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. A dose setting means can be provided which comprises a spacer and a movement unit. The spacer moves from a neutral position into an active position such that the driver is stopped by the spacer so 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. The spacer has a through bore in which a spindle with a spindle thread is guided. A pin protrudes into the spindle thread. The spindle thread leads at at least one of its two ends into an annular groove.
