Abstract
A fuse plug pyrotechnic firing device includes a body, a pyrotechnic train, firing pin and a driving device. The body has an axis and a bore disposed along the axis. The pyrotechnic train is disposed along the axis and includes an upper part and a lower part. The firing pin has a firing pin axis and is disposed within the bore between the upper part and the lower part. The firing pin is also disposed to ignite the lower part. The driving device is coupled to the firing pin and to the upper part. The driving device drives the firing pin to move along the firing pin axis and to ignite the lower part, the firing pin rotating about the firing pin axis under pressure of gases generated by the ignition of the lower part. As a result, safe and effective operation of the fuse plug pyrotechnic firing device is ensured.
