Abstract
A drug delivery device (1) comprises a housing and an expelling assembly adapted to expel a dose of drug from a cartridge (380). The expelling assembly comprises a drive spring (135) which in an energized state is adapted to drive the expelling assembly, a rotating component (550,650) adapted to rotate relative to an axis of rotation during expelling of a dose of drug, and user actuated release means (191, 190) for releasing the drive spring to thereby expel a dose of drug. The device is provided with a brake element (575, 675) being moveable in a plane generally perpendicular to the axis of rotation, the brake element being adapted to engage the rotating component such that during rotation thereof the brake element is moved back and forth, whereby the brake element provides a braking action on the rotating component.
