Governor for engine

Abstract

PURPOSE:To stabilize the function of a governor and simplify its construction, by applying the static pressure at the cooling fan of an engine to a diaphragm- type actuator to operate a throttle valve. CONSTITUTION:The static pressure chamber 6 of a diaphragm-type actuator 5 is connected to the static pressure port 3 of a cover 2 for the cooling fan 1 of an engine. The operating rod 11 of the actuator 5 is coupled to a throttle valve 13 at a carburetor 12. When the rotational frequency of the engine drops, the static pressure at the cooling fan 1 falls so that the actuator 5 opens the throttle valve 13 to keep the rotational frequency at a set level.
