Power washer spray head

摘要

A spray head for a powdered power washer designed to produce a wide diameter spray of water under both high and low water pressure conditions. The washer head includes a spinner tube mounted inside a cylindrical-shaped nozzle body. The upper segment of the spinner tube is held inside the nozzle body by a fixed cassette assembly. A middle and lower segments of the spinner tube extend below and are bent outward and axially offset from the upper segment and from each other. Mounted inside and over the upper end opening of the nozzle tube is an adapter with a threaded cavity formed on one end. The adapter includes a water orifice that delivers water from the handle or wand to the spinner tube. A flat washer with a narrow water orifice is used to deliver a narrow, high velocity stream of water to the spinner tube.

主权项

1. A spray head for a handle or wand used with a low to high water pressure powered washer, comprising:
a. a hollow, cylindrical-shaped nozzle body with a threaded top opening that attaches to a handle or wand on an powered pressure washer, said nozzle body includes a central bore formed therein; b. an adapter located inside said nozzle body and attached to said top opening on said nozzle body, said adapter also includes a central water passageway that allows water delivered to said adapter to be transmitted through said adapter; c. a flat washer located inside said nozzle body and below said adapter, said flat washer includes a central orifice slightly smaller that said water passageway formed on said adapter; and, d. a rotating spinner tube located inside central bore in said nozzle body, said spinner tube includes an upper segment, middle segment, and a lower segment, said upper segment being longitudinally aligned inside said central bore, said middle segment being outward and diagonally aligned with said upper segment, and said lower segment be radially aligned with said middle section so that a rotation force is exerted on said spinner tube when water is forced from said lower segment, said middle segment being bent outward 3 to 8 degrees from said upper segment, said lower segment being outward 3 to 8 degrees from said middle segment, said middle segment and said lower segment being sufficient in length so that said spinner tube may rotate freely inside said central bore of said nozzle body.
