Abstract
A spray nozzle is of a kind including a housing that has a fluid inlet and first and second groups of spray discharge outlets. First and second flow paths are defined in the housing from the inlet to the first and second groups of outlets. Pulsation means in the first flow path cyclically interrupts the flow of fluid from the inlet to the first group of outlets so as to cause a pulsating spray to be discharged therefrom. The second flow path bypasses the pulsation means to cause a continuous non-pulsating spray to be discharged from the second group of outlets. Included are control means for adjustably dividing flow from the inlet between the first and second flow paths. New features include a special resilient seal that serves in part to define the second group of orifices, formation of the control means into a flow-directive plate cooperative with a shutter assembly together with a captivation arrangement for a seal effective between the two, specific stopping arrangements cooperative between the flow-directing plate and the shutter assembly, formation of a portion of the housing into a general tubular body that contains the pulsation means and in which portions of the flow paths are contained together with various arrangements of the same for obtaining adequate sealing between the different components, as well as additional retainer-type sealing arrangements coooperative within the overall structure.
