ABSTRACT:
A manifold and valve block assembly, particularly for a bottle washer designed for plastic returnable bottles. The manifold and valve block assembly provides for the successive supply of a plurality of different cleansing and sanitizing solutions, and also for residual fluid removal and drying, to an internal spray nozzle positioned within a bottle being cleaned, and also to spray nozzles positioned externally of the bottle. The internal spray nozzle is mounted on a lance which is driven by different fluids between a fully retracted position within the valve block assembly and a fully extended position in which it is positioned within a bottle being cleaned. The lance is longitudinally movably positioned within a drive cylinder, and has a central fluid flow passageway which communicates with the spray nozzle mounted on the upper end thereof. A plurality of valves are mounted in the valve block assembly, including a static air valve which supplies air under pressure to the top of the lance to drive it downwardly to its retracted position. Several of the valves supply different cleaning and sanitizing solutions, and also air for residual fluid removal and drying, to a common manifold which provides a fluid passage to the central fluid flow passageway of the lance for the fluids to be sequentially sprayed through the nozzle.
