<p>An emergency throttle limiter (20) is disclosed for a top speed limiting governor (10) 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 (42) is provided for arresting the throttle closing device against movement in the open throttle direction and an electromagnet (93) maintains the brake (42) in a released condition as long as electrical power is supplied to the governor (10). When the power supply is interrupted, the electromagnet (93) is deenergized and allows the brake (42) to be engaged to arrest the overriding throttle control device against movement in the open throttle direction.</p> |
