Abstract
An assembly for a medication delivery device includes a body, a piston rod, rotatable with respect to the body, for setting a dose of a medication, and axially movable in a distal direction for delivering the set dose, wherein, in cross-section, the piston rod includes a plurality of ratchet teeth to enable rotation of the piston rod during setting of a dose, and a stop member secured against axial and rotational movement, wherein the stop member mechanically cooperates with the piston rod, wherein, when setting the dose, the piston rod becomes aligned with the stop member, and wherein, when delivering the set dose, the piston rod is moved in the distal direction towards the stop member such that the piston rod and the stop member abut at the end of the dose delivery operation and further distal movement of the piston rod is prevented after dose delivery.
