Abstract
An automatic shut-off nozzle has liquid flow through its vapor return automatically stopped when liquid has filled the vapor line sufficiently in a predetermined period of time to move a float valve to block the vapor return line. This blocking of the vapor return line by the liquid increases the pressure in the tank being filled to cause the automatic shut-off nozzle to stop liquid flow. If the pressure in the tank increases beyond a predetermined pressure when the float valve is in its blocking position, the increased pressure is vented. The automatic shut-off nozzle also stops flow in response to the tank being filled to a predetermined level with liquid or to the pressure in the tank exceeding a predetermined pressure even when there is no blocking of the vapor line by the float valve.
