ABSTRACT:
Flyweights are connected to a fuel control rod through a tension lever and a floating lever. A speed control lever is connected to the floating lever so that the engine speed is determined by the rotational speed of the flyweights and the position of the speed control lever in combination. A governor spring is compressed between two spring seats which are slidably carried on a governor rod, and the tension lever moves against the force of the governor spring by engaging with one of the spring seats. A nut is threaded on the governor rod and retains the spring seat opposite to the tension arm. A pin integral with the nut is slidable in a groove in the governor housing so that the nut may move only axially. An end of the governor rod extends out through the housing so that rotation of the governor rod adjusts the compressive preload of the governor spring. The governor, which is basically an all-speed governor, may thus be made to function as a high-low speed governor. A fuel limiting lever is moved by the spring seat assembly to limit movement of the fuel control rod and thereby the maximum fuel injection volume. Latching means actuated by the tension lever latch the fuel limiting lever in a reduced fuel position after the flyweight speed increases above a predetermined value so that an overly rich fuel mixture may be provided for stirring. In one embodiment of the governor the fuel limiting lever is actuated by a cam which provides an optimum maximum fuel injection volume at all speeds.
