1. Beverage preparation device (1) provided with a liquid reservoir (2), a dispensing line (4) connected to the reservoir and a pump (14) for displacing liquid from the liquid reservoir (2) to the dispensing line (4), wherein the pump is connected to a control unit (18) and is configured to supply s
1. Beverage preparation device (1) provided with a liquid reservoir (2), a dispensing line (4) connected to the reservoir and a pump (14) for displacing liquid from the liquid reservoir (2) to the dispensing line (4), wherein the pump is connected to a control unit (18) and is configured to supply said liquid to the dispensing line at a first flow rate and at a second flow rate which is greater than the first flow rate, characterized in that the dispensing line comprises an outlet passage (6) with a peripheral wall provided with a plurality of elastically deformable wall sections (7, 21,21′, 26, 29,29′), said peripheral wall surrounds a relatively small dispensing opening at the first flow rate and surrounds a larger dispensing opening at a second flow rate, the peripheral wall forms a closed contour (30) in a cross section of the outlet passage (6), in which the deformable wall sections extend in a longitudinal direction of the outlet passage, wherein the contour (30) is star-shaped, wherein the star-shaped contour has at least three points and the deformable wall sections (21,21′;29,29′) are situated at least at the location of the points as well as between adjacent points, the deformable wall section having dimensions which are such that the discharge speeds of the liquid at the first and the second flow rate differ by not more than 20% or by not more than 10%. 2. Beverage preparation device (1) according to claim 1, wherein the deformable wall sections are elastically deformable. 3. Beverage preparation device (1) according to claim 2, wherein a heating device (3) is incorporated between the liquid reservoir (10) and the dispensing line (4) for heating the liquid to a temperature between 60° C. and 100° C. 4. Beverage preparation device (1) according to claim 3, wherein the outlet passage (6) is oriented substantially vertically and the liquid pressure in the outlet passage is virtually equal to the ambient pressure. 5. Beverage preparation device (1) according to claim 4, wherein the elastic wall section (7,36) is incorporated in a nozzle which is detachably connected to the discharge line. 6. Beverage preparation device (1) according to claim 3, wherein a heating device (3) is incorporated between the liquid reservoir (10) and the dispensing line (4) for heating the liquid to a temperature between 70° C. and 90° C. 7. Beverage preparation device (1) according to claim 1, wherein the deformable wall sections are elastically deformable. 8. Beverage preparation device (1) according to claim 1, wherein a heating device (3) is incorporated between the liquid reservoir (10) and the dispensing line (4) for heating the liquid to a temperature between 60° C. and 100° C. 9. Beverage preparation device (1) according to claim 8, wherein a heating device (3) is incorporated between the liquid reservoir (10) and the dispensing line (4) for heating the liquid to a temperature between 70° C. and 90° C. 10. Beverage preparation device (1) according to claim 1, wherein the outlet passage (6) is oriented substantially vertically and the liquid pressure in the outlet passage is virtually equal to the ambient pressure. 11. Beverage preparation device (1) according to claim 1, wherein the elastic wall section (7,36) is incorporated in a nozzle which is detachably connected to the discharge line. 12. Outlet passage (6) for use in a beverage preparation device (1) according to claim 1.
