Abstract

The invention relates to a valve controller (1) for an internal combustion engine. The valve controller (1) has a camshaft (4), and two cam groups (5, 6) are arranged on the camshaft at an axial distance from each other. The valve controller (1) has a roller bolt (9) comprising two rotatable rollers (9a, 9b) axially spaced apart from each other. The valve controller (1) is provided with an adjusting assembly (11), and the adjusting assembly comprises a switching pin (13). The switching pin (13) is arranged between two rollers (9a, 9b) and is arranged in the roller bolt (9) in an axially movable manner, and the guide (7) with the slot is fixed to the camshaft (4) between the two cam groups (5, 6) in a rotationally fixed manner. The rollers (9a, 9b) are arranged on the roller bolt (9) in anaxially movable manner and are axially coupled to the switching pin (13).

Description

technical field [0001] According to the preamble of claim 1, the invention relates to a valve controller for an internal combustion engine. Background technique [0002] Valve controllers are used to variably control valves of an internal combustion engine. The valve controller can thus be realized, for example, as a sliding roller system. The rollers are thus mounted on movable roller bolts which can be adjusted axially in two positions. In the respective positions, the rollers co-operate alternately with mutually different cam profiles, which influence the lifting movement of the rollers as well as that of the tilting lever via the latter. By adjusting the rollers, the valve can thus be variably controlled. To adjust the roller bolts including the rollers, sometimes a switching pin is used, which can be operated by an actuator and which cooperates with a guide with a slot. Guide grooves that axially guide the switching pins and the roller bolts connected thereto into c...
