Abstract
An automatic shut-off nozzle comprises a liquid delivery conduit and a liquid recovery conduit. A valve has a first movable valve portion movable between a valve closed position whereat liquid is precluded from being dispensed from the liquid-dispensing outlet of the liquid delivery conduit and a valve open position whereat liquid is permitted to be dispensed from the liquid-dispensing outlet of the liquid delivery conduit. A manually operable valve control mechanism is reconfigurable between an operating configuration whereat force can be transmitted from the valve control mechanism to the valve to thereby move the first movable valve portion to the valve open position, and a non-operating configuration whereat force cannot be transmitted from the valve control mechanism to the valve. A liquid sensor has a rest state and an actuated state whereat the liquid sensor reconfigures the manually operable valve control mechanism from the operating configuration to the non-operating configuration.
