Abstract
An auto-injector for administering a dose of a liquid medicament includes an elongate tubular case and a carrier subassembly including a tubular carrier slidably arranged inside the case. The carrier is adapted to contain a syringe with a hollow injection needle, a drive spring, and a plunger for forwarding load of the drive spring to a stopper of the syringe, wherein the syringe is lockable for joint axial translation with the carrier, wherein the drive spring acts between the carrier and the plunger, wherein the plunger, in an initial state, is locked to the carrier by a ramped engagement to the carrier and by being prevented from rotating out of this ramped engagement, depending on a relative longitudinal position of the carrier in the case, and wherein the plunger is arranged to be released for rotating out of the ramped engagement.
