Abstract: A device for administering a fluid can include a cylinder, a piston connected to a piston rod, and a tensioning device connected to the piston rod. The tensioning device includes a ramp which is rotatable via a motor, a ramp track, and a roller which is in contact with the ramp track and which is mounted rotatably in a driver. A dose setting means can be provided which comprises a spacer and a movement unit. The movement unit can move the spacer from a neutral position into an active position between the driver and the cylinder such that the driver is stopped by the spacer and therefore the piston stroke during the movement of the piston to the open dispensing end is shorter in comparison to the case in which the spacer is in its neutral position.

Abstract: A device for administering a fluid can include a cylinder, a piston connected to a piston rod, and a tensioning device connected to the piston rod. In a dispensing procedure, a ramp track is rotated until a roller runs over a transfer region and is accelerated toward the first plateau and, as a result, the piston is moved toward an open dispensing end. The ramp track runs on the face side of a wall extending along a circular path. A cover engages over the ramp track, the driver and the roller and has at least one scraper extending counter to the first direction and extending within the wall as far as the inner side of the wall, and thus scrapes off lubricant located on the inner side from the inner side.

Abstract: A magazine for accommodating pellets for use in an injector includes a barrel comprising a hollow cylindrical compartment with an open front end and an open rear end. The cross-section of the compartment is selected to accommodate a pellet. The cross section of the rear end is smaller than the accommodated pellet so that it cannot be extracted from the rear end of the compartment. The magazine further includes a cover for closing the front end, including a dispensing opening which, in the closed state, is positioned in front of the front end and has a cross-section selected such that the pellet can pass through the dispensing opening. At least one bar projecting into the dispensing opening prevents the pellet from accidentally falling out, and when subjected to a predetermined force, can be bent outwards such that the pellet can be delivered through the dispensing opening.
