Title
(DE) DICHTUNGSRING UND TREIBLADUNGSLAGER
(EN) SEALING RING AND PROPELLANT CHARGE MAGAZINE
(FR) BAGUE D'ÉTANCHÉITÉ ET MAGASIN DE CHARGE PROPULSIVE
Abstract
(DE) Die Erfindung betrifft einen Dichtungsring (100) zur Liderung eines Treibladungslagers (4) einer automatischen Schusswaffe für hülsenlose Munition insbesondere gegenüber einer Stirnfläche (S) eines Schusswaffenelements, insbesondere eines Verschlusses (77) oder eines Projektillagers (2). Der Dichtungsring (100) weist eine an die Stirnfläche (S) zur Anlage bringbare Dichtungsfläche auf. Diese Dichtungsfläche weist einen ersten Bereich (A1) um die Ringöffnung (D) des Dichtungsrings (100) und einen zweiten Bereich (A2) um den ersten Bereich (A1) auf, wobei der zweite Bereich (A2) gegenüber einer Tangentialfläche (T) an den ersten Bereich (A1) zurückversetzt (α) ist. Die Erfindung betrifft ferner ein Treibladungslager (4) für eine automatische Schusswaffe für hülsenlose Munition, welches zumindest einen der erfindungsgemäßen Dichtungsringe (100) aufweist. Das Treibladungslager (4) weist dabei vorzugsweise ein oder mehrere, insbesondere zwei, Treibladungskammern (5, 50) auf, welche verschlussseitig und projektillagerseitig mit jeweils einem Dichtungsring (100) versehen sind.
(EN) The invention relates to a sealing ring (100) for sealing a propellant charge magazine (4) of an automatic firearm for caseless munition, in particular with respect to an end face (S) of a firearm element, in particular a breech (77) or a projectile magazine (2). The sealing ring (100) comprises a sealing face that can be brought into contact with the end face (S). Said sealing face comprises a first region (A1) around the annular opening (D) of the sealing ring (100) and a second region (A2) around the first region (A1), wherein the second region (A2) is recessed (α) with respect to a tangential surface (T) on the first region (A1). The invention further relates to a propellant charge magazine (4) for an automatic firearm for caseless munition, which has at least one of the sealing rings (100) according to the invention. The propellant charge magazine (4) at the same time comprises one or more, especially two, propellant charge chambers (5, 50), which are provided on the breech side and on the projectile magazine side with a respective sealing ring (100).
(FR) L'invention concerne une bague d'étanchéité (100) destinée à l'obturation d'un magasin de charge propulsive (4) d'une arme à feu automatique pour munition sans douille, en particulier par rapport à une face frontale (S) d'un élément d'arme à feu, en particulier d'une culasse (77) ou d'un magasin de projectiles (2). La bague d'étanchéité (100) comprend une surface d'étanchéité pouvant être amenée en appui sur la face frontale (S). Cette surface d'étanchéité comprend une première zone (A1) autour de l'ouverture annulaire (D) de la bague d'étanchéité (100) et une seconde zone (A2) autour de la première zone (A1), la seconde zone (A2) étant en retrait (α) par rapport à une surface tangentielle (T) s'étendant sur la première zone (A1). L'invention concerne en outre un magasin de charge propulsive (4) pour une arme à feu automatique pour munition sans douille, qui comprend au moins une des bagues d'étanchéité (100) selon l'invention. Le magasin de charge propulsive (4) comprend de préférence une ou plusieurs, en particulier deux, chambres de charge propulsive (5, 50) pourvues, côté culasse et côté magasin de projectiles, d'une bague d'étanchéité (100) respective.
