Apparatus for filling bottles with a liquid

Apparatus for filling successive containers of a series of containers with a liquid, comprising a source of liquid;

• container filling means having at least one liquid discharging opening and defining a path for the flow of liquid from said source to said at least one opening;
• and a liquid conveying unit having an inlet in communication with said at least one opening, an outlet for admission of liquid into successive containers, and a liquid swirling channel which conveys liquid from said inlet toward said outlet and extends around said outlet, said outlet having a substantially vertical axis and said channel surrounding said axis, said channel having a liquid-receiving first end in communication with said inlet and and a second end remote rom said first end, said first end being disposed at a predetermined radial distance from said axis and said inlet being spaced apart from said axis a distance which at most equals said predetermined distance, the cross-sectional area of said channel decreasing in the direction of liquid flow from said first end toward said second end at a rate which is proportional to the distance from said first end.
