DETAILED DESCRIPTION
[0028] FIG. 1 shows a partial view of a first embodiment variant of a dispensing device 1 in a sectional representation. Only a spray fitting of dispensing device 1, by means of which a carbonated liquid and mixed water can be filled into a container (not shown here), such as, for example, a glass or a bottle, is shown in FIG. 1. A fitting housing 2 of dispensing device 1 is connected to a hose 24 which comprises a first tube line 25 and a second tube line 26 extending through first tube line 25. A first channel 27 with an annular cross-sectional area for the mixed water and a second channel 28 for the carbonated liquid are thus formed in hose 24. First channel 27 connects a mixed water source (not shown here), for example, a mixed water outlet of a mixing valve or thermostatic mixing valve, of dispensing device 1 to a connection adapter 29. Second channel 28 connects a carbonated liquid source (not shown here), such as, for example, a carbonator vessel, of dispensing device 1 to connection adapter 29. Connection adapter 29 connects first channel 27 to a first conduit 3 in fitting housing 2 and second channel 28 to a second conduit 23 in fitting housing 2. The carbonated liquid can be guided from connection adapter 29 to an outlet opening 7 via first conduit 3. In addition, the mixed water can be guided through second conduit 23 from connection adapter 29 to a further outlet opening (not shown here) for the mixed water. In first conduit 3, a nozzle insert 4 is disposed in a receiving space 20. Nozzle insert 4 has a guide channel 5 with a first diameter 13. First diameter 13 is greater than a third diameter 14 of first conduit 3. An expansion space 19 with a second diameter 22 is formed between nozzle insert 4 and outlet opening 7. Second diameter 22 of expansion space 19 is greater than first diameter 13 and second diameter 14.
[0029] FIG. 2 shows nozzle insert 4 in a perspective representation. Nozzle insert 4 extends along a longitudinal axis 8 and has a circumferential collar 33 at a first longitudinal end 30 and a baffle wall 6 at a second longitudinal end 31. Baffle wall 6 runs orthogonal to longitudinal axis 8 of nozzle insert 4. Furthermore, baffle wall 6 is connected via a first web 9 and a second web 10 to nozzle insert 4, wherein first web 9 and second web 10 extend parallel to longitudinal axis 8. First web 9 and second web 10 are also arranged offset to another by 180 about longitudinal axis 8. A radial first outlet opening 11 and a radial second outlet opening 12 are formed between first web 9 and second web 10 in a circumferential direction of nozzle insert 4. In addition, nozzle insert 4 has a circumferential surface 16 with a circumferential groove 17 into which a seal 18, shown in FIG. 1, can be placed in the manner of an O-ring.
[0030] FIG. 3 shows the nozzle insert 4 in a sectional representation. Nozzle insert 4 has at first longitudinal end 30 an inlet cone, which opens into guide channel 5. Guide channel 5 extends from first longitudinal end 30 parallel and coaxially with longitudinal axis 8 in the direction of baffle wall 6.
[0031] FIG. 4 shows a partial view of a second embodiment variant of a dispensing device 1 in which only a pull-out rinsing spray of dispensing device 1 is shown. The rinsing spray of dispensing device 1 has a fitting housing 2 to which a carbonated liquid and mixed water can be supplied by means of a hose 24. Hose 24 is formed identical to the hose 24 shown in FIG. 1.
[0032] It is evident from the sectional representation of dispensing device 1 in FIG. 5 that a first channel 27 for the carbonated water of hose 24 opens into a guide channel 5 of a nozzle insert 4. Nozzle insert 4 is formed identical to nozzle insert 4 shown in FIGS. 2 and 3. Furthermore, mixed water can be conducted by a second channel 28 of hose 24. The mixed water is passed through a second conduit 23 around nozzle insert 4 to an outlet opening 7.
[0033] FIG. 6 shows an enlarged representation of the sectional representation of dispensing device 1 shown in FIG. 5. The carbonated water flows through guide channel 5 of nozzle insert 4 and hits baffle wall 6. As a result, the carbonated water is vortexed and exits via a first outlet opening 11 and a second outlet opening 12 out of nozzle insert 4 and enters into an expansion space 19. From there, the carbonated water flows through a mousseur 32 and exits out of outlet opening 7 shown in FIG. 5. In the embodiment variant shown here, nozzle insert 4 is held with an adapter 21 in fitting housing 2. For this purpose, a receiving space 20 for nozzle insert 4 is formed in adapter 21.
[0034] Carbonated water with a high CO2 concentration and with an attractive flow pattern can be dispensed by the present invention.
[0035] The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are to be included within the scope of the following claims.
