ABSTRACT:
A fuel flow control lever is pivotably mounted for movement between fuel-off and fuel-on positions wherein it respectively engages first and second stops. A solenoid has its plunger linked to the control lever and when the solenoid is deenergized, a spring acting on the plunger holds the latter in an extended position wherein it holds the lever in its fuel-off position. A pair of coils surround the plunger and are selectively simultaneously energizable to retract the plunger to effect movement of the lever to its fuel-on position. The linkage between the plunger and lever is yieldable and the lever reaches its fuel-on position prior to the plunger becoming fully retracted. Upon the plunger becoming fully retracted, a normally closed switch is opened to de-energize one of the coils.
