Description

og deretter unnslippe til et sekundært større forbrenningsrom. Også i det tilfelle at forbrenningsgassene ikke kan unnslippe sideveis til et større forbrenningsrom, men i stedet er tvunget til å strømme ut i løpets akseretning, har nevnte utførelse vist seg velegnet, nemlig når forbrenningsrommet foran er lukket av et skudd eller et prosjektil med en vekt fra 5° til ^ 00 ganger drivladningens vekt. Reduseres imidlertid prosjektilets vekt for å oppnå en nedsatt skudd-vidde eller gjennomslagskraft, f.eks. til øvelsesmanøvre til omkring 50 ganger drivladningens vekt, eller hvis det anordnes et større ekspansjonsrom mellom prosjektilet og avfyringspatronen for å unngå et for stort trykkmaksimum, da er de oppnådde resultater mindre til-fredsstillende. and then escape to a secondary larger combustion chamber. Also in the event that the combustion gases cannot escape laterally to a larger combustion chamber, but instead are forced to flow out in the axial direction of the barrel, the aforementioned design has proven suitable, namely when the combustion chamber at the front is closed by a shot or a projectile with a weight from 5° to ^ 00 times the weight of the propellant charge. However, if the projectile's weight is reduced to achieve a reduced range or impact, e.g. for practice maneuvers to around 50 times the weight of the propellant charge, or if a larger expansion space is arranged between the projectile and the firing cartridge to avoid an excessive pressure maximum, then the results obtained are less satisfactory.

Man fant nå at disse mangler kunne avhjelpes ved en avfyringspatron for skyts ifølge oppfinnelsen med et i drivladningen utformet sentralt akseparallelt kammer, som strekker seg fra drivladningens bakre ende over minst ca. 20 og maksimalt ca. 80$ av dens lengde, og patronen erkarakterisert vedat kammeret er utformet som en ved sin forreste ende lukket i og for seg kjent sylindrisk, fortrinnsvis av kunststoff fremstilt hylse som med sin åpne ende ved hjelp av klemsete er holdt på en i det vesentlige sylindrisk sentral-avsats av patronbunnen, idet denne med en ringformet flens griper inn i et ringspor av hylsen. For å sikre at kammeret er helt tomt, slik at antennelsesstrålen ikke hindres i sin utbredelse, er videre ifølge oppfinnelsen kammeret ved sin åpne ende mot tenningsladningen resp. forsterkerladningen lukket med en dekkskive av kunststoff. En særlig enkel og hensiktsmessig befestigelse for denne dekkskive oppnås ved at dekkskiven sammen med en utoverstikkende ringformet flens for patronbunnansatsen griper inn i et ringformet spor ved kammerets, dvs. hylsens åpne ende. It was now found that these deficiencies could be remedied by a firing cartridge for a projectile according to the invention with a central axis-parallel chamber formed in the propellant charge, which extends from the rear end of the propellant charge over at least approx. 20 and a maximum of approx. 80$ of its length, and the cartridge is characterized by the fact that the chamber is designed as a closed at its front end in a known cylindrical sleeve, preferably made of plastic, which with its open end is held by means of a clamping seat on an essentially cylindrical central -ledge of the cartridge base, as this engages with an annular flange in an annular groove of the sleeve. In order to ensure that the chamber is completely empty, so that the ignition beam is not impeded in its propagation, according to the invention, the chamber is further at its open end towards the ignition charge or the booster charge closed with a plastic cover disc. A particularly simple and appropriate attachment for this cover disc is achieved by the cover disc together with an outwardly projecting annular flange for the cartridge bottom attachment engaging in an annular groove at the open end of the chamber, i.e. the sleeve.

Oppfinnelsen er ved hjelp av utførelseseksempler vist på tegningen, og skal forklares nærmere under henvisning til disse. The invention is shown in the drawing with the help of exemplary embodiments, and shall be explained in more detail with reference to these.

Fig. 1 viser en avfyringspatron med innsatt øvelsesprosjek-til med ekspansjonsrom, og Fig. 1 shows a firing cartridge with an inserted practice projectile with expansion space, and

fig. 2 viser en avfyringspatron med ekspansjonsrom mellom patron og prosjektilbunn. fig. 2 shows a firing cartridge with an expansion space between the cartridge and projectile base.

På fig. 1 ligger patronen i våpenløpet 1 og har ved den fremre ende av hylsen 2 påsatt øvelsesprosjektllet 3 med den sentrale utsparing 4«Hylsen 2 er ved sin bakre ende lukket av patronbunnen 5, som i en sentral boring 6 opptar tennladning resp. forsterker- ladning 7 samt i boringens forlengelse bakover den ikke viste tenn-hette. Den sylindriske ansats 8 på patronbunnen 5 har en flens-aktig krave 9»som griper inn i et ringformet spor 13 i kammeret resp. hylsen 12 som i fremre ende er lukket og strekker seg i ca. 3/4 av lengden for drivladningen 10 i drivladningsrommet 11, hvorved hylsen 12 er klemt fast omkring ansatsen 8. Dekkskiven 14 som sitter på ansatsen 8 og likeledes griper inn i sporet 13, forhindrer at tennladningsmateriale faller inn i kammeret 13f og sørger således for at kammeret 12 er helt tomt. In fig. 1, the cartridge is in the weapon barrel 1 and has the practice projectile 3 attached to the front end of the sleeve 2 with the central recess 4"The sleeve 2 is closed at its rear end by the cartridge base 5, which in a central bore 6 receives the ignition charge resp. booster charge 7 as well as in the extension of the bore to the rear the ignition cap not shown. The cylindrical shoulder 8 on the cartridge base 5 has a flange-like collar 9" which engages in an annular groove 13 in the chamber or the sleeve 12 which is closed at the front end and extends for approx. 3/4 of the length of the propellant charge 10 in the propellant charge compartment 11, whereby the sleeve 12 is clamped around the shoulder 8. The cover disc 14, which sits on the shoulder 8 and likewise engages in the groove 13, prevents ignition charge material from falling into the chamber 13f and thus ensures that the chamber 12 is completely empty.

På fig. 2, hvor det er brukt de samme tall for samme deler som på fig. 1, er hylsen 2 lukket i sin fremre ende. Mellom denne frontende og bunnen av prosjektilet 3 befinner det seg et forholds-vis stort ekspansjonsrom 15. Kammeret 12 strekker seg i dette tilfelle bare noe over 2/3 av drivladningens 10 lengde. Bortsett fra en noe annen utformning av avfyringspatronens bakre ende, stemmer anordningen og utformningen av fig. 2 ellers overens med fig. 1. In fig. 2, where the same numbers are used for the same parts as in fig. 1, the sleeve 2 is closed at its front end. Between this front end and the bottom of the projectile 3, there is a relatively large expansion space 15. In this case, the chamber 12 only extends slightly over 2/3 of the length of the propellant charge 10. Apart from a somewhat different design of the rear end of the firing cartridge, the arrangement and design of fig. 2 otherwise consistent with fig. 1.
