Abstract:
1. A rotating spray nozzle, comprising: an elongate stem securable to a liquid-supply pipe, the stem defining a passageway therethrough for communicating a liquid from the supply pipe, the passageway communicating at least one inlet opening and at least one outlet opening defined in the stem; and a nozzle body freely rotatably mounted on the stem for rotation about a nozzle axis, the nozzle body having an internal cavity in communication with the at least one outlet opening of the stem, and at least one outlet orifice defined through the nozzle body and communicating with the internal cavity, the at least one outlet orifice being offset from the nozzle axis to impart a driving couple to the nozzle body to cause rotation thereof when a liquid from the supply pipe is communicated through the at least one outlet orifice, wherein the elongate stem defines a longitudinal portion bounded at opposite ends thereof by integral annular shoulders having diameters greater than the longitudinal portion, and wherein further the nozzle body is comprised of two or more separate, mateable portions which are secured together about the stem so that the nozzle body is rotatably captured on the longitudinal portion of the stem between the greater diameter annular shoulders, such that each separate portion of the nozzle body defines a portion of the internal cavity, and the nozzle body defines a pair of opposed, coaxial openings therethrough for receiving the longitudinal portion of the stem, each of the openings communicating with the internal cavity, and each of the openings of the nozzle body being defined by a pair of semi-circular cut-outs, one of said pair of cut-outs being defined in each of the separate portions of the nozzle body.
