Abstract
An automatic shut-off nozzle has a first diaphragm responsive to the liquid in the tank being filled reaching a predetermined level to automatically stop flow through the nozzle. Flow also is automatically stopped when a second diaphragm responds to inactivation of a pump supplying the liquid to the nozzle. When a venturi poppet valve is located downstream from a main poppet valve in the nozzle, the venturi poppet valve has a bleed passage extending therethrough to enable the pressure upstream thereof and acting on the second diaphragm to be reduced to zero the pump is inactivated.
