A nozzle for use in a non-overflow liquid delivery system comprises a nozzle body, a liquid delivery conduit having a liquid-receiving inlet and a liquid-dispensing outlet, and a non-bifurcated liquid recovery conduit having a liquid-receiving inlet and a liquid-conveying outlet. The minimum effecti
A nozzle for use in a non-overflow liquid delivery system comprises a nozzle body, a liquid delivery conduit having a liquid-receiving inlet and a liquid-dispensing outlet, and a non-bifurcated liquid recovery conduit having a liquid-receiving inlet and a liquid-conveying outlet. The minimum effective internal cross-sectional area of the liquid recovery throughpassage is greater than half the minimum effective internal cross-sectional area of the liquid delivery throughpassage. A valve has a first movable valve portion and a second movable valve portion that are interconnected one to the other for co-operative movement one with the other. A manually operable trigger is connected to the first movable valve portion for corresponding positive uninterruptable movement of the first movable valve portion between a valve-closed configuration and the valve-open configuration.

1. A nozzle for use in a non overflow liquid delivery system for delivering liquid into a destination container, and recovering excess liquid from said destination container, said nozzle comprising: a nozzle body;a spout connected to the nozzle body, the spout and the nozzle body being configured to provide non-sealing engagement of the nozzle with the destination container;a liquid delivery conduit carried by said nozzle body and having a liquid receiving inlet and a liquid dispensing outlet interconnected one with the other in fluid communication by a liquid delivery throughpassage; and,a liquid recovery conduit carried by said nozzle body and having a liquid receiving inlet and a liquid conveying outlet interconnected one with the other in fluid communication by a liquid recovery throughpassage. 2. The nozzle of claim 1, wherein the minimum cross sectional area of said liquid recovery throughpassage is equal to or greater than the minimum cross sectional area of said liquid delivery throughpassage. 3. The nozzle of claim 1, wherein the minimum cross sectional area of said liquid recovery throughpassage is equal to or greater than twice the minimum cross sectional area of said liquid delivery throughpassage. 4. A nozzle for use in a non overflow liquid delivery system for delivering liquid into a destination container, and recovering excess liquid from said destination container, said nozzle comprising: a nozzle body;a spout connected to the nozzle body, the spout and the nozzle body being configured to provide non-sealing engagement of the nozzle with the destination container;a liquid delivery conduit carried by said nozzle body and having a liquid receiving inlet and a liquid dispensing outlet interconnected one with the other in fluid communication by a liquid delivery throughpassage; and,a non bifurcated liquid recovery conduit carried by said nozzle body and having a liquid receiving inlet and a liquid conveying outlet interconnected one with the other in fluid communication by a liquid recovery throughpassage. 5. The nozzle of claim 4, wherein said liquid recovery conduit is generally disposed within said liquid delivery conduit. 6. A method of delivering liquid to a destination container and precluding overflow from the destination container while having liquid delivered thereto where a liquid dispensing outlet and a liquid receiving inlet of a nozzle are placed into the destination container and the liquid receiving inlet defines a fill level, said method comprising: permitting delivery of liquid from said liquid dispensing outlet into said destination container while the nozzle is in non-sealing engagement with the destination container;when the liquid in said destination container reaches said liquid receiving inlet: receiving liquid from said destination container into said liquid receiving inlet; and,permitting recovery of liquid from said destination container at substantially the same rate as liquid is being delivered into said destination container while the nozzle is in non-sealing engagement with the destination container. 7. The nozzle of claim 1, wherein the minimum cross sectional area of said liquid recovery throughpassage is equal to or greater than one half the minimum cross sectional area of said liquid delivery throughpassage. 8. The nozzle of claim 1, comprising at least one openable and closable valve having a first movable valve portion selectively movable between a valve closed configuration whereat liquid is precluded from being dispensed from said liquid dispensing outlet of said liquid delivery conduit and a valve open configuration whereat liquid is permitted to be dispensed from said liquid delivery conduit. 9. The nozzle of claim 8, comprising a second movable valve portion selectively movable between a valve closed configuration whereat liquid is precluded from egressing from said liquid receiving inlet of said liquid recovery conduit and a valve open configuration whereat liquid is permitted to egress from said liquid recovery conduit. 10. The nozzle of claim 9, wherein said first movable valve portion and said second movable valve portion are interconnected one to the other for cooperative movement one with the other. 11. The nozzle of claim 9, wherein said first movable valve portion and said second movable valve portion are interconnected one to the other for concurrent movement one with the other. 12. The nozzle of claim 9, wherein said first movable valve portion and said second movable valve portion are integrally formed one with the other for concurrent movement one with the other. 13. The nozzle of claim 1, wherein said liquid dispensing outlet of said liquid delivery conduit and said liquid receiving inlet of said liquid recovery conduit are disposed adjacent each other. 14. The nozzle of claim 8, wherein said first movable valve portion is disposed adjacent said liquid dispensing outlet of said liquid delivery conduit. 15. The nozzle of claim 9, wherein said second movable valve portion is disposed adjacent said liquid receiving inlet of said liquid recovery conduit. 16. The nozzle of claim 1, wherein the spout is configured for insertion into said destination container. 17. The nozzle of claim 16, wherein a portion of said liquid delivery conduit is carried by said spout. 18. The nozzle of claim 17, wherein a portion of said liquid recovery conduit is carried by said spout. 19. The nozzle of claim 1, wherein said liquid recovery conduit is generally disposed within said liquid delivery conduit. 20. The nozzle of claim 8, further comprising a manually operable trigger movable between a rest position and at least one in use position, and operatively connected to said valve for permitting selective operation of said valve between said valve closed configuration and said valve open configuration.
