Definitions
- Ignition device in particular for a propellant charge of an anti-tank anti-tank training weapon
- the invention relates to an ignition device according to the preamble of patent claim 1.
- Such igniters are used to ignite a charge encapsulated in a container and
- Anti-tank weapon used. Such practice weapons have a launch tube into which the patronized
- the propellant cartridge is charged in a container, e.g. B. made of aluminum, and is ignited by a lighter, this in a housing a primer, an ignition charge and a
- Propellant charge The hot gases of the ignition charge can then penetrate into the container of the propellant charge and ignite it.
- the lighter which must be replaced after each shot, must be held firmly and in a pressure-tight manner with respect to the launch tube in the receiving device during the ignition process; in addition, the primer charge has to be sealed on the outside so that no air or moisture can enter. This is the only way to ensure reliable ignition of the ignition charge even after a long storage period.
- an igniter is known in which the igniter is screwed into the receiving device on the circumference of its housing with the aid of an external thread.
- the housing of this igniter is divided into two parts, an inner housing being screwed into an outer housing carrying the thread, in which the primer cap, the charge and the bullet element are received.
- the bullet element is a cylinder with a lower ring flange lying on the charge. There is one between the ring flange and the cylinder
- a ring seal is located beyond the charge, which is pressed against the ring flange by flanging the inner housing and thus seals the charge.
- Exercise anti-tank weapon first twisted two rotating rings before the lighter out of the
- Unscrewed cradle and a new lighter can be used.
- the igniter housing has a grip edge on the underside, which makes it easier to screw in and out, it has a diameter of just over 1 cm. It is obvious that both unscrewing a used lighter and screwing in a new one require a lot of time and patience as well as skill.
- the invention has for its object to construct an igniter of the type in question, so that an economical
- the igniter consists of a simple to produce single rotating part for the housing of the igniter with a conical outer wall and a central bore and a likewise conical receiving device.
- the lighter is no longer screwed into the receptacle, but is simply pushed in, the conical design of the outer walls of the lighter and the inner walls of the receptacle ensuring a gas-tight fit of the lighter.
- Bullet element only a preferably stepped bore must be made in the igniter housing.
- the penetration element is preferably a ball which is pressed into the narrowest bore part of the stepped bore at the top of the igniter housing and thereby seals the ignition charge to the outside. The seal can be improved if the space between the ball and the bore is through
- Sealant e.g. B. a sealing lacquer is filled.
- the igniter housing can be automatically produced from a single blank on a machine tool.
- the primer cap, the primer charge and the ball are then inserted into the finished igniter housing.
- the handling when inserting and replacing the lighter can be significantly simplified in that the receiving device by a pivotable cover is closable, which in the closed state rests with an inner surface on the underside of the igniter housing.
- a compartment is provided in the lid below the mentioned inner surface, in which a spring-supported firing pin for the primer cap and a securing element for the firing pin extend through the inner surface.
- the lid is preferably kept closed with a ball catch.
- Figure 1 is a partially sectioned longitudinal section through a ciprora with an igniter according to the invention.
- FIG. 2 shows a longitudinal section through an ignition device according to the invention
- Fig. 3 shows a longitudinal section through an igniter for a
- a training weapon 1 is shown in the form of a bazooka with a launch tube 2 and a mock projectile 3 inserted into it.
- a firing device 4 and a telescopic sight 5 are connected to the launch tube, and an exercise cartridge 6 is inserted into an inner tube of the dummy floor 3, which cartridge is next to a sub-caliber
- Training floor has a propellant or Deut charge 7 for driving out the training floor and a counterweight.
- the propellant charge 7 is a
- Igniter 8 ignited, which is shown in more detail in Fig. 2.
- the propellant charge 7 is cylindrical
- the igniter consists of a gripping through the wall of the launch tube 2
- Receiving device 21 an igniter 22 inserted therein and a cover 23 covering the receiving device 21.
- the igniter 22 has a truncated cone-shaped housing 31 with a conical side wall 32, a grip ring 33 on the broad base of the truncated cone and a cylindrical extension 34 on the narrow base of the truncated cone.
- the receiving device 21 has a corresponding conical inner wall 35 corresponding to the conical outer wall 32 of the igniter and a cylindrical inner bore 36, which opens into the launch tube 2 in the area of the predetermined breaking point 10 of the propellant charge 7, a circumferential groove 37 is also provided in the cylindrical insert 34 of the igniter 22, into which an O-ring 38 is inserted, which connects the igniter 22 against the cylindrical bore 36 the receiving device 21 seals. If the lighter 22 in the
- a central, stepped bore 41 is provided in the igniter housing 31.
- a first partial bore 42 with the largest diameter of the stepped bore on the broad base of the truncated cone housing is a
- This bore 42 is followed by a further sub-bore 44 with a smaller diameter, which receives an ignition charge 45.
- This partial bore 45 extends in the axial direction up to approximately the area in which the conical outer wall 32 of the igniter merges into the cylindrical extension 34.
- the space between the ball 47 and the partial bore 46 is filled with a sealing lacquer 48.
- primer 43 e.g. B. by a
- Firing pin is initiated, ignites the ignition charge 45, whereby the ball 47 from the partial bore 46 is expelled and penetrates the container 9 of the propellant charge 7 in the area of the predetermined breaking point 10.
- the hot gases of the burning igniter charge 45 then flow through the opened hole in the container and ignite the propellant charge.
- the sub-caliber projectile cartridge 6 is driven out of the launch tube 2 in a known manner by expelling the countermass with the aid of the propellant charge, the dummy projectile 3 remaining in the launch tube 2.
- the gas-tight connection between the inside of the firing tube 2 and the igniter can be further improved by a configuration of the conical outer wall 32 of the igniter 22 which is stepped in cross-section, as shown in dashed lines by 51 in the left half of FIG. 3.
- These circumferential sealing ribs act like a labyrinth seal, so that an absolutely gas-tight fit of the igniter 22 in the receiving device 21 is ensured.
- This cover can be pivoted about a shaft 61 connected to the launch tube 2 in the direction of arrow P and is locked in the closed state, as shown in FIG. 2, by a ball catch 62.
- an inner surface 63 rests on the underside of the igniter 22.
- This inner surface 63 has a central opening 64, through which a firing pin 65 extends, which is supported by springs 66.
- the firing pin 65 and the springs 66 are together with a locking pin 67 in a extending down to the inner surface 63 Compartment 68 of the cover 23 is arranged. If the locking pin 67 supported by a spring 69 is shifted by a certain amount, the spring-loaded firing pin is released and strikes it
- the igniter described can also be used with live ammunition.
