Abstract
An engine gas valve with a valve housing manifold with at least one flow passage and an annular clutch body arranged within the valve housing manifold. A drive shaft is arranged such that at least a portion of the drive shaft is positioned concentrically within the clutch body. A first valve element is supported on the drive shaft to rotate with the drive shaft within the at least one flow passage and a second valve element supported on the clutch body within the at least one flow passage. An actuator is coupled to the drive shaft to pivot the drive shaft between a first state in which the first and second valve elements are closed, a second state in which the first valve element is open and the second valve element is closed, and a third state in which the first and second valve elements are open.
