Abstract
A governor for an internal combustion engine having an intake passageway and an engine throttle valve movable between an open position and a closed position, a throttle arm connected to the engine throttle valve to control movement of the engine throttle valve. A pressure assist adjusts the position of the throttle arm when a load is applied to the engine. The pressure assist includes a pressure responsive actuator having a pressure chamber in fluid flow communication with the intake passageway. The pressure responsive actuator is movable in a first direction in response to a pressure or a vacuum in the intake passageway. The throttle arm is movable in response to movement of the pressure responsive actuator. A conduit connects the pressure chamber and the intake passageway in fluid flow communication. A one-way valve is disposed in the conduit between the pressure chamber and the intake passageway.
