Device for administering a fluid

A device for administering a fluid is provided, with The tensioning device (S) has a ramp () which is rotatable by means of a motor () and has a ramp track () extending along a helical line, wherein the ramp track () ascends from a first plateau along a region of inclination (S, S) to a second plateau and descends from the second plateau to the first plateau via a transition flank (). The tensioning device (S) furthermore has a roller () which is in contact with the ramp track () and is mounted rotatably in a driver (), which is connected to that end of the piston rod () which protrudes out of the cylinder (), and therefore, upon rotation of the ramp (), the ramp track () runs below the roller (), which thereby rotates, wherein the roller () has a support region () which rests on the region of inclination (S, S) of the ramp track (), and at least one laterally adjoining side region () which has a smaller outside diameter than the support region () and which does not rest on the region of inclination (S, S) of the ramp track (), wherein, during rotation of the ramp, both the support region () and the side region () come into contact with an edge () of the ramp track (), said edge connecting the second plateau to the transition flank ().

A device for administering a fluid is provided, with a cylinder, a piston, a piston rod, a receiving block (10), a nonreturn valve, a tensioning device, a ramp, a motor (12) a ramp track, a roller and a driver (50).
