Abstract
An automatic shut-off nozzle has a diaphragm responsive to the vapor pressure in a sealed tank to stop the liquid flow through the nozzle when a predetermined pressure exists in the sealed tank. The force of a spring, which acts on the side of the diaphragm not exposed to the vapor pressure in the tank, is adjusted to insure that the flow is stopped at the predetermined pressure.
