Abstract
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.
