ABSTRACT:
An improved rpm regulator for a fuel injection pump associated with an internal combustion engine. The regulator includes a suction chamber, an intermediate lever, a fuel quantity control sleeve connected to the intermediate lever, a regulating spring assembly connected to the intermediate lever, a device including centrifugal weights and a governor sleeve for developing and transmitting an rpm signal through the intermediate lever to the fuel quantity control sleeve in opposition to a force exerted by the regulating spring assembly, a control lever, and an adjustable stop, including a cam member, mounted to the housing for limiting the motion of the intermediate lever. A working chamber is provided between the governor sleeve and an end of a guide shaft forming part of the device for transmitting an rpm signal. Openings are provided in the governor sleeve which communicate with the suction chamber for effecting a damping of oscillations of the governor sleeve during predetermined load conditions.
