Beschreibung
Zusammenfassung:	A mechanism (11, 12, 14) in the body (4) is used to drive a piston rod (8) and comprises means (14, 17, 25) for guiding the movement of the piston rod relatively to the body while delivering the drug. Further means (15) are provided for releasing the piston rod from the means for guiding the movement, thus enabling a reset of the piston rod to a start position, especially after the receptacle has been emptied and is to be refilled. The device is constructed in such a manner that a reset of the piston rod is facilitated by a stop element (13) inhibiting a reversal of the movement of the piston rod when being reset.
