The ignition system of electrical more specially for firing ammunitions with socket a propellant charge fuel or without bush a propellant charge

摘要

There is disclosed an electric firing system adapted for weapons adapted for firing ammunition with a combustible casing or without a propellant charge casing, with an electrically conducting contact pin having an insulated body and an igniter point which is arranged in the bore of a breech block so as to be axially removable from the rest position to a firing position and back again into the rest position, and which is connectable with a voltage source when moved toward and into its firing position. In the disclosed system the contact pin in its rest position is in conducting contact with the mass of the breech block. A repeater lever is arranged with respect to the contact pin in such way that it moves the latter into the operating position against a restoring force, thereby electrically energizing the contact pin, and thereafter releases it to return to its rest position. In the rest position of the contact pin a cover member seals the end of the bore in which the contact pin is located from the bore of the barrel of the weapon.
