Description

Anordning ved drivladningshylse. Device at propellant sleeve.

Det er kjent å anvende foran lukkede hylser, særlig for plastpatroner, hvilke hylser er laget av et elastisk kunststoff og på sin mot tenningssiden åpne ende har på-skjøvet en form- og tettsluttende rørfor-met forlengelse av et metallisk bunnstykke, hvorved lengden av den indre hylse omtrent tilsvarer lengden av patronlageret i våpe-net og i hvilken hylses hulrom det er anbragt krutt som tennes av en tennsats. Hylsens fremre, lukkede ende er forsynt med kryssede svekklinjer der hvor hylse-veggen skal briste ved gasstrykket. It is known to use front-closed sleeves, especially for plastic cartridges, which sleeves are made of an elastic synthetic material and on its open end towards the ignition side have a shaped and tight-fitting tube-shaped extension of a metallic bottom piece pushed on, whereby the length of the inner sleeve approximately corresponds to the length of the cartridge magazine in the weapon and in which sleeve cavity is placed gunpowder that is ignited by an igniter. The front, closed end of the sleeve is provided with crossed lines of weakness where the sleeve wall should burst under the gas pressure.

Den spesielle hensikt med oppfinnelsen er å tilveiebringe en drivladningshylse som kan lagres uten innsatt prosjektil. Ladnin-gene skal være avskj ermet mot ytre påvirkninger, slik at selv ved lengre lagringer vil ikke skadelige medier, såsom fuktighet, luft og lignende kunne trenge inn. The particular purpose of the invention is to provide a propelling charge sleeve which can be stored without an inserted projectile. The loads must be shielded against external influences, so that even during longer storage, harmful media such as moisture, air and the like will not be able to penetrate.

I henhold til oppfinnelsen er det så-ledes tilveiebragt en anordning ved drivladningshylse som består av et metallbunnstykke, en til dette festet, oventil lukket kunststoffhylse for opptak av en drivladning og en annen likeledes til bunnstykket festet, oventil lukket kunststoffhylse for opptagelse av en tenningsforsterkerladning,og ifølge oppfinnelsen er anordnin-gen kjennetegnet ved at drivladningshylsen som en i og for seg lukket del kan innsettes i en boring i et legeme som skal avfyres og kan fastklemmes i dette legeme. According to the invention, a device for a propellant charge sleeve is thus provided which consists of a metal bottom piece, a plastic sleeve attached to this, closed at the top for receiving a propellant charge and another similarly attached to the bottom piece, closed at the top, a plastic sleeve for receiving an ignition booster charge, and according to the invention, the device is characterized by the fact that the propellant sleeve as an inherently closed part can be inserted into a bore in a body to be fired and can be clamped in this body.

En slik drivladningshylse kan lagres også uten prosjektil med tennings- og kruttdrivstoffet, fordi disse stoffer også uten anbragt prosjektil er beskyttet mot ytre påvirkninger. Ved en ved et uhell for-årsaket tenning kan det ikke oppstå større skade fordi det ikke kan oppstå et farlig eksplosjonstrykk på grunn av en hurtig oppriving av kunststoff hy Isene. Such a propellant case can also be stored without a projectile with the ignition and gunpowder fuel, because these substances are protected against external influences even without a projectile attached. In the event of an accidental ignition, no major damage can occur because a dangerous explosion pressure cannot occur due to a rapid tearing of plastic hy Isene.

Ved tenning av drivladningen vil kunststoffhylsene rives av nær metallbunnstykket, slik at etter avfyringen vil bare tenningsbæreren med den avfyrte tennsats forbli i partonlageret, mens prosjektilet eller det avfyrte legeme vil skytes ut sammen med praktisk talt hele kunststoffhylsen. When the propellant charge is ignited, the plastic casings will be torn off close to the metal bottom piece, so that after firing only the ignition carrier with the fired fuse will remain in the parton store, while the projectile or the fired body will be ejected together with practically the entire plastic casing.

Ved en fordelaktig utførelsesform kan den ytre kunststoffhylse være forsynt med en ringvulst, og legemet som skal avfyres vil da være forsynt med et motsvarende ringspor, i hvilket ringvulsten' snepper inn ved elastisk deformering av kunststoffhylsens nedre del, slik at man derved til-veiebringer en forankring mellom drivladningshylsen og legemet som skal avfyres. Med den utførelse oppnås det at kunststoff - hylsen avrives umiddelbart foran ytter-vulsten. In an advantageous embodiment, the outer plastic sleeve can be provided with a ring bead, and the body to be fired will then be provided with a corresponding ring groove, into which the ring bead snaps by elastic deformation of the lower part of the plastic sleeve, so that one thereby provides a anchorage between the propellant case and the body to be fired. With this design, it is achieved that the plastic sleeve is torn off immediately in front of the outer bead.

Drivladningshylsen kan naturligvis anvendes for mange formål, og den kan f. eks. fordelaktig anvendes som avfyringshylse for en kastegranat. The driving charge sleeve can of course be used for many purposes, and it can e.g. advantageously used as a firing sleeve for a throwing grenade.

Oppfinnelsen skal forklares nærmere under henvisning til tegningen som viser et foretrukket utførelseseksempel. The invention will be explained in more detail with reference to the drawing which shows a preferred embodiment.

På tegningen er metallbunnstykket betegnet med henvisningstallet 1. Ytterkan-ten til metallbunnstykket er betegnet med 2. Metallbunnstykket har en forlengelse 4 som er forsynt med spor 3. Metallbunnstykket er videre forsynt med en innpresset tennhette 5. Selve drivladningen 7 er anordnet inne i en kunststoffhylse 6. Kunststoffhylsen 6 er forankret i metallbunn-stykkets forlengelse 4, som antydet ved 3. Den slik frembragte forbindelse mellom kunststoffhylsen og bunnstykket kan mot-stå drivladnlngens eksplosjonstrykk. Tenningsforsterkeren 16 er anordnet i en kunststoffhylse 12 som er forankret i metallbunnstykket. In the drawing, the metal base piece is designated with the reference number 1. The outer edge of the metal base piece is designated with 2. The metal base piece has an extension 4 which is provided with a groove 3. The metal base piece is also provided with a pressed-in ignition cap 5. The propellant charge 7 itself is arranged inside a plastic sleeve 6. The plastic sleeve 6 is anchored in the extension 4 of the metal bottom piece, as indicated at 3. The connection thus created between the plastic sleeve and the bottom piece can withstand the explosive pressure of the propellant. The ignition amplifier 16 is arranged in a plastic sleeve 12 which is anchored in the metal bottom piece.

Legemet som skal avfyres, prosjektilet, er betegnet med 32, og det har en forlengelse 33 som omslutter kunststoffhylsen 6 med en viss klaring. I området ved bunn-stykkeforlengelsen 4 er det på kunststoffhylsen 6 anordnet en yttervulst 34 som utgjør en forsterkning av dette parti av hylsen. Prosjektilet holdes fast i forhold til drivladningshylsen ved hjelp av den ytre vulsten. Endeveggen 35 til kunststoffhylsen er utført med tykke vegger. Foran endeveggen er det i prosjektilhulrommet anordnet et tomt rom 36. Ved tenning vil det i området ved tenningsforsterkeren 16 hurtig oppstå et gasstrykk som vil rive av kunststoffhylsen umiddelbart foran ytter-vulsten 34. The body to be fired, the projectile, is denoted by 32, and it has an extension 33 which encloses the plastic sleeve 6 with a certain clearance. In the area of the bottom piece extension 4, an outer bead 34 is arranged on the plastic sleeve 6 which constitutes a reinforcement of this part of the sleeve. The projectile is held firmly in relation to the propellant casing by means of the outer bead. The end wall 35 of the plastic sleeve is made with thick walls. In front of the end wall, an empty space 36 is arranged in the projectile cavity. Upon ignition, a gas pressure will quickly arise in the area of the ignition amplifier 16 which will tear off the plastic sleeve immediately in front of the outer bead 34.
