the cylinder head, the valves closing by means of spring force, said camshaft having a fixed position in relation to said stroke-transmitting arrangement;
• a variable position element for adjusting the stroke of the valve and being guided in a stationary manner in the cylinder head;
• an intermediate element supported and pivotably guided on the variable position element;
• and
• a cam of the camshaft supported in a stationary manner in the cylinder head, said intermediate element engaging the cam and the stroke-transmitting arrangement;
• wherein the variable position element is adapted to pivot around an axis of swivel positioned fixed in the cylinder head and comprises a support cam and a control cam arranged one after the other, and wherein the intermediate element is supported in a force-locked manner on an outer contour of the support cam and control cam by a U-shaped inner contour opening.
