ABSTRACT:
A fuel dispensing nozzle (10) has a body (12) in which a fuel passage is formed. A spout assembly (18) is attachable to the body in fluid communication therewith for fuel to flow from the body through the spout and into a tank (T). A valve (20) is interposed in the passage and controls fuel flow through the body. A flexible bellows (80) fits over the spout with the outer end (72) thereof sealingly engaging an inlet (I) of the tank to prevent fuel vapors from escaping into the atmosphere. A control apparatus is responsive to movement of the bellows when the spout is inserted into the tank to open the valve, and to removal of the spout from the tank to close the valve. An apparatus (176) is responsive to the vapor pressure within the tank to effect closing of the valve when an overpressure condition occurs thereby to prevent vapor from escaping into the atmosphere. The apparatus includes first and second pivotally connected levers (132, 136) one of which moves in response to movement of the bellows and the other of which moves in response to the vapor pressure reaching a predetermined level indicative of the tank being substantially full to close the valve and prevent vapors from escaping.
