Abstract

A sliding cam valve train for an internal combustion engine is provided. A cam piece (3) displaceably arranged on a carrier shaft (2) includes a cam group (4, 5) with differing cam lifts and an axial groove with two groove tracks (8, 9), which are arranged completely behind one another in the circumferential direction of the axial groove. An actuator pin (10) which may be introduced into the axial groove displaces the cam piece in the direction of both groove tracks. Each of the groove tracks end with a radially lifting ramp (17, 18) for extending the actuator pin from the axial groove. The radial lift of the exit ramps should be significantly smaller than the groove base depth of the axial groove between the exit ramps.
