ABSTRACT:
A two speed governor for a fuel pumping apparatus which supplies fuel to an internal combustion engine comprises a source of fuel under pressure which varies in accordance with the speed of the engine. Fuel is supplied through a first orifice and a second orifice in series from the source. The second orifice is defined by a port the size of which is controlled by a manually operable rod while the first orifice is defined by a port the size of which is controlled by a spool responsive to the pressure of the source. The port closes at the maximum allowed engine speed. A third orifice defined by a port is also controlled by the spool and is connected in parallel with the second orifice. The port is closed at speeds above the idling speed of the engine. In the intermediate speed range the engine is controlled by the rod.
