Beschreibung
Zusammenfassung:	A device for injection comprising a housing, a cylindrical driving mechanism, and a ratchet mechanism, said ratchet mechanism comprising a gear with asymmetrical teeth that have a sloping surface and a stop surface, the gear being mounted on the cylindrical driving mechanism, a pawl, a spring which presses the pawl against the gear, and a cylindrical carrier element, wherein the pawl is mounted for radial movement inside the cylindrical carrier element, which is mounted inside the housing and is rigidly connected thereto. The technical effect of the present invention is to provide highly reliable locking of the cylindrical driving mechanism against reverse rotation, while at the same time producing an accompanying sound during forward rotation. The device is simple to manufacture and the ratchet mechanism is accommodated inside the housing.
