Abstract
An air intake shutoff device is disclosed for an engine. The device includes at least two air shutoff valve assemblies. Each of these assemblies has a gate for controlling air flow into the engine. A linkage couples together the gates of each of the air shutoff valve assemblies such that closing of one gate of the at least two air shutoff valve assemblies effectuates closing of all other gates of the at least two air shutoff valve assemblies.
