Title
(DE) AUSDRÜCKVORRICHTUNG FÜR EINE KARTUSCHE
(EN) EJECTION DEVICE FOR A CARTRIDGE
(FR) DISPOSITIF D'EJECTION POUR UNE CARTOUCHE
Abstract
(DE)
Eine Ausdrückvorrichtung für eine Kartusche, die zwei konzentrisch zueinander angeordnete Kammern (1, 2) und einen Kolben (4, 5) für jede Kammer (1, 2) aufweist, weist Ausdrückstössel auf, die in Richtung der Kartuschenaustrittsöffnung (3) verschiebbar sind. Es ist eine mit der Kartusche axial verriegelbare Kappe (6) vorgesehen, durch welche die Ausdrückstössel geführt sind. Die Ausdrückstössel für den Ringkolben (5) sind an ihren äusseren Enden über ein Kopfstück (11) miteinander verbunden. Am Kopfstück (11) stützt sich eine Gewindespindel (9) ab, die durch eine Gewindebohrung (8) der Kappe (6) verläuft und die als Ausdrückstössel für den mittleren Kolben (4) dient.
(EN)
The invention relates to an ejection device for a cartridge which comprises two chambers (1, 2) arranged concentrically to one another. Each chamber (1, 2) is provided with a piston (4, 5). The ejection device also comprises ejection tappets which can be shifted in the direction of the outlet (3) of the cartridge. A cap (6) is provided which can be axially locked with the cartridge. The ejection tappets are guided through said cap (6). The external ends of the ejection tappets for the annular piston (5) are connected to one another via a top piece (11). A threaded spindle (9) is supported at the top piece (11). Said threaded spindle (9) extends through a threaded borehole (8) of the cap (6) and serves as an ejection tappet for the middle piston (4).
(FR)
L'invention concerne un dispositif d'éjection pour une cartouche présentant deux chambres (1, 2), placées de manière concentrique l'une par rapport à l'autre, et un piston (4, 5) pour chaque chambre (1, 2). Ce dispositif d'éjection présente des poussoirs d'éjection qui peuvent coulisser en direction de l'ouverture de cartouche (3). Ces poussoirs d'éjection sont guidés à travers un capuchon (6) pouvant être bloqué dans le sens axial avec la cartouche. Les poussoirs d'éjection pour le piston annulaire (5) sont raccordés entre eux au niveau de leurs extrémités extérieures par l'intermédiaire d'un élément de tête (11) sur lequel prend appui une broche filetée (9) s'étendant à travers un orifice fileté (8) du capuchon (6) et servant de poussoir d'éjection pour le piston central (4).
