Valve train of internal combustion engine, has orientation unit that is cooperated with guide element and is elastically expanded under action of guide element from stroke curve to define axially extended position

摘要

The valve train (1) has a cam shaft (2) that includes a cam (5) to actuate gas shuttle valves (9). A cam element (3) includes cam tracks (6,7) displaceably and axially guided on the cam shaft. A stroke profile (12) with stroke curves (13,14) is assigned to the cam element. A guide element is provided in the cam for axial shifting of the cam element and retractably arranged into stroke curve. An orientation unit is cooperated with the guide element and is elastically expanded under action of the guide element from the stroke curve to define axially extended position.
