Claims19
A system for replenishing a primary fluid tank and a secondary fluid tank disposed on a vehicle from a dual dispensing apparatus having a primary fluid reservoir, a secondary fluid reservoir, and a dual nozzle through which the primary fluid and the secondary fluid may flow, comprising:
- a filler neck coupled to the primary fluid tank and the secondary fluid tank;
- and
- an adaptor rigidly attached to the filler neck which is adapted to be coupled to the dual nozzle, wherein said adaptor prevents coupling of a single fluid nozzle that provides a single fluid only.
A system for replenishing a primary fluid tank and a secondary fluid tank disposed on a vehicle from a dual dispensing apparatus having a primary fluid reservoir, a secondary fluid reservoir, and a dual nozzle through which the primary fluid and the secondary fluid may flow, the system comprising:
- a filler neck coupled to the primary fluid tank and the secondary fluid tank, said filler neck has an opening proximate to the exterior surface of the vehicle;
- a member having a base end and a tip end rigidly attached to said filler neck at a location away from said opening of said filler neck, said attachment is made at said base of said member, said tip end of said member projects toward said opening of said filler neck, and is proximate to said opening of said filler neck, wherein a cross-section of said member is contained by a circle of a predetermined diameter from said tip of said member for a predetermined distance along said member;
- a secondary fluid passageway disposed in said member having a receiving end and a downstream end, said receiving end of said secondary fluid passageway is disposed proximately to said tip end of said member, said downstream end of said secondary fluid passageway is connected to said secondary fluid tank;
- and
- a secondary fluid valve disposed in said secondary fluid passageway located proximately to said receiving end.
A method for replenishing a primary fluid tank and a secondary fluid tank disposed on a vehicle from a dual dispensing apparatus having a primary fluid reservoir, a secondary fluid reservoir, and a dual nozzle through which the primary fluid and the secondary fluid may be conducted to a filler neck coupled to the primary fluid tank and a secondary fluid tank, comprising the steps of:
- coupling the dual nozzle with an adaptor rigidly attached to the filler neck, said adaptor allows coupling with the dual nozzle and prevents coupling with a single nozzle that provides a single fluid only;
- and
- providing flow of primary fluid from the primary fluid reservoir to the primary fluid tank.
