ABSTRACT:
An ignition device for igniting a rocket motor comprising a striker adapted or displacement by pressure generated by an auxiliary charge, a percussion-operated priming device for impact by the striker, and an ignition charge for ignition by the priming device and for igniting the rocket motor. The striker, in its inoperative position, is mechanically keyed within a hollow container body having an axial bore therethrough by a pair of diametrically opposed circumferential grooves within which an O-ring is retained. For operation, a fluid generates pressure on the striker, thereby dislodging it from its mechanical keying and driving it to impact the percussion-operated priming device.
