Abstract
An administering apparatus for delivering a dosage of product including a casing with a reservoir for the product, a conveying device, a dosage setting member mechanically coupled to the conveying device and a stopper for the dosage setting member. The conveying device is formed by a driven device and a drive device. The driven device, a piston rod in one embodiment, is mounted by the casing such that it performs a delivery movement in the form of a delivery stroke in an advancing direction along a translational axis to deliver a product dosage selected using the dosage setting member. The delivery movement of the driven device is effected with the drive device, the drive device and the driven device being coupled. The dosage setting member is coupled to the driven device such that a rotational dosing movement of the dosage setting member and the driven device relative to one another about the translational axis effects a translational dosing movement of the dosage setting member along the translational axis relative to the driven device and the casing. A translational stopper is provided to limit the movement of the dosage setting member. A rotational block is provided which permits the rotational dosing movement in a first rotational direction but blocks the rotational dosing movement in a second rotational direction.
