  • Patent number: 4380319
    Abstract: A liquid spray nozzle has an outer orificed plate portion with a generally elliptical orifice which tapers in the direction of the water stream and an inner orificed member which has a larger centrally located circular orifice and a pair of smaller circular orifices arranged symmetrically on either side of the central orifice. A centrally located tubular channel member is provided to carry the water stream from a hose or the like such that it passes through the inner and outer orificed members. Means are provided for rotating the orificed members relative to each other. In a first position where the smaller orifices of the inner plate are positioned opposite the corners of the elliptical orifice of the outer plate, a flat, fan-shaped spray is produced. When one of the orificed members is rotated to a position 90.degree. from this first-mentioned position whereat the smaller inner circular orifices are covered by the outer orificed plate, a high-force, narrow cylindrical water stream is provided.
