Abstract

The gas pressure-operated seal at the floor of the projectile prevents slip gases with an absolute seal of the projectile as it passes through the weapon barrel. A deformable sealing disc is provided, pref. of plastic which has high friction strength, heat and cold resistance. A pressure disc is used which is pref. of light metal. A fixture screw with a guide shaft is for central guiding of the sealing disc and the pressure disc which are arranged axially displaceable on the guide shaft. The complete seal with an affixed spring clamp on the projectile floor is connected to the latter within the casing mouth or charge chamber. USE/ADVANTAGE - To provide absolute seal of a projectile as it passes through the weapon barrel.

Description

Bekannte Geschoßabdichtungen in Napfform oder ähnlichem Aufbau haben speziell bei Treibspiegelgeschossen den Nachteil, daß sie beim Mündungsaustritt des Treibspiegelbodens ungleich­ mäßig abreißen oder teilweise lösen. Hierdurch erhält der Treibspiegel eine Unwucht, welche sich nachteilig auf das Unterkalibergeschoß auswirkt und zu Pendlern oder Querschlägern führt.Known bullet seals in cup shape or the like Especially with sabot projectiles, structures have the disadvantage that they are unequal at the mouth of the sabot bottom tear off moderately or partially loosen. This gives the Sabot an unbalance, which adversely affects the Sub-caliber floor impact and commuters or ricochets leads.

Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgleiche Dichtung zu schaffen, welche die oben genannten Nachteile nicht aufweist, eine durch den Gasdruck betätigte Liderung bereits im Patronenhals oder Ladungsraum hat und somit ver­ hindert, daß Schlupfgase mit hoher Geschwindigkeit am Ge­ schoß vorbeifließen können, welche die thermisch hoch belastete Zone des Waffenrohres frühzeitig ausspülen und damit die Rohr­ lebensdauer empfindlich herabsetzen.The invention has for its object a generic Creating seal which has the disadvantages mentioned above does not have an eyelid operated by the gas pressure already in the cartridge neck or cargo space and thus ver prevents slippage gases at high speed on the Ge lap can flow past, which the thermally highly stressed Rinse the area of the gun barrel early and thus the barrel reduce life time sensitively.

Die Erfindung wird nachstehend anhand von einem in der Zeichnung Fig. 1 dargestellten bevorzugten Ausführungsbeispiel näher erläutert.The invention is explained below with reference to a preferred embodiment shown in the drawing Fig. 1.

Gemäß der Zeichnung setzt sich die komplette Dichtung wie folgt, aus einer Befestigungsschraube (1), einer Druckscheibe (2), einer Dichtungsscheibe (3), welche mit der Schraube (1) an dem Treibspiegelboden (4) befestigt sind, wobei die Druckscheibe (2) auf dem Schaft der Schraube (1) axial verschiebbar ist, zusammen. Fig. 2 zeigt die Anbringung der Dichtung an ein Vollkalibergeschoß. Der sich in der Patronenhülse oder Ladungsraum aufbauende Gas­ druck, drückt allseitig mit gleicher Kraft auf die Fläche der Druckscheibe (2). Dadurch wird die Dichtungsscheibe (3) zusammengepreßt und nach außen verdrängt, wobei sie zur abdichtenden Anlage an den Patronenhülsenhals oder die Wan­ dung des Ladungsraumes kommt. Mit dem zunehmenden Gasdruck wird die Dichtungsscheibe (3) beim Austritt aus dem Patronen­ hülsenhals weiter im Durchmesser verformt, so daß übergangs­ los die Gasabdichtung im Waffenrohr erfolgt.According to the drawing, a complete seal is as follows, of a fastening screw (1), a thrust washer (2), a washer (3) which are fixed with the screw (1) on the sabot base (4), said thrust washer ( 2 ) is axially displaceable on the shaft of the screw ( 1 ). Fig. 2 shows the attachment of the seal to a full-caliber floor. The gas pressure building up in the cartridge case or cargo space presses on all sides with the same force on the surface of the pressure disc ( 2 ). As a result, the sealing washer ( 3 ) is pressed together and displaced to the outside, whereby it comes to the sealing abutment on the cartridge case neck or the wall of the cargo space. With increasing gas pressure, the sealing washer ( 3 ) is further deformed in diameter as it emerges from the cartridge, so that the gas seal in the barrel is carried out without transition.

Beim Mündungsaustritt des auf der Zeichnung Fig. 1 darge­ stellten Treibspiegelgeschosses zerlegt sich die Kunststoff­ haube (7) in vier vorgezeichnete Segmente. Die Geschoßauf­ nahme (6) am Treibspiegel (5) zerlegt sich ebenfalls in ihre vorgezeichneten Segmente, womit das Unterkalibergeschoß (8) freigegeben wird und als Fluggeschoß weiterfliegt. Der Treibspiegel (5) mit seiner Dichtung bleibt zurück und fällt zu Boden.At the mouth exit of the sabot projectile shown in the drawing Fig. 1 Darge the plastic hood ( 7 ) breaks down into four pre-drawn segments. The Geschoßauf recording ( 6 ) on the sabot ( 5 ) also breaks down into its pre-drawn segments, whereby the lower-caliber floor ( 8 ) is released and flies on as a flight floor. The sabot ( 5 ) with its seal remains and falls to the ground.

Bei der Verwendung der Dichtung für Vollkalibergeschosse muß die Dichtung mittels Federklemmen (9) Fig. 2 am Geschoß­ boden (4) angebracht werden.When using the seal for full-caliber bullets, the seal must be attached to the floor ( 4 ) using spring clips ( 9 ) Fig. 2.

Wie die Fig. 2 zeigt ist die komplette Dichtung ein Montageteil bestehend aus der Schraube (1), der Druckscheibe (2) und der Dichtungsscheibe (3) welche auf der Scheibe (10) montiert sind, an welcher auch die Federklemmen (9) befestigt sind. As shown in Fig. 2, the complete seal is a mounting part consisting of the screw ( 1 ), the pressure washer ( 2 ) and the sealing washer ( 3 ) which are mounted on the washer ( 10 ), to which the spring clips ( 9 ) are also attached are.
