Abstract

Die vorliegende Erfindung betrifft ein Dosiersystem für eine Injektionsvorrichtung mit einer Zahn-Gewindestange (16) und einer dazu verdrehgesicherten verzahnten Stange (5), welche an einem axialen Abschnitt oder Teil eine Verzahnung (5a) trägt und mit einer Dosierhülse (2), welche mindestens ein Eingriffselement (2a) aufweist, welches in die Verzahnung der verzahnten Stange eingreifen kann, um eine relative Drehbewegung in einer Richtung zu ermöglichen und in Gegenrichtung zu sperren, wobei die verzahnte Stange axial verschiebesicher mit der Dosierhülse gekoppelt ist, wobei mit der Dosierhülse die Größe oder Menge der abzugebenden Substanz durch eine Drehung der Dosierhülse eingestellt wird, wobei die verzahnte Stange relativ zur Dosierhülse bezüglich einer Drehung entgegen der Aufdosier- oder Einstellbewegung verdrehgesichert ist, so dass die verzahnte Stange von der Dosierhülse beim Zurückdrehen mitgenommen oder mitgedreht werden kann und wobei die Zahn-Gewindestange mit der verzahnten Stange verdrehgesichert ist, um die Drehung der Dosierhülse über die verzahnte Stange auf die Zahn-Gewindestange zu übertragen, welche relativ zu der Injektionsvorrichtung axial verschoben wird, um eine dosierte Ausschüttung der Substanz zu verursachen.
