Description

Für hülsenlose, drall- oder flügelstabilisierte Munitionen sind nach den Fig. 5, 6 in einem Gestell 40 einer Maschinenkanone 41 im schwenkbaren Verschlußgehäuse 9.1 ein in Pfeilrichtung A verschiebbarer Patronenkammerblock 42 mit Dichtelementen 43, entsprechend der Munitionen das Drallrohr 4, und das Glattrohr 5, die beiden Druckrohre 21,22, der Zylinder 23, ein längsbeweglicher Steuerschieber 44, eine Zündeinrichtung 45 und eine gestellfeste Magazinwand 46 angeordnet. Weiterhin sind, wie zu der Maschinenkanone 2 für Hülsenmunition beschrieben, eine Schließfeder 30 und in nicht näher gezeigter Weise ein Abzug und eine Puffereinrichtung vorgesehen. Über die Magazinwand 46 sind analog zur F i g. 4 dem Patronenkammerblock 42 sowohl hülsenlose drall- als auch flügelstabilisierte Munitionen 47,48 zuführbar. For caseless, twist or wing stabilized ammunition, see FIGS. 5, 6 in a frame 40 of a machine gun 41 in the pivotable breechblock housing 9.1 a cartridge chamber block 42 with sealing elements which can be displaced in the direction of arrow A 43, according to the ammunition, the twist tube 4 and the smooth tube 5, the two pressure pipes 21,22, the cylinder 23, a longitudinally movable control slide 44, an ignition device 45 and a magazine wall 46 fixed to the frame. Farther are, as described for the automatic cannon 2 for case ammunition, a closing spring 30 and, in a manner not shown, a trigger and a buffer device are provided. About the magazine wall 46 are analogous to FIG. 4 the cartridge chamber block 42 both caseless twist and wing stabilized ammunition 47,48 can be supplied.

Beim Zünden einer hülsenlosen, drallstabilisierten Munition 47 beträgt der durch die Schließfeder 30 getriebene Steuerschieber 44 die Zündeinrichtung 45 (F i g. 5). Das Treibladungsgas treibt dann das Geschoß 35.1 durch das Rohr 4. Nach der Freigabe des Druckrohres 22 durch das Geschoß 35.1 schnellt der Kolben 26 bis zum Anschlag 27 (F i g. 6) und stößt dadurch den Steuerschieber 44 in Pfeilrichtung B in eine nicht dargestellte Fangstellung. Der Steuerschieber 44 bewegt dann den Patronenkammerblock 42 in Pfeilrichtung A in eine Ladestellung. In der gezeichneten Stellung kann eine drallstabilisierte Munition 47 oder durch Verschwenken des Patronenkammerblockes 42 zum Glattrohr 5 hin eine flügelstabilisierte Munition 48 nachgeladen werden. When a caseless, twist-stabilized ammunition is ignited, 47 the control slide 44 driven by the closing spring 30 controls the ignition device 45 (Fig. 5). The propellant gas then drives the projectile 35.1 through the tube 4. After the release of the pressure tube 22 through the projectile 35.1, the piston 26 to snap up to the stop 27 (FIG. 6) and thereby pushes the control slide 44 in the direction of the arrow B in a catch position, not shown. The control slide 44 then moves the Cartridge chamber block 42 in the direction of arrow A in a loading position. In the drawn Position can be a spin-stabilized ammunition 47 or by pivoting the cartridge chamber block 42 a wing-stabilized ammunition 48 can be reloaded towards the smooth barrel 5.

Claims

Claims: 1. Double-barreled automatic cannon with breechblock, breechblock housing and catching device, characterized by the fact that one pipe is a smooth pipe (5) and the other designed as a twist tube (4) and a pivotable closure housing (9, 9.1) is provided for the optional changeover from one pipe to the other.

2. Machine gun according to claim 1, characterized in that in the lock housing (9, 9.1) which can be pivoted by means of pins (10, 11) fixed to the frame Closure (8) for cased ammunition or a cartridge chamber block (4.2) for caseless Ammunition is stored.

3. machine gun with gas drive according to claims 1 and 2, characterized characterized that the pin (10) as in a housing-side, with two pressure pipe mouths (21, 22) provided recess (25) pivotable cylinder (23) is formed, and the cylinder (23) only one corresponding to a pressure tube mouth The invention relates to a double-barreled machine gun with lock, lock housing and catching device.

From US-PS 25 09 734 a double-barreled machine gun is with known two closures for alternating firing from the tubes. Such a one Automatic cannon is usually provided with tubes for spin-stabilized projectiles. It is therefore not possible to use twist or wing stabilized projectiles. because the tubes are only optimally designed for one type of projectile.

The invention is based on the object of a double-barreled machine gun To create wing-stabilized projectiles for firing twist-free or twist-free wing-stabilized projectiles.

The solution to this problem is in the characterizing part of the claim 1 specified. According to the invention, the machine gun can be in a short time from one be converted to a different type of ammunition by only a breechblock housing is pivoted. Due to the closely spaced pipes and only one extraction system the machine gun is compact and can be implemented with relatively few moving parts.

According to claim 2 is a suitable pivot mounting of the lock housing indicated with a closure for cased ammunition or caseless ammunition.

Claim 3 is a special for a machine gun with gas drive simple valve for the gas drive of the closure.

Embodiments according to the invention are shown in the drawing.

It shows F i g. 1 shows a machine gun for case ammunition in cross section F i g. 2 the automatic cannon according to FIG. 1 in section II-II F i g. 3 the automatic cannon corresponding to the section line III-III according to FIG. 2 F i g. 4 shows a cross section through the machine gun according to the section line IV-IV indicated in Figure 2 Fig5 a machine gun for caseless ammunition in cross section F i g. 6 the automatic cannon according to FIG. 5 in section VI-VI.

According to FIG. 1 are in a frame 1, a machine gun 2, a with trains 3 provided twist tube 4, and a smooth tube 5 mounted.

According to FIG. 1, the tubes 4.5 each have a cartridge chamber 6 for Cased ammunition. In the frame 1 there are also two pairs of locking abutments 7 provided for a support flap lock 8 known per se.

This closure 8 is, as can be seen from FIGS. 1, 2, 4, in one Lock housing 9 arranged, which can be pivoted on the frame side via two pins 10, 11 is stored.

The pin 11 is connected to a lever 12 according to FIGS. 2, 4 on which a hydraulic motor 14 controllable via a solenoid valve 13 acts.

Housing-side stops 15, 16 (FIG. 4) limit the respective Pivoting path of the breech block 9.

The frame 1 and the breech housing 9 are used to throw up the case Openings 17,18 are provided.

According to FIG. 1, each tube 4, 5 has a gas extraction hole 19, 20 each having a pressure pipe 21, 22 with the cylinder 23 Pin 10 (F i g. 2,3) of the lock housing 9 is in connection.

This pin 10 can be pivoted in a recess 25 on the frame side stored. The cylinder 23 has a bore 24 which can be opened by pivoting the lock housing 9 each connects a pressure pipe 21, 22 to the cylinder 23. In cylinder 23 is a piston 26 is mounted, which rests against the closure 8 and the piston travel through a housing-side stop 27 is limited.

The shutter 8 has guide rails 28 (F i g. 4), which in corresponding Guides 29 of the lock housing 9 are mounted. At the shutter 8 is a Closing spring 30 on. A buffer block 31 with a buffer spring 32 is at the end of the displacement path of the closure 8 is provided on the frame side. To set the clasp 8 in A latch 33 and a cleat 34 are used in the catching position.

Belted twist or wing stabilized ammunition 35, 36 lie in feed shafts 37 and can optionally be fed to the closure 8 via conveyor wheels 38.

After the spin-stabilized ammunition 35 has been fired (Figs. 1, 2) the gas of the propellant charge drives the closure 8 into the dot-dashed line via the piston 26 Catch position.

To fire a wing-stabilized ammunition 36, the breech 8 via the hydraulic motor 14 around the pins 10, 11 in the one with the core axis 39 pivoted aligned position. The pressure pipe 22 is closed by the cylinder 23 and the connection to the pressure pipe 21 is established. After triggering the trigger 33.34 is in a manner not shown, the wing-stabilized ammunition 36 the The shutter 8 is supplied, which then pushes it into the chamber 6 and locks it.

After the firing has taken place, the from the feed shaft 37 eligible wing stabilized ammunition 36 fired or after pivoting the Closure 8 in the from F i g. 1 or 4 position the twist-stabilized Ammunition 35 are used.
