Definitions
- a drum gun consists essentially of a gun barrel and a drum comprising several chambered cartridges.
- the drum is rotatably mounted about an axis parallel to the tube axis.
- the cartridge is pushed into the cartridge chamber, which is not in line with the tube bore axis.
- Conventional bottle cartridges are pushed in the firing direction in the chamber, while telescope cartridges are introduced into the chamber opposite to the weft direction.
- the drum is rotated or moved until the cartridge and Rohrseelenachse are in line (DE 32 37 728 C2).
- the drum is supported on a plate. Here it comes between drum and gun barrel to Lid ceremoniessproblemen.
- sealing bushes between the drum and gun barrel.
- the sealing bushes were mounted on the drum per cartridge chamber, the sealing bushes being slightly displaced in the weft direction.
- the inner diameter of the sealing bush is slightly larger than the field diameter of the gun barrel.
- the disadvantage is that the seal by means of a socket is often insufficient.
- the problem is to direct the gas jet in time to the end face of the sealing bush, before the sealing bush is acted upon in the radial direction with gas pressure.
- the invention has the object to show a seal between the drum and gun barrel, which seals adequately.
- the invention is based on the idea to incorporate the seal so that it already seals before gas pressure is present. This is done by means of an elastically preloaded seal between the drum and the barrel. In the case that the seal is integrated on the drum side, each cartridge chamber has a seal. For weapons-based integration, a gasket on the weapon barrel is sufficient.
- the profile of the sealing ring between the drum and gun barrel is also L-shaped, wherein the angle between the legs is slightly greater than 90 °.
- This feature causes the lips to be biased and immediately sealed even at lower gas pressures.
- the enhancement of the sealing effect by the gas pressure also ensures a complete seal over the entire pressure range.
- the gas pressure-induced increase in the gap between the drum and the end face of the gun barrel is also absorbed as the radial expansion of the cartridge chamber due to the gas pressure.
- FIG. 1 is a perspective view of a drum gun
- FIG. 2 is a perspective view of the drum gun of FIG. 1 in a sectional view
- Fig. 4 is a detail of the eyelid in section.
- a gun barrel 1 is shown with a drum 2, which has a plurality of cylindrical cartridge chamber 3 for receiving, for example, telescope cartridges (not shown) but also bottle cartridges.
- a Lid mecanicsring 4 is arranged, which preferably have an L-shaped profile (legs 5, 6), wherein the angle between the legs 5 and 6 is slightly greater than 90 ° when the Lid mecanicsring 4 is not biased (Fig 6).
- the drum 2 is rotatably mounted about an axis 7 to the tube axis or slidably to her.
- a disc 8 the Lid ceremoniessringe 4 are biased so far that they are not damaged when turning or moving the drum 2 (alternatively on the barrel 1).
- the support of the drum 2 in the direction Rohrseelenachse is not shown for clarity, but assumed to be known.
- the cartridge is pushed into the cartridge chamber 3 (in a telescope cartridge against the weft direction), which is not in line with the tube soul axis. Subsequently, the drum 2 is moved until the cartridge and tube axis are in line. In this position, the legs 5 and 6 of the Lid mecanicsringes 4, which is also in line, biased and press so against the end face 9 of the gun barrel 1 that is sealed immediately even at low gas pressures. Due to the preferred geometry of the Lid mecanicsringes 4, the gas pressure enhances the sealing effect.
