- 1 Conclusion with the barrel for the automatic pistol.

Technical field

The invention relates to a slide with a barrel for an automatic pistol comprising a body of a slide in which a barrel is located.

BACKGROUND OF THE INVENTION

When using a pistol for training or training purposes, it is advantageous to use low power ammunition for economic reasons. In terms of training efficiency, however, it is often necessary that the low-power ammunition pistol used is identical in shape to the standard-power ammunition gun used. This is achieved either by producing matched imitations adapted to use low power ammunition or by designing adapters to standard guns that eliminate the problems of low power ammunition in relation to the size and weight of the original breech. It is obvious that the use of adapters is cheaper than the design of the imitation gun.

The present solutions basically use either the principle of a split slide or a sliding chamber.

With a split slide, the desired effect is achieved by moving only a portion of the slide whose weight is proportional to the ammunition performance. A disadvantage of these embodiments is the considerable manufacturing complexity.

The sliding chamber is a device formed by a cylinder in which the cartridge chamber is located. The cylinder is slidably mounted in the barrel. When firing, gas pressure acts on the cylinder face, which discards the conclusion. The disadvantage of this solution is clogging of the whole device and consequently problematic function.

SUMMARY OF THE INVENTION

These drawbacks largely eliminate the breech barrel conclusion of the barrel body of the barrel of the present invention, which is based on a barrel enclosing a barrel in the body of the barrel. In the region of the chamber there is a protrusion on the barrel whose cross-section coincides with the cross-section of the chamber. At least one channel is formed in the barrel, connecting the bore barrel to the chamber.

Conclusion with the barrel of the invention acts as a recoil slider and allows the use of low power ammunition even with automatic guns, which normally operate with more powerful ammunition, while ensuring trouble-free pistol function even when using cartridges of inferior quality, without the risk of excessive contamination. The design also allows to imitate the movement of the weapon when firing consistent with the movement using more powerful ammunition.

For sufficient adaptation, it is advantageous if the starting position of at least one of the chamber faces is adjustable. This makes it possible to vary the velocity of the slide and thus to adapt the adapter to the charge with very different power.

Overview of the figures in the drawing

BRIEF DESCRIPTION OF THE DRAWINGS The invention will be explained in more detail with reference to the drawing of FIG. 1 shows an automatic pistol, with a breech and a barrel according to the invention in partial section.

DETAILED DESCRIPTION OF THE INVENTION

A known barrel is attached to the known automatic pistol as an adapter allowing the use of low-power ammunition, which is arranged such that a barrel 1 is formed in the barrel 4, which surrounds the barrel 5 and has a protrusion 2 on the barrel. The transverse cross-section of the projection coincides with the transverse cross-section of the chamber 1. From the bore 8, in particular 5, into the chamber 1 two channels 3.

After the firing, the flue gas flows from the bore 8, in particular 5, into the chamber 1, the pressure increase in the chamber 11 causing the slide body 4 to accelerate rearwardly.

In a preferred embodiment, the starting position of at least one of the faces 6, 7 of the chamber X is adjustable, which is achieved e.g. forming a projection 2 in the form of a screw imaginable on the barrel 5, or an imaginary structure of the rear side of the chamber i.

By varying the volume of the chamber 1, the breech function can be adapted to the flue gas pressure available with respect to the ammunition used.
