Description

Divided chamber

Technical field

Firearms. Small-caliber weapons. Flobert type guns.

BACKGROUND OF THE INVENTION

The extraction of cartridges with a rim, especially in single-shot long rifle cartridges or flobert cartridges, is performed by a calendula extractor. The length of the active portion surrounding the cartridge closer to the edge and usually up to half the diameter of the cartridge is considerably shorter than the length of the cartridge. It is understood that the extractor by its structural configuration in the weapon and the position in the weapon is a detachable part of the cartridge chamber. The function of the extractor is most often kinematically derived from the linear movement of the slide slide or from the folding of the bundle of the weapon with a bed slide. A common disadvantage of the most commonly used extraction methods is the manufacturing complexity of the spatially articulated extractor. Another disadvantage is the possibility of leakage pressure leakage around the front of the extractor and the dividing plane, which is especially reflected in the cartridge with short cartridge and low energy, for example, the type of flobert. Another disadvantage is the difficulty of finishing assembly work when aligning the active marigold portion of the extractor so as to achieve alignment of the extractor with the chamber and the tightness at the point of contact of the extractor face with the chamber. The patented solution of Rudolf Oesterreich's 1886 repeater with a tubular cartridge under the barrel removes the extractor completely so that the cartridge chamber is half-slit along its length and the lower half is part of a swinging vertical breech. When charging the lower position of the swinging conclusion of the lower half of the cartridge chamber freely lying cartridge cartridges pushed a new cartridge from the cartridge box. This solution cannot be used with single-shot weapons without technical and economic complications.

The essence of the technical solution

These deficiencies are largely eliminated by a flobert or small-caliber cartridge barrel chamber equipped with a barrel-holster or barrel bore, divided by a plane along the longitudinal axis, identical to the longitudinal axis of the barrel bore, with the sliding and fixed parts, with sliding contact of the sliding part to the fixed part in the separation plane, with the length of the sliding part equal to at least the length of the cartridge and the maximum length of the hub, with the sliding part control kinematic derived from the action of the breech; fixed part with the sliding part extended.

A technical solution for a weapon with a barrel fixedly inserted into the receiver, with a half of the cartridge chamber made directly in the barrel and a sliding part of the cartridge chamber, controlled kinematic from the movement of the slide slide not shown here and with the cartridge inserted. The tiled contours show the position of the withdrawable portion of the cartridge chamber when extended for cartridge shell extraction, but still with a preferred partial contact in the separation plane with the fixed portion. Giant. 2 shows an example of a technical solution for a gun with a barrel fixedly mounted in a receiver, but with an expansion cavity to reduce charge energy and separate from a split cartridge chamber where half of the cartridge chamber is fixed firmly from the inside of the receiver; postponing the breech to extract the cartridge.

Example of technical solution

The split chamber for firearms for flobert or small-caliber rifle cartridges for guns with a bore 7 fixedly mounted in the housing 8 of the system consists of a fixed part 2, made directly in the barrel or a fixed part 2, Firmly enclosed within the holster 8 for weapons with reduced charge energy, and sliding part io of defined length 3, contacting the fixed part when extracting the cartridge at a defined length 4 with the fixed part in the division plane 6 and operated kinematic from the slide (not shown) 5. The function according to the technical solution and for the weapon with a slide slide is as follows:

After firing, the slide slide backwards is extended by sliding part I of the cartridge chamber by means of a member 5, which is kinematically coupled with the slide and sliding part of the cartridge chamber, into the cartridge chamber simultaneously with the cartridge. contact of the sliding part with the fixed part in length 4 prevents unwanted release of the sliding part away from the weapon.
