Description

Technical area

The invention relates to a gun with a mass-locked locking system, which comprises a displaceably mounted in a frame assembly closure member. In order to reduce the recoil forces, the installation of a recoil damper is provided. By incorporating the recoil damper, the momentum that occurs when firing a projectile is converted into a more uniform controlled motion. Furthermore, the movement sequence of the closure can be positively influenced and the occurring motion impulses can be coupled from the frame assembly.

State of the art

In automatic or semi-automatic weapons, the tube is closed after feeding a cartridge with a closure part backward. Usually come here so-called delayed mass closures are used, all meet the feature that they only reopen the pipe, who the bullet has already left the run or is about to. After unlocking the closure part of this runs driven by the residual pressure in the barrel or forcibly controlled by withdrawn from the barrel strained gas in the closure housing to the rear, with a closing spring counteracts the return force. The return is then stopped when reaching the necessary travel path through a rear stop in the housing. When returning, the empty cartridge case is ejected. After the closure has been stopped, the closing spring ensures that the closure is pushed back towards the barrel. As the shutter advances, it removes a new cartridge from the magazine and slides it into the chamber. The forward movement of the closure is stopped by impacting the closure on components of the cartridge chamber.

Rebound brakes are known as such. That's how it describes DE 60 2005 00 575 T2 ( EP 1 591 742 B2 ) a hydraulic recoil damper, wherein the rod is fixed to a bottom piece sleeve and the damper body on the solid support of the weapon.

Another recoil damping describes the DE 10 2007 003 180 B4 , The recoil damping used herein acts between a ramen assembly and a barrel assembly and is disposed axially between a bumper region of the barrel assembly and a support portion of the frame assembly.

Another weapon return system describes the DE 10 2009 039 039 A1 , This consists of a pressure vessel and a pressure cylinder with pressure piston. The gun barrel end is connected to the plunger cylinder for compression of a gas cushion in the impression cylinder. The pressure piston is designed so that when returning a large cross-section for the flow of liquid and the tube reclaiming a small cross-section is open.

Another recoil damping for grounding closures describes the DE 10 2012 022 682 B8 , This consists of a closure part by a brake system is integrated, which is supported by the rear wall of the closure part by means of a piston rod from the closure housing.

Presentation of the invention

The invention is based on the object to convert the recoil impulse occurring by the firing of a projectile into a more pleasant for the shooter linear motion. Furthermore, the invention is intended to ensure a significant improvement in the handling of the occurring acceleration and impact forces of common closure systems, with a good possibility of integration into different weapon types is a prerequisite. In order to enable integration of a recoil damper in pipe guns with short runs or compact construction masses, the inventor proposes a new configuration of moving in the gun weapon components.

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

Another advantage of the invention is that by smoothing the acceleration pulses can avoid loading errors that occur when exceeding the permissible average closing speed, triggered by fluctuations in the propellant charge.

A further advantage of the invention is that the cadence of the weapon can be influenced by changing the damping characteristic.

Another advantage of the invention is that can be significantly reduced using the recoil damper assembly according to the invention and version with lafettier Barem run especially for larger calibers the weapon weight.

Brief description of the drawings

Other objects, features, advantages and applications of fiction moderate Rebound damper arrangement will become apparent from the following descriptions of exemplary embodiments with reference to the drawings. All the features illustrated, alone or in any combination, form the subject matter of the invention, regardless of the summary in individual claims or inference.

In the drawings show

1 the longitudinal section of a tube weapon shown schematically and the inventive standard arrangement of the recoil damper unit in the starting position before firing.

2 the longitudinal section of a tube weapon shown schematically and the recoil damper unit according to the invention after firing.

Embodiment of the invention

In the 1 to 2 is with 1 a partial section of a tubular weapon schematically shown, which is shown in longitudinal section, which is a mass-lockable closure part 2 that in a lock housing 17 which is slidably integrated in a frame assembly 9 is stored and the front of the not shown in detail cartridge chamber of the barrel 13 followed. It is with reference numerals 100 the barrel axis and weft direction marked and gives the formulation used in the texts in the front, the direction.

The closure part 2 It basically includes all the components needed to lock to the barrel, fire the cartridges, and remove the cartridge after firing, ejecting the cartridge, and reloading with a new cartridge. These are not shown to simplify the drawing.

In the 1 to 2 shows the barrel assembly 13 . 1.13 . 2.13 the over the housing part 1.13 axially displaceable with the frame assembly 9 connected is. The chamber housing 2.13 the barrel assembly is also axially displaceable in the closure housing 17 or the frame assembly out.

The frame assembly 9 essentially comprises all components such as handle magazine holder, trigger unit and others, was waived their representation to simplify the drawing.

In 1 and 2 With reference number 110 the effective direction of the recoil is marked and gives the formulation used in the texts behind, the reverse direction.

When firing a cartridge (not shown), the explosion pressure of the propellant acts on the front of the closure 2 , This leads to an acceleration of the closure part 2 against the weft direction 100 and the return movement 110 Is initiated. As long as the closure part 2 is locked with the barrel assembly, the return movement is transmitted to the barrel assembly, this in turn rests with the housing part 1.13 on the piston rod 3 of the recoil damper, while the recoil damper acts with its internal resistance, as well as the elastic spring element 10 the recoil force. When returning the piston rod 3 the recoil damper further into the cylinder 4 pushed, the thereby displaced liquid 11 (Oil) flows through at least one control port 6 into the liquid collecting space 8th and over the compensation hole 16 in the front cylinder chamber 14 , The difference volume from the volume of the cylinder space 4 and the front cylinder chamber 14 will be in the fluid containment room 8th that with a membrane 12 from the equalization room 7 is separated, cached.

The friction resistance of the flowing fluid (oil) causes a continuous transmission of force to the frame assembly 9 over the entire distance takes place.

During the return operation, the elastic spring element 10 which between housing part 1.13 and the return damper acts, biased and returns after exceeding the return vertex, the stored energy from the barrel assembly and ensures that this is moved back to the starting position.

In the course of the return process, the projectile has left the barrel and the closure part 2 is unlocked, from this moment comes the barrel assembly to a halt and only the closure housing 17 continues to run backwards, with the spring element 10 which between lock housing 17 and the chamber housing 2.13 acts, is biased, while the cartridge is pulled out and ejected. At the end of the return path of the closure housing 17 are both spring elements 10 biased with almost equal forces which causes the barrel assembly after unlocking the closure member 2 remains in its rear position.

After the closure housing has reached its apex, the prestressed spring element provides 10 for that, the lock housing in the weft direction 110 is moved. During the flow of the closure housing takes the closure part 2 a new cartridge from the magazine and introduces it into the chamber. Because the Federelend 10 which between lock housing and cartridge housing 2.13 the barrel assembly acts, further stretched during the flow, now also the second spring element 10 expand and the barrel assembly is moved forward toward the home position.

During the advance, the piston rod moves 3 from the cylinder room 4 out, with the volume in the cylinder space 4 enlarged and liquid 10 over the control opening 6 from the liquid collecting space 8th , as well as liquid from the decreasing volume of the front cylinder space 16 over the compensation hole 18 in the cylinder room 4 flows.

The timing of the return can hereby by filling the expansion chamber 7 accelerated with strained gas.

After putting on the closure part 2 on the chamber of the barrel 13 the repeating process is complete and the barrel weapon 1 is ready to fire again.
