Flow control device

Abstract

A flow control device for use in a supply line between a pressurized liquid container and a dispenser for the liquid, the flow control device comprising a chamber (200) having an inlet (114) for receiving liquid from the container; a base section (102) comprising a chamber outlet (122) for supplying liquid to the dispenser; a vent valve (110) for venting gas from the chamber (200); a float valve (106) comprising a float section (142) and a seat section (146) and movable to and from an open position wherein the chamber outlet (122) is open to liquid flow and a closed position wherein the chamber outlet (122) is closed to liquid flow; and a float valve opening mechanism (120) Wherein the float section (142) of the float valve (106) comprises a plurality of protrusions (143), at least some of which engage the inside (138) of the chamber (200) so as to locate the float valve (106) substantially in line with the chamber outlet (122). In this way, the float valve can guide itself into the correct position without the need for additional guiding components.
