ABSTRACT:
A valve means for a fuel dispensing nozzle located in the nozzle discharge spout at the outlet end thereof for sealing the outlet end to prevent the flow of fuel and fuel vapors out of the discharge spout when the nozzle vapor-seal valve is closed. The valve means is responsive to the operation of the vapor-seal valve so that when the vapor-seal valve is closed when the nozzle is not in use, the valve means is closed and so that when the vapor-seal valve is open when the discharge spout is operatively inserted into a fill pipe of a fuel tank, the valve means is open. To this purpose, means are provided to establish communication between the valve means and the flow passage upstream of the nozzle flow control valve and between the valve means and the flow passage in the discharge spout. In one embodiment, the valve means located in the discharge spout at the outlet end thereof is a pinch valve, and in another embodiment, the valve means is a wafer valve. In each embodiment, the valves are operable by the fuel pressure available in the nozzle.
