<p>AUTOMATIC SHUT-OFF NOZZLE HAVING AN ARRANGEMENT FOR CONTROLLING WHEN AUTOMATIC SHUT OFF OCCURS IN RESPONSE TO PRESSURE IN A SEALED TANK 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.</p> |
