Claim:
1. A dispensing apparatus for a flowable component, comprising: a storage container having a storage chamber for the reception of the component, a filling opening and a dispensing opening; a piston arranged so as to be displaceable in an expulsion direction within the storage container and being configured to expel the component from the storage chamber via the dispensing opening; an actuation element configured to displace the piston stepwise in a direction of the dispensing opening; and a spring configured to act on the actuation element, the actuation element and the piston being configured and arranged such that, on displacement of the actuation element from a starting position into a final position, the piston is displaced by one step in the direction of the dispensing opening, the actuation element being configured to be displaced by the spring from the final position into the starting position, the actuation element being arranged at the filling opening and the displacement of the actuation element being in the expulsion direction, wherein the piston has a plurality of feed surfaces spaced apart in the expulsion direction, the actuation element has at least one actuation surface, and the feed surfaces and the at least one actuation surface are configured and arranged such that, on the displacement of the actuation element from the starting position into the final position, a force is transmitted in the direction of the dispensing opening onto the piston via the at least one actuation surface and the feed surfaces, wherein the actuation element has an actuation arm oriented in the direction of the dispensing opening and which has the at least one actuation surface, wherein the piston has an inner piston space open in the direction of the filling opening, the inner piston space is bounded transverse to the expulsion direction by a piston jacket, wherein the feed surfaces are formed in the piston jacket, and the actuation arm projects into the inner piston space.
