The tap is directly connected to the dispensing outlet by providing a connecting coupling which connects the air supply conduit to the beverage dispensing conduit, the beverage dispensing conduit comprising a Venturi segment between the tap and the outlet in which, by flowing through the Venturi segment, the fluid passage reduces the cross section thereof and then increases the cross section thereof as in a Venturi conduit. An air passage regulating valve is provided in said air supply conduit for regulating the width of the air passage.
