Abstract
A fluid dispensing nozzle includes a removable valve subassembly that controls the flow of fluid and the recovery of fluid vapor through the body of the nozzle. The subassembly may be pre-assembled and installed within a nozzle body as a single unit. The nozzle may include a vacuum-driven automatic shut-off system which prevents fluid from flowing through the nozzle when the downstream end of the nozzle spout is submerged. The shutoff system may also be magnetically actuated to allow for dry testing in which the automatic shut-off functionality is testing without dispensation of fluid.
Claims16
A nozzle for dispensing fluid, the nozzle comprising:
- a nozzle body having an inlet end and an outlet end;
- a self-contained valve subassembly receivable within and separable from said nozzle body as a subassembly, said valve subassembly comprising:
- a fluid control component moveable between an open position and a closed position;
- an intermediate component;
- a fluid control valve having a valve body and a valve seat, said fluid control valve moveable from a closed position in which said valve body is seated in said valve seat to an open position in which said valve body is spaced away from said valve seat, said fluid control valve moveable to its open position when said fluid control component is in its open position,
- a vapor control component moveable between an open position and a closed position;
- a carriage sized to receive said fluid control component and said vapor control component, securement of said carriage to said intermediate component capturing said fluid control component, said fluid control valve and said vapor control component between said carriage and said intermediate component to form said self-contained valve subassembly;
- and
- a vapor control valve operably coupled with said vapor control component, said vapor control valve moveable between a closed position and an open position in response to a corresponding movement of said vapor control component.
A method of assembling a nozzle comprising the steps of:
- pre-assembling a self-contained valve subassembly, the step of pre-assembling including:
- installing a fluid control component into a carriage, such that the fluid control component is moveable within the carriage between an open position and a closed position;
- installing a fluid control valve proximal said fluid control component, such that said fluid control valve is in a closed position when said fluid control component is in its closed position;
- installing a vapor control component into said carriage, such that the vapor control component is moveable independently of said fluid control component within the carriage between an open position and a closed position;
- and
- coupling a vapor control valve to said vapor control component, such that said vapor control valve is in a closed position when said vapor control component is in its closed position;
- inserting said self-contained valve subassembly into a nozzle body of the nozzle along a direction of insertion;
- and
- attaching a coupler to said nozzle body, the coupler urging said valve subassembly in the direction of insertion to couple said valve subassembly with said nozzle body.
