ABSTRACT:
A self-cleaning spray nozzle in which a standard fitting serves as the nozzle body. A unitary valve assembly is inserted partially into the fitting and secured to it. The valve assembly includes a secured valve seat biased by a spring into a spraying head so that the valve seat and spraying head form a seal. The spraying head is designed so that it does not form a complete seal with the valve seat, the gap in the seal defining a metering orifice so that under normal fluid pressures, fluid will spray out of the orifice in a predetermined pattern. When a force sufficient to overcome the spring bias is applied to the spraying head, the spraying head separates from the valve seat breaking the seal and allowing the fluid to flush the outlet. The force can either be applied manually, or caused by an increase in fluid pressure. An optional deflection collar may be snapped onto the nozzle for influencing the direction of the spray.
