Abstract
Pyrotechnic/explosive initiator for use with a detonating cord or fuse comprising an elongated hollow tube with a longitudinally extending channel through which a gaseous percussion wave is propagated. The initiator includes a charge of pyrotechnic or explosive material and a valve for cutting off communication between the gas channel and the charge upon initiation of the charge to prevent gases and other reaction products from being exhausted back into the fuse.
