Abstract
In an rpm limit shut-off regulation effected by a piston which is displaceable by the rpm-dependent pressure of a regulator fluid and which limits the injection quantity, it is proposed to influence the shut-off curve via a pressure roller which engages a contact surface of the piston. The shut-off curve can be selected to be steeper or flatter over the entire range or a partial range. However, without requiring additional means, the full-load injection quantity can also be influenced in accordance with the rpm. To this end, rapidly rotating parts with necessarily resulting high wear are not required.
