Abstract

The hydraulically controlled breech for an automatic weapon has a chamber inside which travels a piston with a large section at the cartridge carrying end and a smaller intermediate piston. These pistons control the displacement of liquid from one end of the chamber to the other. At a position about half-way along the chamber, is a partition through which the smaller piston can travel. After this piston has passed through the hole in the middle of the partition, the liquid can then pass through the hole. A larger displacement of liquid is then controlled by the larger piston.

Description

Titel: Hydraulischer Verschluß für automatische WaffenTitle: Hydraulic breech for automatic weapons

Lösung: Das Verschlußstück besteht aus einem Doppelkolben in Tandemanordnnng,der sich in einem Zylinder befindet, der mit Flüssigkeit gefüllt ist.Solution: The closure piece consists of a double piston in tandem arrangement, the located in a cylinder filled with liquid.

Der vordere Kolben nimmt das Patronenlager auf. The front piston receives the chamber.

Der hintere Kolben ist im Querschnitt etwas kleiner als der vordere Kolben und befindet sich in der Ausgangsstellung in einer Querschnittsverengung des Zylinders (Blende),wobei er entweder eine Bohrung besitzt oder einen Ringspalt freiläßt. The rear piston is slightly smaller in cross section than the front one Piston and is in the starting position in a cross-sectional constriction of the cylinder (orifice), with either a bore or an annular gap releases.

Der Zylider wird entweder mit einem durch eine Feder abgestützten Kolben,oder mit einem durch eine Membran von der Flüssigkeit abgetrenntem Gaspolster abgeschlossen. The cylinder is either supported by a spring Piston, or with a gas cushion separated from the liquid by a membrane closed.

Beschreibung der Funktionsweise eines Ausführungsbeispiels: (Siehe Zeichnung) Der Rückstoß der gezündeten Patrone wirkt auf den größeren Kolben und versucht ihn zurückzutreiben.Description of the functionality of an exemplary embodiment: (See Drawing) The recoil of the ignited cartridge acts on the larger piston and tries to drive him back.

Die dabei entstehende Rückwärtsbewegung des Kolbens verursacht eine bestimmte Verdrängung der Flüssigkeit.Der sich gleichzeitig, weil starr verbunden,um denselben eg sich bewegende kleinere Kolben verdrängt durch die Bewegung in der Blende ebenfalls Flüssigkeit.The resulting backward movement of the piston causes a certain displacement of the liquid. The simultaneous, because rigidly connected to the same eg moving smaller piston displaced by the movement in the Blend liquid as well.

Aber nicht in gleichem ausmaß.But not to the same extent.

Die entstehende Volumendifferenz wird durch die enge Bohrung oder den Ringspalt des kleineren Kolbens in den sich dahinter befindlichen Zylinderabschnitt ausgeglichen.Dazu ist ein relativ hoher und durch das Maß der Bohrung (Ringspalt) mühelos variierbarer Druck notwendig.The resulting volume difference is due to the narrow bore or the annular gap of the smaller piston into the cylinder section behind it In addition, a relatively high and due to the size of the bore (annular gap) effortlessly variable pressure necessary.

Nach Passieren der Blende durch den kleineren Kolben strömt die Flüssigkeit relativ ungehindert durch die Blende.After passing the orifice through the smaller piston, the liquid flows relatively unhindered by the aperture.

Der Verschluß ist geöffnet.The shutter is open.

Durch die Wirkung der Feder oder des Gaspolsterdruckes läuft der Vorgang sinngemäß in umgekehrter Reihenfolge ab.The process runs through the action of the spring or the pressure of the gas cushion analogously in reverse order.

Patentansprüche Oberbegriff: U Hydraulischer Verschluß für automatische Waffen Kennz.Teil: {- dadurch gekennzeichnet,daß in einem Zylinder, der durch eine Querschnittsverengung (Blende) in zwei Abschnitte unterteilt ist,durch die Bewegung zweier starr miteinander verbundenen Kolben mit verschiedenem Querschnitt in einem Zylinderabschnitt eine Volumenverkleinerung entsteht,weil der Kolben mit dem größeren Querschnitt mehr Volumen verdrngt,als der Kolben mit dem kleineren Querschnitt während der Bewegung in der Blende freigibt. Claims preamble: U Hydraulic lock for automatic Weapons Kennz.Teil: {- characterized in that in a cylinder, which is through a Cross-sectional constriction (aperture) is divided into two sections, due to the movement two rigidly interconnected pistons with different cross-sections in one Cylinder section a reduction in volume occurs because the piston with the larger one Cross section displaces more volume than the piston with the smaller cross section during which releases movement in the diaphragm. Weiterhin dadurch gekennzeichnet,daß die,sich in diesem Zylinderabschnitt befindliche Flüssigkeit,durch diese Bewegung durch eine enge Bohrung oder einen Ringspalt in den verbleibenden Zylinderabschnitt gepreßt wird. Further characterized in that the, located in this cylinder section liquid, through this movement through a narrow bore or a Annular gap is pressed into the remaining cylinder section. Weiterhin dadurch gekennzeichnet,daß,nachdem der kleinere Kolben die Blende passiert hat, die Flüssigkeit durch die nun freigegebene Blende strömt. Further characterized in that after the smaller piston has passed the aperture, the liquid flows through the aperture that has now been released.
