Description
Znane sa ogólnie wszystkie wady istnie¬ jacych pirotechnicznych zabezpieczen pro¬ chu, jak np. odksztalcenie sie tloka bez¬ piecznikowego przy tloczeniu, jego zacina¬ nie sie, niedostateczna szczelnosc, wielki o- pór podczas ruchu, niewygodny montaz i L d.Wszystkie te wady usuwa przyrzad wy¬ konany w mysl wynalazku, który dotyczy pirotechnicznego bezpiecznika przeciw wy¬ buchom pocisku w lufie, który to bezpiecz¬ nik, jak widac na rysunku, sklada sie z la¬ dunku prochu 4, który musi sie predzej za¬ palic, nim plomien z kapsli zapalowej mo¬ ze sie przeniesc dalej na wlasciwy ladunek pocisku. Czesc bezpiecznikowa / wykona¬ na jest w ksztalcie kuli, która ze znacz¬ nym luzem 2 osadzona jest w lozysku 3 zsl- bezpieczajacego ladunku prochu 4, przy- czem kulka przylega szczelnie do gniazda 5, wyikonanego z miekszego materjalu niz kulka /. Przy sciskaniu zabezpieczajacego ladunku prochu gniazdo 5 przyjmuje do¬ kladny ksztalt kuli /, przez co zapewnione jest zupelne uszczelnienie.Na kulce 1 opiera sie czop 6 uderzaka bezpiecznikowego 7, który utrzymuje sie w polozeniu zabezpieczonem. PL PLAll the disadvantages of the existing pyrotechnic safety devices are generally known, such as, for example, the deformation of the safety piston during pressing, its jamming, insufficient tightness, great movement resistance, inconvenient assembly, and all. the disadvantages are eliminated by a device according to the invention which relates to a pyrotechnic fuse against projectile explosion in a barrel, which fuse, as can be seen from the drawing, consists of a powder landing 4 which must first burn, before the flame from the igniting cap can travel on to the proper charge of the projectile. The fuse part / is made in the shape of a ball, which, with a considerable play 2, is embedded in the bearing 3 securing the powder charge 4, with the connection the ball adheres tightly to the seat 5, made of a material softer than the ball /. When squeezing the protective powder charge, the seat 5 assumes the exact shape of a ball (thereby ensuring a complete seal. The ball 1 rests on a pin 6 of the fuse striker 7, which is held in a secured position). PL PL
