Patent Claims:	1. A dispensing device for dispensing liquid medium comprising: a housing; an outlet opening for the medium in the housing; a medium reservoir for storage of the medium, the medium reservoir being connected to the housing; a conveying device for transporting the medium from the medium reservoir to the outlet opening; and a flow brake within the housing and in a media duct between the conveying device and the outlet opening; wherein the flow brake has a first flow brake component which can be arranged and fixed relative to the housing or to a second flow brake component during assembly in several differing relative positions, wherein differing flow resistances of the flow brake are achieved depending on a selected one of the relative positions; and wherein the selected one of the relative positions cannot be altered without removing the housing from the medium reservoir. 2. The dispensing device according to claim 1, wherein the first flow brake component is alignable and fixable relative to the second flow brake component or the housing in various rotary settings. 3. The dispensing device according to claim 1, wherein the second flow brake component is fixed to the housing and the first flow brake component is movable during assembly relative to the second flow brake component fixed to the housing. 4. The dispensing device according to claim 1, wherein a relative position of the first flow brake component to the housing or to the second flow brake component is retained non-positively in an assembled state. 5. The dispensing device according to claim 1, wherein a duct section is formed by the first flow brake component and the second flow brake component, wherein a length of the duct section varies depending on awe relative position of the first flow brake component and the second flow brake component. 6. The dispensing device according to claim 1, wherein a first one of the flow brake components has a groove, and the groove is closed at least partially by a second one of the flow brake components. 7. The dispensing device according to claim 6, wherein the groove is, in relation to a main extension direction defined by a dispensing direction, open in the axial direction or open in the radial direction. 8. The dispensing device according to claim 1, wherein first one of the flow brake components is made at least partially from an elastic material. 9. The dispensing device according to claim 1, wherein a passage is formed by the first flow brake component and the second flow brake component, and the first flow brake component and the second flow brake component determine a minimum cross-section of the passage depending on a relative position of the first flow brake component to the second flow brake component. 10. The dispensing device according to claim 1, wherein the flow brake has a plurality of passage openings, and, depending on a relative position of the first flow brake component to the housing or to the second flow brake component, a different one of the passage openings must be passed by the medium during conveying from the medium reservoir to the outlet opening. 11. The dispensing device according to claim 10, wherein the plurality of passage openings are arranged in the second flow brake component or stationarily to the housing, and different passage openings are closed or opened respectively depending on the relative position of the first flow brake component to the housing or to the second flow brake component. 12. The dispensing device according to claim 10, wherein the plurality of passage openings are in the first flow brake component, and, wherein depending on a position of the first flow brake component relative to the housing or relative to the second flow brake component, different passage openings are arranged in a flow path of the medium to the outlet opening. 13. A dispensing device for dispensing liquid medium comprising: a housing; an outlet opening in the housing for allowing the medium to exit the housing; a medium reservoir for storage of the medium, the medium reservoir being connected to the housing, the medium reservoir and the housing forming an interior area within the medium reservoir and the housing and an exterior area outside the medium reservoir and the housing when connected; a conveying device within the housing for transporting the medium from the medium reservoir to the outlet opening; and a flow brake within the housing and interior area and located in a media duct between the conveying device and the outlet opening; wherein the flow brake has a first flow brake component positionable relative to a second flow brake component during assembly in a selected one of several differing relative positions, with differing flow resistances of the flow brake being achieved depending on the selected one of the several differing relative positions; and wherein the first flow brake component cannot be moved relative to the second flow brake component from the exterior area by a user without removing the housing from the medium reservoir. 14. The dispensing device according to claim 13, wherein the second flow brake component includes an annular lower surface having a first opening therein and the first flow brake component includes a cover surface having a second opening therein, the annular lower surface and the cover surface define a duct therebetween, and the cover surface is positioned over the annular lower surface during assembly whereby the differing flow resistances are determined by a distance in the duct between the first opening in the annular lower surface and the second opening in the cover surface. 15. The dispensing device according to claim 14, wherein the second flow brake component includes an inner circular web defining an inner wall of the duct and an outer circular web defining an outer wall of the duct. 16. The dispensing device according to claim 15, wherein the cover surface is located between the inner circular web and the out circular web. 17. The dispensing device according to claim 13, wherein the second flow brake component includes a circular web defining an interior wall of the flow brake, with the circular web being received within the first flow brake component. 18. The dispensing device according to claim 13, wherein the second flow brake component is separate from the housing. 19. The dispensing device according to claim 13, wherein the second flow brake component is within the first flow brake component. 20. The dispensing device according to claim 13, wherein the second flow brake component comprises a plate having a groove ending in an inflow duct and a plurality of holding openings, the first flow brake component comprises a cover having a plurality of holding pins, and the first flow brake component is engaged with the second flow brake component at the selected one of the several differing relative positions by placing the holding pins into the holding openings.
