摘要： A fluid dispensing nozzle incorporating an automatic shutoff mechanism responsive to the filling of a receiving tank to a level near its top is provided with mechanical means operable independently of the automatic shutoff mechanism to open a flow passage through the nozzle to permit the complete filling of a receiving tank after the shutoff mechanism has been actuated. The shutoff mechanism includes a movable, pressure-sensitive member which is displaced by a pressure differential created thereon in response to the substantial filling of a receiving tank to pivot a latch out of restraining engagement with a roller on a slide rod normally serving to hold a valve in the nozzle open. The releasing of the latch from the roller causes the slide rod to be shifted by valve spring pressure to close the nozzle valve.
