ABSTRACT:
Spray nozzle for high pressure cleaning. The spray nozzle comprises a stationary body having an inlet portion and a tubular stem or outlet portion, which has therein a bore and a counterbore, respectively; a plurality of laterally extending ports extending from the counterbore to the exterior of the stem portion for discharge of high pressure water; a rotor having aligned tubular end portions defining a bore and a central rib portion of enlarged diameter having an annular channel or reservoir for water therein, and a plurality of orifices extending from said annular channel so configured as to cause self-rotation of the rotor; and an end cap and a machine screw to hold the rotor in place and restrain it from axial movement. Flow restrictors slow down the speed at which the rotor rotates by momentarily obstructing the discharge of water from the ports in the stem portion as the flow restrictors cross the discharge paths. By slowing down the rotational speed of the rotor, flow restrictors increase the amount of energy in the high pressure water streams discharged from the nozzle. The nozzle of this invention is especially useful in high pressure cleaning applications.
