Abstract

A flow control device for locating in a vessel to control the level of a liquid comprises a housing 1 defining a primary chamber 5, and a liquid supply aperture 11 at an upper portion. A float 15 is located within the primary chamber 5 and has a through bore 16 therein for flow of liquid. A fluid conduit 13 communicates between the liquid supply aperture 11 and the through bore 16 in the float 15. The fluid conduit 13 comprises a flexible tube which in an extended state has a substantially open through bore when the float 15 is in the down position, and assumes a kinked state with a substantially occluded through bore when the float 15 is in the up position.
