The weapon housing 1 is through two outer shells 9, 10 (Fig. 3) sealed against dust and water. This

As a result, there is a bearing bore 1, 1, 15 of the armory 1 or one a mass which is intermittently and relatively difficult to move and is inserted into the weapon housing 1 centered before, the corresponding, influencing the target result. The drive of the roller 3 takes place via one here Causes transverse forces and also a control disk 17 not described in more detail corresponding to 35, which via massive ^ design of the weapon housing requires a pin 18 also in the weapon housing 1

For this purpose, a slide switch is to be operated manually, the drive of the control disk 17 can be used in a known manner

in turn, the cartridge chamber swivels laterally out of the way either by means of a gas pressure drive or core axis and the ejector pin is actuated by an externally driven motor,

to create low lateral forces. The roller 3 has on the closure side a circular arc

The advantage of this is the narrow and a small shaped bead 3.4 (Fig. 1, la). Corresponding to the outer circumference having cartridge chamber housing, 50 radius of this bead 3.4 is in the weapon housing 1, which can be brought with little effort from the firing position in the area of a loading opening 1.2 or in one of the loading position and vice versa. Forces lying transversely to the pivoting area of the bead 3.4 corresponding core axis occur in the case of the roller near the area a recess 1.3 is provided.

In addition, an eccentricity £, to the axis of the soul chamber C , which is smaller than the angular or parallel arrangement of one of the radius D, but slightly larger than the radius F of the magazine channel, the loading position of the roller can be reduced slightly to the closure-side end face 4.1 of a cartridge 21 Angular distance lie so that a rapid reload is 60.

is present. The eccentricity E can minimally correspond to the radius F.

In the loading position of the roller can correspond to save time. If E <F , when a slide provided with appropriate plungers is pivoted into the core axis Cam, the cartridge hits both the case ejection or, in the case of caseless 22, and thus leads to a load jam.
Ammunition, the ejection of failures as well as the 65 The cartridge chamber 4 is done in two sections 4.2,4.3 cartridge feed, whereby this weapon (Fig. La) is divided, with section 4.2 a caseless propellant charge 23 with attached ammunition for both caseless and caseless ammunition Is consumable. gasket 24, while section 4.3 for a,

with the propellant charge 23 connected projectile 25, has a bore 26 This bore 26 is opposite the weapon barrel 5 and the weapon housing 1 are sealed by a liner 27. The firing pin 6 is in one Bore 22.1 of the closure piece 22 out.

As shown in FIG. 2 shows the cartridge pusher or ejector 8 two coaxial to the cartridge chamber axis C lying plungers 8.1, 8.2, which are reciprocally movable to the cartridge chamber 4. This cartridge slide 8 is also controlled by the control disc 17 or control cam 17.2 (Fig. 3) controllable. For this purpose, the cartridge slide 8 has one of the FIGS. 1 and 3 evident pin 83. the During a stroke, plungers 8.1, 8.2 slide in a bore 1.4 of the weapon housing 1 or 9.1 of the shells

The firing pin 6 is driven by the pivotably mounted hammer 7, which can be driven by the control disk 17 and via a pin 7.1 (FIG. 1) or a lever (not shown).

On the underside of the weapon housing 1 is arranged in the soul axis direction, through the shells 9, 10 limited magazine channel 28 (FIGS. 1, 3) with a rectangular cross section is provided.

From Figure 4 shows a roller 3.6, whose Cartridge chamber 4 has lids 27, 27.1 on both sides. This design is suitable for caseless Ammunition.

One from FIG. The roller 3.7 shown in FIG. 5 has three cartridge chambers 4. These are arranged in one plane and are intended for a wa ^f fe with three tubes. The eccentricity E corresponds to that from FIG. 1 a resulting eccentricity.

The insertion of a cartridge 21 arranged in the magazine channel 28 or in a loading strip 29 with Consumption seal 24 in the roller 3 (FIG. 2) takes place through the plunger 8.1 of the cartridge inserter 8. Then the roller 3 pivots through 90 ° with the cartridge 21 in the core axis Cein and is there through the plunger 8.2 and set by the locking hole 3.5. The hammer 7 then accelerates the firing pin 6. which ignites the cartridge 21 so that the projectile 25 drives through the weapon barrel 5. The functional sequences described are effected by the control disk 17.

These functions are also present in a weapon with the roller 3.7 described in relation to FIG. 5. whereby three projectiles fired at the same time or in cycles will.
