Abstract:
1. A cylinder head of an internal combustion engine with mechanical valve play adjustment, comprising: a valve drive for actuating a gas exchange valve, the valve drive having a lever-like cam follower arranged between a cam of a camshaft and the gas exchange valve, which cam follower is mounted on a support element, which is stationary in the cylinder head, with a rigid installation height and, for adjustment of the valve play with respect to the cam and/or the gas exchange valve, is dimensionally paired with the support element, wherein a module comprises the support element, which is mounted in a cylinder recess of the cylinder head of the cam follower that has a base opposing the cylinder head and a connecting element, which has a bottom wall with an opening and upwardly extending flanges that surround transverse outer walls of the base of the cam follower, captively retaining the cam follower on the support element by a snap-action, and which module has a defined total installation dimension, and whereby without readjustment after initial assembly of the valve drive into the cylinder head, the actual valve play within a nominal valve play is ensured.
