Abstract
A nozzle assembly includes a channel or tubular member that has openings or slots along its length to permit a passage of solution flowing within the channel or tubular member therethrough. A partition or splitter member is positioned within the channel or tubular member and has a cross-section that outwardly diverges in a direction from an inlet of the channel or tubular member to an end of the channel or tubular member downstream of the inlet. This serves to equalize a pressure of the solution along the length of the channel or tubular member as the solution exits the channel or tubular member through the openings. The nozzle assembly can supply processing solution to a processing path of a processing tank that processes photosensitive material and is structured so as to provide a uniform processing of the photosensitive material within the processing path.
