The invention relates to a sliding-cam valve gear for an internal combustion engine, comprising a camshaft, which comprises a carrier shaft (1) and a cam piece (2) displaceably arranged thereon, which cam piece comprises at least one cam group (3, 4) having different cam elevations and an axial groove having a first groove track (7) and a second groove track (8), the axial elevations (S1, S2) of which in the cam rotational direction are directed opposite each other, are arranged completely one behind the other, and are spaced from each other by a retraction region of the second groove track, and comprising an actuator pin (9) that can be retracted into the axial groove for moving the cam piece in the direction of the two groove tracks. The circumference of the cam piece through which the axial groove passes is designed to have different diameters (D1, D2) on the two sides of the axial groove, wherein the smaller diameter (D2) transitions into the retraction region of the second groove track. |
