Description
15 20 25 30 35 810ö869-0 Kända bottenbrickor består vanligen av gunsni, plast, bakelit, pappers- laminat e d, relativt bristbart material. Inget av dessa material uppvisar dock alla de ovannämnda egenskaperna. 15 20 25 30 35 810ö869-0 Known bottom trays usually consist of gunsni, plastic, bakelite, paper laminate etc., relatively defective material. However, none of these materials exhibits all of the above properties.
Ehuru dessa egenskaper sedan länge är kända hos härdat glas, så har man hittills icke ansett det möjligt att föreslå användning av detta material i fördämningsbrickor, framför allt med hänsyn till att det knappast kan förväntas att glas skulle vara tillräckligt motstånds- kraftigt för att motstå de initialtryck som drivladdningen uppbygger i förbränningsnmsnet. Härdat glas har därför hittills endast kunnat föreslås som material i t e: rörliga motmassor o d, vilka av driv*- laddningens förbränningsgaser trycks ut genom eldrörets bakre del, där de splittras mot ett anslag, se t ex den amerikanska patent- skriften 4.132.148. Däremot har man icke ansett det meningsfullt att föreslå glas såsom material i en i ett förbränningsruan fast inspänd fördämningsbricka, som i inspänt tillstånd skall motstå ett visst initialtryek och därefter splittras.Although these properties have long been known in tempered glass, it has not hitherto been considered possible to propose the use of this material in dams, especially in view of the fact that glass can hardly be expected to be sufficiently resistant to withstand the initial pressure that the propellant charge builds up in the combustion nozzle. Tempered glass has therefore so far only been proposed as a material in, for example, movable countermasses, etc., which of the combustion gases of the propellant charge are forced out through the rear part of the barrel, where they split into a stop, see for example U.S. Pat. No. 4,132,148. On the other hand, it has not been considered meaningful to propose glass as a material in a dam which is clamped in a combustion window, which in the clamped state must withstand a certain initial pressure and then split.
REDOGÖRELSE FÖR UPPFINNINGBN Föreliggande uppfinning bygger nu på den överraskande upptäckten att härdat glas i strid mot vedertagna teorier kan användas även som material i fast inspända fördämningsbrickor.DESCRIPTION OF THE INVENTION The present invention is now based on the surprising discovery that tempered glass, contrary to accepted theories, can also be used as a material in clamped dam washers.
BESKRIVNING AV RITNINGSFIGURERNA Uppfinningen komer närmare att beskrivas nedan under hänvisning till ritningen där en föredragen utföringsform av fördämningsbrickan enligt uppfinningen visas i två olika samanhang, nämligen i figur 1, där brickan utgör bottendel i en patronhylsa ingående i anmxnition för ett rekylfritt vapen, och i figur 2, där brickan är inspänd i eldröret på ett rekylfritt vapen, som är avsett för hylslös amuni- tion.DESCRIPTION OF THE DRAWINGS The invention will be described in more detail below with reference to the drawing where a preferred embodiment of the dam washer according to the invention is shown in two different contexts, namely in figure 1, where the washer forms a bottom part of a cartridge case included in a recoil-free weapon. 2, where the washer is clamped in the barrel of a recoilless weapon, which is intended for sleeveless ammunition.
FÖREDRAGEN UTFÖRINGSFORM I figur 1 visas schematiskt ett rekylfritt vapen av konventionell typ, innefattande ett eldrör l, i vilket en projektil 2 är införd i ett laddläge. Projektilen 2 är fastsatt i en patronhylsa 3, som på känt sätt inryusner en drivladdning lo och en anfyrningsladd- 10 15 8100869-0 ning 5, vilken är anordnad att kunna initieras från sidan av en avfyringsanordning 6. Hylsans 3 bakre vägg, som lr fast inspänd i hylsan 3, utgöra av en fördlmningsbricka 7, som enligt uppfinningen består av härdat glas.PREFERRED EMBODIMENT Figure 1 schematically shows a recoilless weapon of conventional type, comprising a barrel 1, in which a projectile 2 is inserted in a charging position. The projectile 2 is fixed in a cartridge sleeve 3, which in a known manner encloses a propellant charge 10 and a firing charge 5, which is arranged to be initiated from the side of a firing device 6. The rear wall of the sleeve 3, which is fixed clamped in the sleeve 3, constitute a partition washer 7, which according to the invention consists of tempered glass.
I figur 2 visas schematiskt ett rekylfritt vapen av konventionell typ, innefattande ett eldrör 11, i vilket en hylslös projektil 12 är införd i ett laddläge. Bekom projektilen 12 finns ett gastätt tillslutet förbränningsrum, som begränsas framåt av projektilen 12, åt sidorna av eldröret ll och bakåt av en i eldröret fast inspänd fördämningsbricka 17 av härdat glas. I förbränningsrumet är anordnad en drivladdning 14 och en anfyrningsladdning 15, vilken är avsedd att tändas från sidan av en konventionell avfyringsanordning l6.Figure 2 schematically shows a recoilless weapon of conventional type, comprising a barrel 11, in which a sleeveless projectile 12 is inserted in a charging position. Once the projectile 12 is present, there is a gas-tight closed combustion chamber, which is limited forwards by the projectile 12, to the sides of the barrel 11 and to the rear by a dam 17 of tempered glass fixed in the barrel. Arranged in the combustion chamber are a propellant charge 14 and a firing charge 15, which is intended to be ignited from the side of a conventional firing device 16.
De olika i det rekylfria vapnet och i ammunitionen ingående kompo- nenterna är av konventionell typ och utgör, bortsett från fördäm- ningsbrickan, ej del av föreliggande uppfinning. Det har därför ansetts tillräckligt med ovannämnda schematiska beskrivning därav.The various components included in the recoilless weapon and in the ammunition are of a conventional type and, apart from the dam washer, do not form part of the present invention. It has therefore been considered sufficient with the above-mentioned schematic description thereof.
