Definitions
- the invention relates to a sealing ring for the lightening of a propellant charge bearing of an automatic firearm for caseless ammunition against an end face of a firearm element according to the preamble of claim 1.
- a sealing ring is known from DE 10 2005 020 669 A1.
- the sealing ring of DE 10 2005 020 669 A1 represents a classic so-called C-ring seal (named after the C-shaped cross section of the sealing ring).
- C-ring seal named after the C-shaped cross section of the sealing ring.
- two opposing L-shaped profiles are formed (in cross-sectional view), whose legs facing each other form an annular sealing surface.
- a conventional C-ring seal is loosely inserted into the provided for them step-shaped sealing ring seat, that is, there is a certain clearance between the sealing ring and sealing ring seat both in the axial and in the radial direction.
- the C-ring seal may be thrown rearward toward the gun barrel bottom (shutter), whereby the propellant charge chamber can be sealed to the rear.
- the problem with these conventional C-ring seals was that they reacted too slowly in view of the detonative nature of the new propellant charge bodies. Due to the inertia of the C-ring seal, the play between the propellant bottom and the bottom was not closed fast enough.
- the sealing surface of the sealing ring has a first area around the ring opening of the sealing ring and a second area around the first area, the second area being set back from a tangential plane to the first area.
- the second area is convexly shaped, ie bulged or projecting, in relation to the plane-parallel alignment.
- the sealing rings according to the invention can achieve a sustainable, complete suppression of the blow-out.
- the first region of the sealing surface has the shape of a planar annular surface arranged around the annular opening of the sealing ring, and the second region has the shape of a conically shaped surface adjoining the annular surface externally.
- the planar annular surface is preferably set up, to be brought into contact plane-parallel at ambient temperature at the flat end face of the firearm element.
- the cone-shaped surface is preferably set up to be brought into contact with the planar end face of the firearm element in a plane-parallel manner after heating the sealing ring by one or more shots from the firearm.
- the shape of the first region of the sealing surface as a flat annular surface is achieved in an advantageous manner that a good sealing effect of the sealing ring can be achieved even at the beginning of a shot sequence, as long as the sealing ring is still below its elevated operating temperature.
- the raised first region of the sealing surface then sinks downwards or inwards when the sealing ring warms up, the main sealing surface in the second region of the sealing surface comes into contact with the end face of the firearm element.
- the quality of the eyelid depends on the size of the angle between the flat annular surface and the conical shaped surface of the sealing ring.
- This angle is preferably adapted to the deformation behavior of the sealing ring when heated, that the cone-shaped surface after heating of the sealing ring can be brought plane-parallel to the flat end face of the firearm member for conditioning.
- the size of the cone angle of the cone-shaped surface in the cold state of the sealing ring is chosen so that the cone angle is compensated by heating the sealing ring to 0 °, that is, the second region of the sealing surface plane-parallel to the flat end face of the firearm member Plant can be brought.
- the thickness of the circular ring of the flat annular surface of the sealing surface ie the difference between the outer annulus radius and inner annulus radius, in the range of 0.5 mm to 2 mm. Particularly preferably, the thickness is in the range of 0.5 mm to 1 mm.
- the ratio of thickness of Circular ring of the flat annular surface to the length of the generatrix of the truncated cone of the cone-shaped surface is in the range of 1: 6 to 1: 4.
- a particularly good total sealing effect is achieved at a ratio of 1: 5.
- the material from which the sealing ring is made preferably comprises a metal or a metal alloy.
- the use of high temperature steels is advantageous. It is emphasized that, in order to achieve its improved sealing effect, the sealing ring according to the invention does not require flexurally elastic sections and also no elastically prestressed sections. The increased sealing effect is achieved alone by the heating-related deformation of the sealing surface.
- the sealing ring according to the invention is used in a propellant charge bearing for an automatic firearm for caseless ammunition.
- the propellant charge bearing one or more, preferably two, propellant charge chambers have, which are on the closure side and foremostillager noir each provided with a sealing ring.
- such a propellant bearing comprises step-shaped sealing ring seats, in which the sealing rings, which are stepped on the side facing away from the sealing surface, are used to form a labyrinth seal.
- one or more, preferably six, springs are positioned in the sealing ring seats (preferably in recesses) which press the sealing rings against a stop engaging the lateral edge of the sealing rings.
- Propellant body are actively pressed to the shock pad. Further advantageous embodiments and improvements of the invention will become apparent from the following description of preferred implementation examples of the invention. It should be noted that the invention also encompasses further embodiments that result from a combination of features that are listed separately in the patent claims and / or in the description and the figures.

- the lower ring hole edge in turn may preferably be formed bevelled.
- the second region A 2 of the sealing surface has the shape of a outside of the annular surface A, subsequent, cone-shaped surface.
- first region A 1 of the sealing surface has the shape of a flat annular surface, this annular surface lies completely in the tangential plane T described above.
- the planar annular surface A forms, together with the cone-shaped surface A 2, the angle a. This angle a, with which the second

- the insertion device 8 for inserting the projectile 6 into the chamber 3 and the insertion device 9 for inserting the propellant charge 7 into the chamber 5 can be coupled to one another. Through this - preferably rigid - coupling between the two insertion devices 8, 9 can be achieved in a simple manner, a synchronous insertion of the projectile 6 and the propellant 7.
- Figures 7d and 7e show the transition from the first position to a second position, the firing position, as shown in Figures 7f, 7g and Figure 5.
- the firing position In the firing position are the chamber 3 of the projectile bearing 2 and the chamber 5 of
- Propellant charge bearing 4 in alignment with the weapon barrel 1.
- the transition between the first position and the second position is achieved by the preferably opposite rotation of the projectile bearing 2 and the propellant charge bearing 4 about their respective axes of rotation X, Y.
- the insertion devices 8, 9 are preferably not moved or at most retracted a small distance from the maximum insertion position of FIG. 7c in order to ensure undisturbed rotation of the projectile bearing 2 and of the propellant charge bearing 4 to ensure.
