Description

La présente invention concerne un accessoire pour pistolet à canon mobile, équipé d'un dispositif d'étanchéité.The present invention relates to an accessory for a mobile gun, equipped with a sealing device.

Il est parfois souhaité d'équiper un pistolet du type à canon et glissière mobiles d'un accessoire tel qu'un silencieux par exemple. Il se pose alors le problème de l'étanchéité entre ledit accessoire et le canon, entre le moment du départ du coup et la sortie de la balle de l'accessoire, ceci afin de ne pas nuire à l'efficacité de ce dernier.It is sometimes desired to equip a pistol of the movable barrel and slide type with an accessory such as a silencer for example. There then arises the problem of the seal between said accessory and the barrel, between the moment of the start of the shot and the exit of the bullet from the accessory, this in order not to harm the effectiveness of the latter.

Le but de l'invention est de fournir une solution adéquate à ce problème.The object of the invention is to provide an adequate solution to this problem.

A cet effet, il est proposé un accessoire pour pistolet à canon mobile, destiné à être fixé à ce dernier en alignement avec l'axe dudit canon, caractérisé en ce qu'il est équipé d'un dispositif d'étanchéité constitué par deux bagues, l'une fixe et l'autre mobile, insérées dans ledit accessoire et définissant entre elles une chambre, ladite bague mobile étant destinée à être appliquée contre ledit canon - respectivement contre la face avant de ladite glissière - lors du tir, par l'action des gaz dans ladite chambre.To this end, an accessory for a mobile gun is proposed, intended to be fixed to the latter in alignment with the axis of said barrel, characterized in that it is equipped with a sealing device constituted by two rings , one fixed and the other mobile, inserted into said accessory and defining between them a chamber, said mobile ring being intended to be applied against said barrel - respectively against the front face of said slide - during firing, by the action of gases in said chamber.

Les particularités et avantages de l'invention apparaîtront plus clairement de la description ci-après d'un exemple non restrictif de mise en oeuvre, référence étant faite aux dessins annexés dans lesquels :

  • la figure 1 est une vue schématique d'un pistolet à canon mobile équipé d'un accessoire selon l'invention, montré partiellement et en coupe axiale; et
  • la figure 2 est une vue explosée des éléments constitutifs du dispositif d'étanchéité équipant ledit accessoire.
The features and advantages of the invention will become apparent more clearly from the description below of a non-restrictive example of implementation, reference being made to the appended drawings in which:
  • Figure 1 is a schematic view of a movable barrel gun equipped with an accessory according to the invention, shown partially and in axial section; and
  • Figure 2 is an exploded view of the components of the sealing device fitted to said accessory.

Comme représenté à la figure 1, un accessoire 1 selon l'invention - en l'occurrence un silencieux - est fixé par une bride 2 à la carcasse 3 d'un pistolet à canon 4 et glissière 5 mobiles. Il s'agit ici d'un pistolet du type à court recul de canon.As shown in Figure 1, an accessory 1 according to the invention - in this case a silencer - is fixed by a flange 2 to the carcass 3 of a gun pistol 4 and slide 5 movable. This is a short recoil type pistol.

L'accessoire 1 comporte un alésage axial ou âme 6 dans laquelle est fixée une bague fixe 7 pourvue d'une queue tubulaire 8. Autour de cette dernière est glissée une bague mobile 9 présentant un rebord ou lèvre 10.The accessory 1 comprises an axial bore or core 6 in which is fixed a fixed ring 7 provided with a tubular tail 8. Around the latter is slid a movable ring 9 having a rim or lip 10.

Entre les bagues fixe et mobile et autour de ladite queue 8 est monté un ressort 11, refoulant la bague mobile 9 contre la glissière 5. La queue tubulaire 8 est pourvue d'une pluralité d'orifices 12 de passage des gaz.Between the fixed and movable rings and around said tail 8 is mounted a spring 11, driving the movable ring 9 against the slide 5. The tubular tail 8 is provided with a plurality of orifices 12 for the passage of gases.

La paroi interne de l'alésage 6, la bague 7, la paroi externe de la queue 8 et la lèvre 10 de la bague mobile 9 définissent entre elles une chambre à gaz 13 accessible via lesdits orifices 12.The internal wall of the bore 6, the ring 7, the external wall of the tail 8 and the lip 10 of the movable ring 9 define between them a gas chamber 13 accessible via said orifices 12.

Au repos, le ressort 11 applique la bague 9 contre la glissière 5. Lors du tir, les gaz encore à pression élevée pénètrent dans.la chambre 13 et agissent contre la lèvre 10 pour refouler la bague 9 laquelle accompagne le mouvement de recul de la glissière 5, respectivement du canon 4, assurant ainsi l'étanchéité.At rest, the spring 11 applies the ring 9 against the slide 5. During the firing, the gases still at high pressure penetrate dans.la chamber 13 and act against the lip 10 to push back the ring 9 which accompanies the recoil movement of the slide 5, respectively of the barrel 4, assu thus sealing.

Le tarage du ressort 11 est choisi très nettement plus faible que celui du ressort récupérateur de l'arme, de sorte à ne pas perturber le fonctionnement de cette dernière. Pour cette même raison la surface de la lèvre 10 est choisie de sorte à ce que la bague mobile 9 n'exerce sur la glissière 5, lors du tir, qu'une force juste nécessaire à assurer l'étanchéité.The calibration of the spring 11 is chosen very much lower than that of the recuperator spring of the weapon, so as not to disturb the operation of the latter. For the same reason the surface of the lip 10 is chosen so that the movable ring 9 exerts on the slide 5, during firing, only a force just necessary to ensure the seal.

Diverses modifications peuvent évidemment être apportées à l'exemple susdécrit, sans pour autant sortir du cadre de l'invention.Various modifications can obviously be made to the example described above, without going beyond the ambit of the invention.

Ainsi, entre autres, lesdits orifices 12 pourraient être omis et leur rôle rempli par un jeu adéquat entre la bague mobile 9 et ladite jupe 8.Thus, among others, said orifices 12 could be omitted and their role fulfilled by an adequate clearance between the movable ring 9 and said skirt 8.
