1. An apparatus for mixing water and a beverage concentrate, said apparatus comprising: a first passage channel comprising an entry region, a central section and an exit region, said central section having a smaller passage cross-section than said entry region and said exit region, said first passage channel passing through a housing from an inlet to an outlet and said central section being made short as compared to said entry region and said exit region; a second passage channel ending downstream in the smaller passage cross-section of said first passage channel, wherein the water flows in said first passage channel and the beverage concentrate flows in said second passage channel; at least one bypass channel extending from said entry region of said first passage channel to said exit region; and a means for setting the passing amount of at least one of the water and the beverage concentrate. 2. The apparatus as defined in claim 1, wherein in said entry region (9), a relief chamber (14) is formed. 3. The apparatus as defined in claim 1, wherein said exit region (11), at least in the area of its free end, comprises an increasingly widening cross-section. 4. The apparatus as defined in claim 1, wherein said second passage channel (6) ends essentially perpendicularly,to said first passage channel. 5. The apparatus as defined in claim 1, wherein the bypass channel comprises an essentially constant cross-section. 6. The apparatus as defined in claim 5, wherein the bypass channel (15) extends in parallel to said central section (10) of said first passage channel (3). 7. The apparatus as defined in claim 1, wherein said bypass channel with its upstream end ends in a relief chamber and with its downstream end ends into said exit region of said first passage channel with a distance to a junction of said second passage channel. 8. The apparatus as defined in claim 7, wherein a junction of said bypass channel into said exit region of said first passage channel is formed by one piercing bore respectively, each extending with a sharp angle to the axis of said first passage channel. 9. The apparatus as defined in claim 8, wherein said junction of said bypass channel includes junction openings which have a cross-section narrowing like a nozzle. 10. The apparatus as defined in claim 9, wherein said means for setting the passing amount of at least one of the water or the beverage concentrate comprises dosing means which are insertable into the junction openings. 11. The apparatus as defined in claim 10, wherein said dosing means are formed by pins which are guided in cross bores and which are adjustable by means of a fine thread. 12. The apparatus as defined in claim 10, characterized in that said second passage channel (6) essentially perpendicularly ends in said first passage channel (3) downstream of said smaller passage cross-section (10) through said cross bore (20) of said dosing means. 13. The apparatus as defined in claim 11, wherein said second passage channel essentially perpendicularly ends in said first passage channel downstream of said smaller passage cross-section through said cross bore of said dosing means. 14. The apparatus as defined in claim 1, wherein said housing (2) is made of plastic material. 15. The apparatus as defined in claim 1, wherein said housing (2) is built as one-piece injection-molded body. 16. The apparatus as defined in claim 1, wherein said housing (2) comprises a means for fixing said housing (23). 17. The apparatus as defined in claim 1, wherein said housing (2) comprises connecting necks (21) for connection of connecting hoses, concentrate reservoirs, and liquid supply lines. 18. The apparatus as defined in claim 1, characterized in that the bypass channel (15) extends from said entry region (9) of said first passage channel (3) to said exit region (11), it therein showing an essentially constant cross-section.
