Abstract
A fuel dispensing nozzle of a fuel dispensing system comprising a lockout mechanism that prevents the delivery of fuel when the fuel nozzle is not inserted into a fuel reservoir. The fuel dispensing nozzle includes a lookout plunger selectively restrained from movement by a rocker arm. The rocker arm maintains a freely moveable condition or a constrained turn movement condition based on the status of the fuel nozzle.
Claims10
A fuel dispensing nozzle comprising:
- a nozzle body, said nozzle body defining a nozzle body fuel passageway and a diaphragm cavity;
- a fuel delivery spout extending from said nozzle body, said fuel delivery spout defining a spout fuel passageway, said nozzle body fuel passageway in fluid communication with said spout fuel passageway to form a nozzle passageway capable of conveying a quantity of fuel from a source of said quantity of fuel through said nozzle body and said spout to a fuel reservoir;
- a fuel valve disposed in said nozzle passageway, said fuel valve actuatable to allow a flow of said fuel through said nozzle passageway;
- a lockout plunger including a longitudinal axis, said lockout plunger having an active configuration allowing actuation of said fuel valve and an inactive configuration preventing actuation of said fuel valve;
- a rocker arm rotatably supported relative to said nozzle body, said rocker arm rotatable to a stop position maintaining said lockout plunger in said inactive configuration preventing actuation of said fuel valve;
- and
- a spring positioned and oriented to selectively supply a spring bias to said rocker arm, said rocker arm rotatable over a range of motion, said rocker arm having an operative condition in which said rocker arm is freely rotatable over said range of motion, whereby said spring bias does not influence movement of said rocker arm in said operative condition, said rocker arm having a stop condition in which said spring bias maintains said rocker arm in said stop position to maintain said lockout plunger in said inactive configuration preventing actuation of said fuel valve.
