Definitions
- the invention relates to a mass-locking weapon locking system with a closure part that can be displaceably mounted in a closure housing of a corresponding weapon and an elastic closing element acting on the rear part on the closure part.
- the weapon barrel of the corresponding weapon is closed at the rear by a closure part, wherein the closure member slidably disposed in a nrohr to the weapon axially subsequent closure housing of the weapon and an elastic closing element (Vorholer), in which it usually is an expensive special spring (closing spring), is acted upon (see, for example: Rheinmetall "Weapon Technique Paperback", Dusseldorf, 7th Edition 1985, pages 248 f.).
- Vorholer in which it usually is an expensive special spring (closing spring)
- the invention has for its object to provide a mass-locking locking system, which ensures a high reliability and which is also connected for firing high-performance ammunition with no significant increase in weight of the Vorholers. 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 to use as a prefetcher for the closure part no mechanical closing spring, but a gas spring.
- the closure housing comprises a pneumatic cylinder extending in the direction of the bore axis of the weapon, in which the closure part is displaceably arranged as a sliding piston, the cylinder area extending behind the closure part and filled with a gas forming the closing element acting as a gas spring, i. stores the energy required for the Vorholvorgang.
- a path-dependent adaptation of the characteristic curve of the gas spring can preferably be achieved by arranging at least one throttle opening in the cylinder wall of the pneumatic cylinder, through which part of the rearward and / or backward opening Forward movement of the closure member in the Vorholzylinder compressed gas can escape to the outside.
- a plurality of throttle bores are arranged in the cylinder wall of the pneumatic cylinder and that an annular gap remains between the outer wall of the closure part and the inner wall of the pneumatic cylinder, wherein at least one of the throttle bore is arranged in the cylinder wall in the region of the annular gap.
- the throttle bores may each be provided with an adjusting device such that they are opened or closed depending on the direction of movement of the closure part, the pressure level or the distance traveled by the closure part in a predetermined direction (flow, return).
- the gas for the gas spring may be air.
- FIG. 1 shows the longitudinal section of a schematically represented weapon locking system according to the invention with a closure part arranged in a weapon housing in its starting position;
- FIG 3 shows the closure system shown in Figure 1 during the flow to its starting position.
- FIGS. 1 to 3 denoted by 1 is a mass-locking weapon locking system, which comprises a closure housing 2, which adjoins the rear of the cartridge chamber of a weapon barrel (not shown).
- closure housing 2 In the closure housing 2 is a in the direction of the tube bore axis 100 of the weapon barrel (Fig.1) axially displaceable closure part 3, which also contains the reasons not shown for clarity, required for firing and for removing the cartridge after firing elements.
- closure housing 2 and the closure part 3 form a pneumatic cylinder 4 (pneumatic recuperator), wherein the closure part 3 is designed as a sliding piston and air is used as the gas.
- pneumatic cylinder 4 pneumatic recuperator
- the rear side of the closure part 3 extending, and filled with air cylinder area 5 (storage cylinder) of the pneumatic cylinder 4 forms a closing element acting as a gas spring.
- a plurality of throttle openings 7 are provided in the side wall 6 of the closure housing 2, through which a portion of the compressed air can escape from the closure housing 2 to the outside for pressure relief during the displacement of the closure part 3 ,
- some throttle openings 7 are also arranged in the region of an annular gap 8 between the outer surface 9 of the closure part 3 and the inner surface 10 of the closure housing 2.
- the throttle openings 7 can be opened or closed with the aid of adjustment devices, not shown, depending on the direction of movement of the closure part 3, the pressure level or the path-dependent of the closure part in one direction (flow, return).
- the closure member 3 In the illustrated in Figure 1 starting position of the closure system 1, the closure member 3 is in its forward position and is fixed to a housing stop 11 by a mechanism, not shown. In the storage cylinder 5 is ambient air.
- the air in the storage cylinder 5 is compressed and the pressure in the storage cylinder 5 is increased, so that the closure part 3 is decelerated in its movement in the return direction.
- closure part 3 After the return of the closure part 3 has been completed (FIG. 2), the closure part 3 is again displaced in the weft direction by the pressure force of the compressed air acting on its rear side 13 facing the storage cylinder 5 (FIG. 3) until the closure part 3 returns to its starting position has reached (Fig.).
- the internal pressure of the closure housing 2 may already correspond to the external air pressure before the closure part 3 has reached its starting position. In this case, in the last region of the feed, the internal pressure of the storage cylinder 5 can be reduced below the ambient pressure of the air sink.
- the invention is of course not limited to the specific embodiment shown. Thus, it is not absolutely necessary for the pneumatic cylinder to act on the closure housing itself, but it may also be a separate cylinder arranged in the closure housing and connected thereto, in which the closure part is displaceably arranged as a sliding piston.
