Abstract
An improved rpm regulator for a fuel injection pump associated with an internal combustion engine. The regulator includes a control lever, a fuel quantity control sleeve connected to the control lever, a regulating spring assembly connected to the control lever, a device for generating an rpm signal and applying a corresponding force through the control lever to the fuel quantity control sleeve in opposition to a force exerted by the regulating spring assembly and an adjustment lever connected to the regulating spring assembly for adjusting the preload exerted by the regulating spring assembly. The regulating spring assembly is improved and includes two holding members containing two compression springs so that when the two holding members are moved outwardly relative to each other the two springs are compressed. The springs are chosen and the holding members designed so as to minimize the degree of variation which can occur during a control process.
