Abstract

An improved nozzle for a liquid dispensing valve of the automatic shutoff type placed at the end of a hose for the filling of automobile tanks is euipped with an automatic pneumatic device which shuts off the valve when the tank is filled to a level near the edge of the tank filler hole, comprising venturi and passage means controlled by a manually-operated lever which, when the valve is open, generates a negative pressure in an associated conduit within the main liquid outlet tube, the associated conduit being closed off at its end and slightly shorter than the main tube in which it is incorporated, part of the external wall of the associated conduit corresponding, at least at its end, to part of the internal wall of the main tube. The control of the shutoff means is effected by a manually-operated lever and through a mechanical linkage which includes an element for breaking this mechanical linkage, thereby allowing the means to stop the dispensing of liquid without moving the lever, the element being controlled by the device sensitive to the negative pressure generated by the venturi means to which the said device is connected through the associated conduit and a calibrated lateral hole made in the end of this associted conduit leading out to the ambient free air. A second calibrated hole is provided at the end of the associated conduit and in its axis leading into the main tube and a third hole of larger diameter is located laterally in the main tube, downstream of the end of the associated conduit and in its immediate vicinity, leading out to the ambient air, so that when the liquid in the tank covers almost simultaneously the three orifices of the end of the valve, the simultaneous increase in the pressure drop in the two calibrated orifices produces the immediate operation of the automatic-shutoff device of the valve.
