A compact, self-contained, automatic flow control and venting apparatus for the automatic interruption of liquid flowing into a liquid storage receptacle during the refilling process is disclosed wherein a dual-chambered, offset valve mechanism is controlled by the movement of a float assembly. A bi-directional lever member linked to the float assembly is used to control the movement of the valve mechanism between its open and closed positions. The apparatus also provides for the automatic release of air or vapor from within the receptacle during the refilling process and for the automatic checking of liquid backflow through the valve mechanism.
