Definitions

the invention relates to an ignition device according to the preamble of claim 1.
EP 0243987 discloses such an ignition device.
the force element cooperating with the rotor has a force element bolt, which is pulled out of the rotor for releasing the rotor for arming the ignition device. This means that in case of accidental ignition of the ignition device, the locking of the rotor canceled and thus a safe rotor lock is not guaranteed.
the invention is therefore an object of the invention to provide an ignition device of the type mentioned, in which at an unintentional ignition of the ignition device, the rotor remains reliably locked in the securing.
the rotor in the circumferential direction spaced from one another for securing associated first bore and a sharpening associated second bore, wherein the first bore is shorter than the second bore, and in that the force element comprises a force element bolt, the in the assurance of the rotor at an unintentional premature ignition of the ignition device is shot into the first bore and remains connected to the power element and locked the rotor, and which is fired to focus the rotor in the second bore and separated from the force element, after which the rotor the elastic drive element is rotated into the armed position, resulting in an inadvertent ignition advantageously a simple and safe rotor locking by the shot into the first bore of the rotor and connected to the force element remains en power element bolt.
first and the second bore are radially oriented in the rotor and the force element is radially oriented to the rotor.
the rotor is preferably formed with a circumferentially oriented elongated recess at one end of the first bore and at the opposite second end of the second bore is provided.
the force element bolt of the force element is in the securing position in the elongated recess of the rotor.
the pulse protection of the ignition device i. the first rotor lock, canceled, so the rotor rotates due to spin around an angle defined by the elongated recess in the rotor, the rotor however remains in the elongated recess in the securing by the engagement of the force element bolt.
the force element bolt In the armed position of the rotor, the force element bolt is shot into the second hole and is fixed in it - and separated from the force element - as has already been stated above.
the rotor can then rotate with the help of the elastic drive element provided on it in the armed position, so that the ignition chain of the swirl ammunition is "in line".
an ignition transformer is provided on the diametrically opposite side of the first and the second bore.
FIGS 1 to 4 illustrate an ignition device 10 for a swirl ammunition.
the ignition device 10 has a base 12, on which a rotor 14 is rotatably mounted. Between the base 12 and the rotor 14, an elastic drive element 16 is provided.
the elastic drive element 16 is formed by a mechanically tensioned coil spring.
the base part 12 has a force element 18 with a force element bolt 20.
the rotor 14 of the ignition device 10 is formed on its lateral surface 22 with an elongate recess 24 which is oriented in the circumferential direction of the rotor 14. At one end of the elongate recess 24 is a first bore 26 and at the opposite other end of the elongated recess 24, a second bore 28 is provided, which are radially oriented in the rotor 14. Accordingly, the force element 18 is radially oriented to the rotor 14.
a cover (not shown) can be arranged or arranged on the base part 12 in order to realize a self-contained ignition device 10.
pins 30 and holes 32 are formed.
an ignition transformer 34 is provided which is not “in line” in the illustrated in Fig. 1 assurance of the ignition device 10 with the ignition chain of the swirl ammunition.
the first bore 26 has a length that is smaller than the length of the second bore 28.
the ignition transformer 34 is provided in the rotor 14 of the ignition device 10 on the first and the second bore 26 and 28 diametrically opposite side.
the ignition transformer 34 provided in the rotor 14 is swung out of the ignition chain and secured.
This assurance of the rotor 14 is achieved by a (not shown) momentum protection of the rotor 14, which may be a per se known double bolt system, and characterized in that the force element bolt 20 of the force element 18 into the elongated recess 24 of the rotor 14 stands ,
the rotor 14 is locked in the Fig. 1 corresponding assurance. This locking is effected by the force element bolt 20 is shot into the first bore 26 of the rotor 14 and remains connected to the force element 18, because the first bore 26 is suitably short dimensioned. The rotor 14 remains locked in such a premature unintentional ignition so in the security; a further release is not possible.
the aforementioned first rotor protection i.e. the pulse fuse
the ignition device 10 remains in the securing position by engagement of the power element bolt 20 in the elongated recess 24 in the rotor 14, i. the ignition transformer 34 remains swung out of the ignition chain.
the arming of the rotor 14 of the ignition device 10 to its focus is done by shooting the power element pin 20 into the second bore 28, as Fig. 3 illustrates.
the second bore 28 has a length such that the force element pin 20 is separated from the force element 18 and fixed in the second bore 28.
the connection between the rotor 14 and the base part 12 of the ignition device 10 is released, so that the rotor 14 can rotate by means of the elastic drive element 16 in the armed position in which the ignition transformer 34 with the ignition chain is "in line".
