  • Patent number: 5227577
    Abstract: A device for firing ammunition includes a combustion chamber accommodating several propellant charge members which latter contain a propellant charge and an ignition system for igniting the propellant charge. A fixedly disposed primary coil which receives an ignition signal is provided at the combustion chamber while a secondary coil is arranged in each propellant charge member, this secondary coil being connected to a resistor initiating the ignition system. The magnetic field, changing with time, which is produced by the primary coil penetrates the combustion chamber and induces a current in the secondary coils of each propellant charge member at the same time so that the ignition systems of all propellant charge members are simultaneously activated and ignite all propellant charges at once. On account of the simultaneous ignition of the propellant charge members, rapid firing sequences can be attained.
