VARIABLE MECHANICAL VALVE CONTROL FOR AN INTERNAL COMBUSTION ENGINE

摘要

Variable mechanical valve control has intermediate lever (7), which is connected to valve push rod (4) by means of shaft (8), in such a way that slide gate roller (6), which is rotatably mounted on shaft, is displaced by camshaft (1) in slide gate (9). First contact surface (10) on intermediate lever is supported in reinforced manner on eccentric shaft (11), or on second contact surface. Lever (16) is displaced using a working curve (13), said lever opening and closing the two-way gas valves (19). Elements are also provided, on a lifter (3) that is located on the push rod for the additional adjustment of the phase position of the valve elevations of the two-way gas valves with simultaneous play-free adjustment of the valve stroke and the invention is also equipped with elements for the additional independently controllable valve stroke opening and closing for each camshaft rotation.
