ABSTRACT:
The invention is directed to a shut-off valve for stopping the air-flow to an engine. A butterfly valve disposed in an air passage is moved between a first open position and second closed position in a controlled fashion to prevent the build up un-burnt fuel in the event of the activation of the valve.
