Title (EN) DRIVE APPARATUS FOR INJECTION DEVICES
(FR) DISPOSITIF D'ENTRAÎNEMENT POUR APPAREILS D'INJECTION
(DE) ANTRIEBSVORRICHTUNG FÜR INJEKTIONSGERÄTE
Abstract:
(EN) The invention relates to an injection device having reduced space requirements and having a reliable drive. Because of a plunger rod having a maximum outside diameter that is considerably less than the diameter of the product container, the plunger rod is not longitudinally guided by the product container. This is compensated by a centering aid on the plunger rod tip in the form of a centering flange or a centering stub, which centering aid counteracts inaccurate or insufficient alignment of the plunger rod in the product container.
(FR) L'invention concerne un appareil d'injection d'un encombrement réduit et doté d'un entraînement fiable. Grâce à une tige de piston d'un diamètre externe maximal nettement inférieur au diamètre du contenant de produit, tout guidage longitudinal de la tige de piston dans le contenant de produit devient superflu. Cela est compensé par un auxiliaire de centrage sur l'extrémité de la tige de piston sous la forme d'un rebord de centrage ou d'un élément tronconique de centrage qui agit à l'encontre d'une orientation imprécise ou insuffisante de la tige de piston dans le contenant de produit.
(DE) Die Erfindung betrifft ein Injektionsgerät mit einem reduzierten Platzbedarf und einem sicheren Antrieb. Durch eine Kolbenstange mit einem Maximalaussendurchmesser, welcher deutlich kleiner ist als der Durchmesser des Produktbehälters, entfällt eine Längsführung der Kolbenstange durch den Produktbehälter. Dies wird kompensiert durch eine Zentrierhilfe an der Kolbenstangenspitze in Form eines Zentrierflansches oder eines Zentrierstumpfs, welche einer ungenauen oder unzureichenden Ausrichtung der Kolbenstange im Produktbehälter entgegenwirkt.
