ABSTRACT:
An emergency throttle limiter is disclosed for a top speed limiting governor of a vehicle. The governor is of the type which comprises an overriding throttle closing device for moving the throttle to a position for limiting the engine speed to a governed value. A brake is provided for arresting the throttle closing device against movement in the open throttle direction and an electromagnet maintains the brake in a released condition as long as electrical power is supplied to the governor. When the power supply is interrupted, the electromagnet is deenergized and allows the brake to be engaged to arrest the overriding throttle control device against movement in the open throttle direction.
