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.
Claims4
In a governor for an engine having a throttle movable between an open throttle position and a close throttle position for regulating the flow of fuel to the engine, said governor being of the type comprising an overriding throttle closing means, a control means including engine speed sensing means, and actuating means for moving said throttle closing means to a position for limiting the engine speed to a predetermined governed value, said governor being of the type which requires electrical power supply for operation and including an electrical conductor for supplying electrical power to the governor from a power source, the improvement comprising:
- holding means for arresting said overriding throttle closing means against movement in the open throttle direction,
- and control means for operating said holding means to arrest said overriding throttle control means in response to interruption of the supply voltage to said governor,
- whereby movement of the throttle in the open throttle direction is prevented.
