Title
(EN) BARREL CLOSING MECHANISM FOR A SMALL-SIZED AUTOMATIC ARM
(FR) MÉCANISME DE VERROUILLAGE DU CANON DESTINÉ À UNE ARME AUTOMATIQUE PORTATIVE
(RU) ЗАПИРАЮЩИЙ МЕХАНИЗМ СТВОЛА МАЛОГАБАРИТНОГО АВТОМАТИЧЕСКОГО ОРУЖИЯ
Abstract
(EN)
The invention relates to weapons, in particular to automatic fire arms, mainly to small arms, in particular to barrel closing mechanisms. The inventive barrel closing mechanism comprises a bolt which is placed in a barrel extension (1) which is connected to a back-moving spring. Said spring is embodied in the form of a torsion spring, is pivotally fastened on the barrel extension (2) and is freely connected to the bolt. Said invention makes it possible to improve the mass, size and energetic parameters of fire arms without complicating the structural design therefor.
(FR)
L'invention concerne le domaine de l'armement et notamment des armes à feu automatiques, et plus particulièrement des armes de petit calibre; elle concerne notamment des mécanismes de verrouillage du canon. Le mécanisme de verrouillage comprend une culasse (1) disposée dans le raccord de canon et reliée à un ressort de retour. Le ressort est un ressort de torsion, monté par charnières dans le raccord de canon (2) et relié librement à la culasse. L'invention permet d'améliorer les caractéristiques d'une arme à feu en termes de masse, de dimensions et d'énergie sans rendre sa structure plus complexe.

Изобретение относится к области вооружения, в частности, к автоматическому огнестрельному оружию, преимущественно стрелковому, а именно к запирающим механизмам ствола. Запирающий механизм ствола, включает в себя размещенный в ствольной коробке затвор (1), связанный с возвратной пружиной. Пружина выполнена в форме пружины кручения и закреплена на ствольной коробке (2) шарнирно, а с затвором связана свободно. Изобретение обеспечивает улучшение массо-габаритных и энергетических параметров огнестрельного оружия без усложнения конструкции.
