Abstract
A speed governor for fuel injection pumps of internal combustion engines that has a centrifugal adjuster that acts counter to the force of governor springs to generate a speed-dependent adjustment travel of a governor sleeve and that acts on a fuel quantity adjusting device of a fuel injection pump via the governor sleeve and a governor lever disposed thereupon In this process a charge-pressure-dependently adjustable stop for a full-load fuel supply quantity, which is disposed on a stop lever is pivoted as a function of temperature and speed into the adjustment path of a counter stop disposed on the fuel quantity adjusting device, in such a way that, after a certain speed and a certain operating temperature of the engine has been reached, the stop comes into contact with this counter stop of the fuel quantity adjusting device. For this purpose the stop lever has two lever arms, and a temperature-dependently controlled governor member which acts on the first lever arm, and a speed-dependently-controlled control lever which acts in the same direction of rotation on the second lever arm.
