The ignition charge 30 is accordingly in the "axis of the detonator. This ignition charge is intended for instantaneous ignition or immediate triggering when the projectile hits. The other ignition charge 31 of the drum carrier 11 takes in the Immediate release setting the position shown in Fig. 4

Rack abuts part of the body of the detonator, as in ^ 'ig. 13 is shown. When the rack has reached the end position, the ignition charge 41 of the same is in the axis of the detonator and from this point in time the various elements * of the pyrotechnic chain 30 or 31, 41 and a relay bl> of the detonator (Pig.8) are aligned with one another or are they in a line so that the ignition can take place. Before the rack reaches its end position, its rear end piece 48 passes in front of the lower end of the rod 27, which has the effect that this rod is no longer blocked in the position shown in FIG. T ^T nter the action of a not shown, and acting on the torsion spring 10 rotates Zündstiftriegel this bolt, whereby the ball 23 and the rod to be pushed down, since this rod is now restrained by nothing more. As soon as the firing pin lock has released the firing pin, the latter is able to trigger the ignition at the moment the projectile hits an obstacle. The action of the firing pin can take place in two ways: either by an impact or by hitting the central part 49 of the cap 3, which is crushed or depressed and thereby pushes or drives the firing pin downwards as shown in FIG. 1, or simply by inertia when the projectile hits an obstacle at high speed and in the latter case, in the

9Q9886 / Q783 " ¹³ "

The moment the projectile is braked or stopped, the drum carrier 11 becomes due to the force of inertia thrown forward, and the detonating charge or capsule 30 or 31 in an axial position strikes the tip of the firing pin. At 50, the spring is shown which normally holds the firing pin in the rest position.

The detonator shown is also equipped with flight path safety devices, which consist of a compensating lever actuated by a spring and the radial adjustment speed of a rack for the 'detonation charge'; this regulation takes place through the mediation of an inhibition. This trajectory safety devices comprise other first locking means (rod 17) to a partly the effect of the balance lever prior to launch, and the other part the displacement of the Zündstiftriegels to _prevent%. There are also additional locking means, which are represented by the rod 27 and the ball 23 and unct. serve to give the firing pin completely free only after a certain displacement of the rack. . - ..- · ■. - - · ~

The actuating spring 39 for the compensating lever is a ' Spiral spring, which in the inoperative position

My shape is an open V with single legs and which you can at least partially close when you tighten it. The calculation and experience show that such a spring has the advantage of less space requirement compared to the classic spring spring with the same force effect. When looking at FIGS. 9 to H, one will notice that the spring 39 is arranged between two organs (12 and 2) which, during the process of transferring it into the working position, in which the cover sleeve 2 is moved relative to the body 1, are movable in relation to each other and which - as already explained - are designed in such a way that this spring is tensioned on the occasion of this transfer into the operating position. . so the spring is not until time of the transfer in the Betriebs--, standing, shortly before the effective date of the igniter, tense Apart from this advantage, this arrangement brings yet another ^v orteil with it: Since the spring is not under tension is located, can also - if the safety devices should fail accidentally due to the breakage of a part - the rack rack cannot accidentally move "* * '~ straightened the position of the protechnical chain before the transfer to the closed position, which prevents serious accidents. Through the inequality '

of the two legs of the spring 39, the advantage evident when comparing FIGS. 9 and 13 is obtained. The stroke required to tension the spring, i.e. the stroke required to move it into the in * 'ig. To transfer position shown 11, is significantly less than the apparent from FIG. 13 stroke. In addition, it can be seen from this / figure that the spring is not completely relaxed, since it must be ensured that the rack reaches its end position under the action of a spring that is still sufficiently tensioned.

The described embodiment contains so-called anti-sabotage devices, n ^ ter sabotage means willful or deliberate damage or danger to the detonator, be it when handling the sunder, be it during its transport or when firing a shot, without: : au,; en something becomes visible on the detonator.

Antisabotage devices seen consist of a right outer end of the rack 12 in I'ig. 1 attached pin 58. A compression spring 59 arranged in a hole in this rack acts uninterruptedly on pin 58, since it protrudes from the rack to the inside, as shown in E ¹ Ig. 1. Is shown. In the part of the body 1 a bore 60 is provided which is located opposite the pin 58, if all the organs of the detonator are in the locking position. This drilling ;; 60 has a diameter that is just sufficient for the pin 58 to pass through it.

The cover sleeve 2 of the detonator moves over the The place where the drill 60 is located, continue to mix, and it points towards this hole (always as soon as the organs are in the safety position are located) a radial bore 61, which a Sewinae 5 * 1, into which a pin 52 is screwed is * If someone acts through sabotage « should succeed in shifting the rack 12 to the right (M> .f) without the Capsule: 2 with Besu.g on the body 1 is turned »like this it will emerge from this that 'the pin 58, of whose "existence the saboteur knows nothing about" passes through aie bore 60 and partially in

909 8 867 07 83 bad

the bore 61 engages. From this point on, the cover sleeve 2 is completely blocked with respect to the body 1 and it is therefore no longer possible for the operator to act on the cover sleeve in order to bring the organs into the preparation position for firing. His attention is therefore drawn to the fact that something is wrong ^a and the detonator is put aside.

These anti-sabotage devices do not in any way interfere with the normal operation of the detonator. In fact, as soon as the cover sleeve is rotated with respect to the body 1 in order to bring the organs into either the immediate release or the delay position, the locking rod 12 is at the left end of its path, that is to say that the pin 58 is outside the bore 60 and 61 to lie korm.it. The capsule can therefore rotate without the pin resisting. As soon as the spring 39 moves the rack 12 to the outer right-hand side of its path, the pin 58 passes through the bore 60 and encounters a full section of the cover sleeve 2 (FIGS. 13 and 14). Since the spring 59 is much weaker than the spring 39, it gives way, and the pin 58 pushes it back as the rack approaches its end position.

In Fig. 15 a variant is shown in which the spring pin 58 is replaced by a pin 62 in the egg Rack 12 is screwed in. The bore όΟ of the "body 1, the bore 61 of the cover 2 and the Stopper 52, which closes this opening 61 from the outside, "" "" ' are also present in this embodiment. A radial bore 63 is provided in the cover sleeve 2 opposite the point that the pin 62 occupies when the organs are in the. Delay position. There is also a radial bore 64 in the cover sleeve 2 provided at the point that the pin 62 occupies in the so-called immediate release position. Jiese's holes, which are closed to the outside by plugs 65, 66, are used to accommodate the outer change of the pin 62 to give the rack 12 the possibility " -to give to move to the end of their path, without being hindered by the pin.

* To block organs in the working position and thus to prevent any accidental relative movement of these organs during the service.

In the embodiment according to FIG. 16, they are correct most of the organs are identical to the example of the first embodiment and therefore will not be renewed described. So you limit yourself to that

In this second embodiment, the cover sleeve 2 does not drop down as much as in the first example, and it also does not reach the level of the plane in which the rack 12 is displaced. A handle carried by this toothed rack, such as the pin 58, can therefore not interact directly with the cover sleeve 2 . Instead of this pin 53, a conical head o7 is provided in its place, aem aem a radial Bohrimg o8 in the body 1 is provided opposite. This bore is closed on the outside by a three-way hole 69.
