Abstract

The shell includes a propellent charge (13) for actuating a pressure plate (3) used to fire an active part (4) of the shell out of the barrel. The propellent charge is located inside a sleeve (1) containing a detonator cap (5) in the bottom. The sleeve is releasably connected to the pressure plate via a connecting tube (8) which contains an initial charge (17) and is connected to the detonator cap. The initial charge is used to disconnect a fastener (11) between the active part and pressure plate.

Description

funna 522 122 =.'j::j¿:.:¿: wiï= Tändskruven har en axiell kanal 7 som gör att tändhattens ver- kan kan löpa igenom tändskruven 6 uppåt i figuren. found 522 122 =. 'j :: j¿:.: ¿: wiï = The spark plug has an axial channel 7 which allows the action of the spark plug to run through the spark plug 6 upwards in the figure.

Hylsdelen 1 sammanbinds med tryckplattans 3 undersida medelst ett förbindelserör 8. Detta förbindelserör 8 innehåller en initialladdning 17. Initialladdningen 17 kan således antändas av tändhatten 5 via kanalen 7. Förbindelseröret 8 kan vara an- bringat vid tryckplattan 3 och mot tändskruven 6 medelst gäng- förbindning eller pressförbindning.The sleeve part 1 is connected to the underside of the pressure plate 3 by means of a connecting pipe 8. This connecting pipe 8 contains an initial charge 17. The initial charge 17 can thus be ignited by the ignition cap 5 via the channel 7. The connecting pipe 8 can be attached to the pressure plate 3 and to the ignition screw 6 by threaded connection or press connection.

På tryckplattans 3 ovansida är verkansdelen 4 fäst medelst ett lösbart fäste 11. Fästet kan bestå av en tapp 19 vid tryck- plattans 3 ovansida som fäster mot en hylsa 20 i verkansdelen 4. För att lösgöra förbindelsen mellan tappen 11 och hylsan 20 finns en kanal 10 genom tryckplattan vilken kanal står i för- bindelse med initialladdningen 17 i förbindelseröret 8 och vid initialladdningens antändning uppstår en tryckvåg som fort- plantar sig genom hålet 10 och så att säga spränger isär för- bindelsen mellan delarna 11 och 20. Olika konstruktioner för delarna 11 och 20 är härvid tänkbara för att åstadkomma lösgö- rande av förbindelsen. Vid utskjutningen skall således ver- kansdelen 4 vara lösgjord från tryckplattan 3 som genom an- läggning mot verkansdelen skjuter ut denna ur eldröret.On the upper side of the pressure plate 3 the action part 4 is fastened by means of a releasable bracket 11. The bracket may consist of a pin 19 at the upper side of the pressure plate 3 which attaches to a sleeve 20 in the action part 4. To loosen the connection between the pin 11 and the sleeve 20 there is a channel 10 through the pressure plate which channel is connected to the initial charge 17 in the connecting pipe 8 and when the initial charge ignites a pressure wave arises which propagates through the hole 10 and so to speak blows apart the connection between the parts 11 and 20. Different constructions for the parts 11 and 20 are conceivable in this case in order to effect detachment of the connection. During the firing, the impact part 4 must thus be detached from the pressure plate 3 which, by abutment against the action part, projects it out of the barrel.

Vidare har förbindelseröret 8 en anvisning 18 som i detta fall utgöres av en försvagning. Avsikten härmed är att få förbin- delseröret att brista så att sammanhållande kraften från för- bindelseröret för tryckplattan med hylsdelen brytes. I utrym- met runt förbindelseröret 8 inuti hylsdelen 1 finns en driv- laddning 13. Denna drivladdning 13 antändes därigenom att för- bindelseröret 8 har ett antal håligheter i cylinderväggen och medelst dessa håligheter antändes drivladdningen 13 så snart initialladdningen 17 av tändhatten 5 initierats. Drivladd- 7l915a.d0C; 2003-01-23 10 15 20 :unna _ .... ..".. ...un ¿g,: 1. . u. v. a I _ _ , , . n; nu au I I , 'I , , u IIOIUI ll O .Ü U I Il I OI I 5 5 ' 2 I I . . .. .. ..- | . . - a- ningen l3 kan bestå av en krutmassa eller till skivor utformad krutmassa som har centralt hål så att skivorna kan staplas på varandra inuti hylsdelen 1 med förbindelseröret utsträckt ge- nom centrala hålen i plattorna. På detta sätt kan olika antal plattor inläggas i beroende på önskad drivverkan från driv- laddningen.Furthermore, the connecting pipe 8 has an instruction 18 which in this case consists of a weakening. The purpose of this is to cause the connecting pipe to rupture so that the cohesive force from the connecting pipe for the pressure plate with the sleeve part is broken. In the space around the connecting pipe 8 inside the sleeve part 1 there is a propellant charge 13. This propellant charge 13 is ignited in that the connecting pipe 8 has a number of cavities in the cylinder wall and by means of these cavities the propellant charge 13 is ignited as soon as the initial charge 17 of the spark plug 5 is initiated. Drivladd- 7l915a.d0C; 2003-01-23 10 15 20: unng _ .... .. ".. ... un ¿g ,: 1.. Uv a I _ _,,. N; nu au II, 'I,, u IIOIUI ll O .Ü UI Il I OI I 5 5 '2 II.. .. .. ..- |.. stacked on top of each other inside the sleeve part 1 with the connecting pipe extending through the central holes in the plates, in this way different numbers of plates can be inserted depending on the desired driving action from the driving charge.

Vid drivladdningens 13 detonering brister således förbindelse- röret 8 genom försvagningen 18 så att tryckplattan 3 kan fri- göras från hylsdelen l och lösgjord från verkansdelen skjuta denna framför sig ut ur eldröret.During the detonation of the propellant charge 13, the connecting tube 8 thus breaks through the weakening 18 so that the pressure plate 3 can be released from the sleeve part 1 and detached from the operative part, pushing it in front of it out of the fire tube.

Tidigare av beskrivningen och i ritningsfiguren anvisas en brottsanvisning på förbindelseröret 8 i form av en förtunning av förbindelserörets vägg. Emellertid kan brottsanvisningen vara i annan form t.ex. i förbindelserörets ovanände där för- bindelseröret 8 är anbringat mot tryckplattans 3 undersida.Earlier in the description and in the drawing figure, a break instruction is indicated on the connecting pipe 8 in the form of a thinning of the connecting pipe wall. However, the criminal instruction can be in another form e.g. at the top of the connecting pipe where the connecting pipe 8 is attached to the underside of the pressure plate 3.

Brottsanvisningen kan där bestå i av försvagade gängor eller form av brytpinne. Uttrycket brottsanvisning skall alltså för- stås som en generell beteckning för någon form av koppling som kan brista av tryckpåverkan eller dragpåverkan. Vidare kan förbindelseröret 8 i sin helhet vara utformat av material som brister pà grund av kraften från drivladdningens detonering.The crime instruction can there consist of weakened threads or a form of breaking pin. The term criminal instruction must thus be understood as a general term for some form of coupling that may be lacking in the effect of pressure or traction. Furthermore, the connecting pipe 8 may in its entirety be formed of material which is defective due to the force of the detonation of the propellant charge.

Tänkbart är således ett rör av t.ex. plast. Detta påverkas t.ex. redan vid initialladdningens antändning så att dess draghållfasthet blir minimal när drivladdningen detonerar. 7l915a.dOC; 2003-01-23Conceivable is thus a tube of e.g. plastic. This is affected e.g. already at the initial charge ignition so that its tensile strength is minimal when the propellant charge detonates. 7159a.dOC; 2003-01-23
