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.
