  • Drive Mechanism for an Injection Device and a Method of Assembling an Injection Device Incorporating Such Drive Mechanism
    Publication number: 20140312074
    Abstract: The present invention relates to a drive mechanism for a spring assisted injection device configured for setting and expelling set doses of a drug. The drive mechanism comprises an assembly provided by a rotatable piston driver (6), a rotatable counter-element (15) and a spring device (19) tensioned between the piston driver (6) and the counter-element (15). During dose setting and during dose expelling the piston driver (6) and the counter-element (15) move relatively along an axis. A releasable interlock (6c, 15d) is provided for maintaining the piston driver (6) and the counter-element (15) in a fixed relative axial condition wherein the spring device (19) is in a tensioned state. The interlock provides for a simplified manufacturing process. The invention also relates to a method of assembling an injection device.
