Abstract
An engine governor having overriding means for limiting the flow of fuel to an engine, means for moving the overriding means to an intermediate reference position upon actuation of the governor, and means for moving the overriding means from the reference position to other positions for limiting the flow of fuel to that suitable for operating the engine at speeds close to a set speed. Means for actuating the governor before the engine reaches the set speed, means for moving the overriding means from the reference position to the other limiting positions at a very slow rate, and means for moving the overriding means toward limiting the fuel flow to a minimum when an over-running load causes the engine speed to run a predetermined amount above the set speed. The engine governor may be combined with a load speed governor for independently governing the engine to a speed safe therefor, and to a lower speed safe for the load and may also have a power take-off governing mode which is selected automatically upon connection of the power take-off to the engine.
