ABSTRACT:
An engine air shutdown valve comprising a gate which is movable from a first position wherein the air flow passage of an engine is relatively unimpeded to a second position where the air flow passage is closed thereby terminating operation of the engine. A trip spindle maintains the gate in its open position with a ball release. Upon activation of the ball release, the gate moves parallel to the direction of air flow through the passage to terminate the air flow.
