Abstract
A nozzle body of a molded spray head forms a path for a highly pressurized carrier fluid. The fluid path includes a rectangular-section, diverging outlet and a spray nozzle spaced upstream therefrom in a suction chamber for directing the carrier fluid in a spray pattern spaced inwardly of and parallel to the walls of the diverging outlet. A chemical product is selectively passed into the suction chamber for entrainment about the carrier fluid. Avoiding impingement of the carrier fluid spray upon the walls of the nozzle outlet helps to maintain the 600-1000 psi pressure of the carrier fluid flow throughout the nozzle body for increased impact pressure upon surfaces to be sprayed.
