ABSTRACT:
A valve operating mechanism for an internal combustion engine for an automobile in which friction is decreased without an increase in the mass to be moved by the valve closing spring. The valve operating mechanism has a roller arranged on an actuation spindle. The roller cooperates with a bearing surface on a component of the mechanism that is connected to the valve, at least during valve opening, so that deviations of the valve lift curve from the desired valve lift curve are eliminated. Connection between the actuation spindle, through the roller, and the valve is maintained only during the valve-open cycle.
