ABSTRACT:
A drive and dosing module for an injection device, and an injection device including the module, wherein the module includes a dosing member which can be displaced into one of several dosing positions in relation to a drive member to set a product dose, wherein one of the dosing or drive members forms several dosing stops at axially different heights and rotational stops that are associated with the dosing stops and the other member forms at least one selection element, and wherein the drive member can be moved in relation to the dosing member until it reaches a trigger position in which the at least one selection element attains one of the dosing stops and, in said trigger position, the selection element and the rotational stops combine to lock the rotation of the dosing member in both directions.
