<p>A device for filling a bottle by means of an annular siphon (3) which is provided with an annular bowl (31), the siphon being accommodated in a feed pipe (2). Provided upstream of the siphon is a pipe (32) which is external to and concentric with the feed pipe and is designed to extend into the annular bowl (31) of the siphon. The diameter of said pipe (32) lies between the external diameter of the siphon and the average diameter of a gas pipe (7). The result of this is that the useful throughflow section of the liquid can be divided by the siphon into a first (33) and a second (34) annular throughflow channel, and the useful throughflow section of the second channel is smaller than that of the first channel, in such a way that the flow in the second channel is virtually laminar in character. In addition, at least one aperture (35) is provided in the intermediate pipe in such a way that the at least one aperture forms a passage between the first and the second channel. <IMAGE></p> |
