The invention relates to a device for administering an injectable product, comprising: a) a casing (3); b) a container for said product accommodated by said casing (3) c) a delivering means (2) for delivering product out of said container (1); d) a drive means (8); and e) a transmission link via which said drive means (8) drives said delivering means (2). The device is characterised in that: f) a fluid space (21, 22) for an incompressible fluid and g) a pressure reducing means (3, 10, 23) are provided in said transmission link; h) wherein said fluid space (21, 22) can be impinged on a drive side by pressure from said drive means (8) and said pressure reducing means (3, 10, 23) reduces a fluid pressure generated by said drive means (8) toward a driven side of said fluid space (21, 22).
