Abstract
An autoinjector including a housing; an axially fixed product container; a torsion spring; a drive element; a propulsion element; and a needle protection sleeve is configured such that when the autoinjector is pressed against an injection location, the needle protection sleeve undergoes an actuation movement in the proximal direction. For discharging liquid from the product container through an injection needle into the injection location, the torsion spring sets the drive element into rotation and the rotating drive element causes a movement of the propulsion element and a piston in the product container in the distal direction. The autoinjector includes a coupling which, due to the actuation movement of the needle protection sleeve, releases the drive element for rotation, where the coupling is between a first and second coupling element in an engagement of locking surfaces, and can be disengaged by an axial coupling stroke of the two coupling elements.
