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.
