Abstract
A fuel dispensing nozzle has a body in which a fuel passage is formed, a spout attached to the body, a poppet valve contained within the nozzle body, for controlling the flow of fuel through the nozzle; a hand operated lever actuates the poppet valve, and the nozzle includes an automatic shut-off mechanism to provide shut-off of the nozzle, when the fuel tank is filled. The automatic shut-off mechanism includes a plunger, a latch pin disposed for vertical movement therein, with the latch pin being embraced by a diaphragm support, of the automatic shut-off mechanism, to provide a lost motion gap which allows the diaphragm to slightly shift, during initiation and dispensing of fuel, and prevent premature shut-off; the latch pin includes an annular upwardly extending collar, that is capable of connecting with a surrounding shoulder formed of the diaphragm support. There is also provided a sleeve-like collar mounted upon the latch pin, to separate the upper end of the plunger from the lower shoulder of the diaphragm support.
