Definitions

  • the arms system generalised under a title "hyrojet” allowing usage in shooting weapon is known, namely - ammunitions - aerodynamic stabilisers as folding wings, which considerably increase resistance, limiting shell flight velocity.
  • the starting device is made from duralumin alloy as a pistol (carbine), where the ignition takes place next way: the striker located before a shell in a cocked condition, knocks at a shell nose, moving it back where is located the firing pin, which pins ignition cap located in a shell back part. Striker resetting takes place when a shell moves forwards. The delivery is carried out from constant magazine, which filling happens through the special window by one shell.
  • the imperfection of that system is the low kinetic energy of a shell on small distances, as the propellant burning time makes 0,12 seconds.
  • the invention problem is the design of the device of automatic breech-block unlocking, permitting to use energy of accumulated gun-powder gases for the weapon reload and prevent the weapon reload in a moment when the bullet has not gone out yet from barrel channel.
  • the second variant of the device of automatic breech-block unlocking contains the main chamber 1 , communicated with the weapon barrel 2 channel through the vent 3 in the barrel 2 wall, piston 4 placed in the main chamber 1, additional chamber 5 communicated with the weapon barrel 2 channel through an additional vent 6 in the barrel 2 wall.
  • the valve 7 with a spring 8 is adjusted.
  • the blocking element 9 is located.
  • the valve 7 is executed as a hollow cylindrical element, in which lateral wall the vent 10 superposed to an additional vent 6 in the barrel 2 wall is executed, and the spring 8 is placed between a base part of the cylindrical element and frontal wall of the additional chamber 5.
  • the bullet 11 is represented.
  • the closed valve 6 does not permit gases accumulated in the chamber 7 to pass through the vents in the transversal wall 5 and they influencing, on the one hand, on the barrel ledge 11, and on the other hand on the transversal wall 5, cause the moving back of breech-block carrier 12 together with the breech-block 3 and opening of the barrel channel, then the reload of the weapon takes place.
  • the second device variant works as follows.
  • gun-powder gases After passing of a bullet 13 by an additional vent 7 in the barrel 2 channel gun-powder gases fill in the additional chamber 6 and, influencing lock element, 8 move it.
  • gun-powder gases After passing of a bullet 13 by the vent 3 in the barrel 2 wall gun-powder gases pass into the main chamber 1, filling in the cylindrical element 10 hollow, which is the valve, through the vent 12 in a lateral wall of the cylindrical element superposed to the vent 3 in the barrel 2 wall.
  • Gun-powder gases, filling in the cylindrical element 10 hollow influence the piston 4 and base part of the cylindrical element 10.
  • the mentioned device variants can be equipped shooting and artillery weapon in which both simple and jet shells are used.
  • the weapon safety is improved as the reload takes place only after a bullet or shell gone out from the barrel channel.

Abstract

L'invention concerne la mise au point d'armes, et plus précisément les dispositifs à déverrouillage automatique du bloc de culasse actionné par l'énergie des gaz accumulés après combustion de la poudre. Selon un premier mode de réalisation, le dispositif à déverrouillage automatique du bloc de culasse comporte la chambre principale (4) et une chambre supplémentaire (7), toutes deux situées entre une surface extérieure du canon (1) de l'arme et le support (12) du bloc de culasse qui enveloppant le canon (1) et qui est fixé de façon rigide au bloc (3) de culasse. Le canon présente des rebords (10 et 11) et la chambre principale (4) communique avec l'âme du canon (1) par l'intermédiaire de l'évent (2) ménagé dans la paroi du canon (1). La paroi transversale (5), pourvue d'évents et d'un clapet, est disposée entre la chambre principale (4) et la chambre supplémentaire (7). Selon un deuxième mode réalisation, le dispositif à déverrouillage automatique du bloc de culasse comporte la chambre principale (1) avec le piston, laquelle communique avec l'âme du canon (2) par l'intermédiaire de l'évent (3) ménagé dans la paroi du canon (2), et une chambre supplémentaire (5) pourvue du clapet (7) et du ressort (8), laquelle communique avec l'âme du canon (2) par l'intermédiaire d'un évent (3) supplémentaire ménagé dans la paroi du canon (2). Selon un troisième mode de réalisation, le dispositif à déverrouillage automatique du bloc de culasse comporte la chambre principale (1), laquelle communique avec l'âme du canon (2) par l'intermédiaire de l'évent (3) ménagé dans la paroi du canon (2), chambre (1) où sont d'ailleurs placés le piston (4) et le ressort (5). Selon un quatrième mode de réalisation, le dispositif à déverrouillage automatique du bloc de culasse comporte la chambre principale (1) et des chambres supplémentaires (6) communiquant toutes avec l'âme du canon (2) par l'intermédiaire d'évents (3) et (7) ménagés dans la paroi du canon (2), le piston (4), le clapet (10) et le ressort (11) étant placés dans la chambre principale (1), un élément (8) de verrouillage, situé dans les chambres supplémentaires (6) étant fixé avec une possibilité d'interaction sur un rebord (9) pratiqué sur une tige (5).
