Abstract

The invention relates to a mass lockable weapon closure system (1) having a closure part (3) which can be displaced in a closure housing (2) of a corresponding weapon and an elastic closure element (12). In order for such a closure system (1) to have a high level of functional reliability and to ensure that the firing of powerful ammunition is not associated with any substantial increase in the weight of the corresponding weapon, the invention proposes to integrate the closing element (12) into the closure part (3). It is achieved by a with the closing element (12) in series and also in the closure part (3) arranged hydraulic translation that the closing element (12) can be made very short and the spring characteristic can have a flat increase in force.

Description

The invention relates to a mass locking weapon locking system with a lockable in a closure housing a corresponding weapon lockable part and an elastic closure element.

In automatic or semi-automatic weapons with mass lockable closure system, the weapon barrel of the corresponding weapon is closed at the rear by a heavy closure part (closure block), wherein the closure part is slidably disposed in a locking housing of the weapon axially adjacent to the weapon barrel and by an elastic closing element (Vorholer), in which it is usually a closing spring, is acted upon (see, for example: Rheinmetall "Weapon Technique Paperback", Dusseldorf, 7th Edition 1985, pages 248 ff).

For firing powerful ammunition you need in the known mass-locking locking systems both a heavy lock block and a strong closing spring. This leads when using long closing springs to increase the weight of the corresponding weapon or the spring characteristic of the respective closing spring must have a steep increase in force. In addition, the closing springs are exposed in the known closure systems environmental influences and can easily pollute.

The invention has for its object to provide a mass-lock system, which ensures high reliability and which is also connected to the firing of high-performance ammunition with no significant increase in weight.

The US 2006/0185507 A1 discloses a hydraulic shut-off system having a low pressure accumulator and a high pressure accumulator for fluids, both of which functionally cooperate with each other. The low-pressure accumulator and the high-pressure accumulator are separated from each other.

From the DE 600 05 303 T2 is a device for reducing the recoil with brake, Bremskompensator and Rohrvorholer known.

The US 5,060,555 A relates to a recoil damper of a weapon with a sliding delay, comprising a cylindrical cavity and a deformable mass of elastomer. A piston provided with a rod is slidably mounted in the cavity. The elastomer consists of a cylindrical plug.

This object is achieved by the features of claim 1. Further, particularly advantageous embodiments of the invention disclose the dependent claims.

The invention is based essentially on the idea of integrating the closing element in the closure part. It is achieved by a connected in series with the closing element and also arranged in the closure part hydraulic translation that the closing spring can have a relatively small length and its characteristic only a relatively flat increase in force.

For the realization of the closure system according to the invention, the closure part is not designed as a solid closure block, but as a hollow cylinder, wherein the cylinder space is divided by an axially displaceable balance piston into two partial cylinder spaces. In this case, in the direction of firing of the corresponding weapon, arranged on the rear side and filled with a brake fluid first partial cylinder space arranged an axially displaceable piston which is connected to a piston rod which passes axially through the rear wall of the closure member and at its end facing away from the piston is connected to the closure housing. In the second part of the cylinder space, the elastic closing element is arranged, which holds the balancing piston in a starting position, such that when the closing part returns by the piston moving into the first partial cylinder space, the compensating piston is moved towards the closing element and the closing element is tensioned.

Since the closing element and the components of the hydraulic transmission components of the required anyway returning mass, an increase in the total weight of the corresponding weapon can be avoided.

In addition, the closure system according to the invention has the advantages that the closing element is well encapsulated and therefore environmental influences have only a small influence on this element. In addition, it has been shown that this closure system has a high reliability and the clamping force of the closing element is very constant.

The closing element is preferably a compression spring, which is supported with its one end on the balance piston and with its other end on the front wall of the closure part.

Advantageously, the rear-side partial cylinder space together with the piston and the piston rod form a plunger cylinder (plunger cylinder), ie a cylinder in which the Piston rod also serves as a piston, so that the cylinder is characterized by a simple and robust structure.

Further details and advantages of the invention will become apparent from the following, with reference to figures explained embodiments. Show it:

1 the longitudinal section of a schematically illustrated weapon locking system according to the invention with a arranged in a weapon housing closure member in its initial position;

2 this in 1 Shutter system shown, after firing at the end of the return of the closure part and

3 this in 1 illustrated locking system during the flow to its starting position.

In the 1 to 3 is with 1 a mass-locking weapon locking system called, which in a closure housing 2 is arranged, which adjoins the rear of the cartridge chamber of a gun barrel, not shown.

The weapon locking system 1 essentially comprises a in the closure housing 2 axially displaceable closure part 3 which also contains the elements not shown for reasons of clarity, required for firing and removing the cartridge after firing.

The closure part 3 is designed as a hollow cylinder, wherein the cylinder space 4 by an axially displaceable balance piston 5 in two partial cylinder chambers 6 . 7 is divided.

The one seen in firing direction of the corresponding weapon (indicated by the arrow 100 ), rear side arranged first partial cylinder space 6 is with a brake fluid (usually oil) 8th filled. In addition, in the first partial cylinder space 6 an axially displaceable piston 9 arranged with a piston rod 10 connected is. The piston rod 10 is axial through the rear wall 11 of the closure part 3 passed and is at her the piston 9 opposite end with the closure housing 2 connected.

As can be seen from the figures form the first partial cylinder space 6 together with the piston 9 and the piston rod 10 a plunger cylinder.

In the second (front) partial cylinder space 7 is an elastic closing element 12 arranged, which is a formed as a compression spring closing spring. The closing spring 12 relies on one end 13 on the balance piston 5 and with their other end 14 on the front wall (impact floor) 15 of the closure part 3 from.

Below is with the help of 1 to 3 closer to the operation of the weapon locking system according to the invention 1 received:
In the in 1 illustrated starting position of the closure system 1 is the closure part 3 in its forward position. This is the brake fluid 8th in the first partial cylinder space 6 through the closing spring 12 over the balance piston 5 biased. With this pressure force is over the surface of the cross section of the piston rod 10 this from the closure part 3 - and thus the closure part 3 against a stop 16 in the weapon case 2 - pressed.

When firing a (not shown) cartridge, the propellant charge gases act on the, shock bottom 15 of the closure part 3 , This leads to an acceleration of the closure part 3 against the weft direction and thus to a movement of the closure part 3 in the return direction.

This increases the pressure in the first partial cylinder space 6 by the displaced volume of the retracting piston 9 so that the balance piston 5 from the brake fluid 8th is moved and the closing spring 12 continues to stretch.

After the return of the closure part 3 is completed ( 2 ), becomes the closure part 3 through the on the balance piston 5 acting force of the closing spring 12 moved in firing direction ( 3 ) until it has returned to its starting position ( 1 ).

As an elastic closing element can instead of, for example, the closing spring 12 an elastic rubber and / or plastic part (bulky) or a gas spring or compressible gas can be used.

In case of using rubber / plastic part, the balance piston 12 omitted in the form described, since then the brake fluid facing side of the rubber or plastic part can take over its function.
