ABSTRACT:
A nozzle assembly for a water sprinkler such as a rotary impact head comprising a generally flat member of wear resistant thermoset elastomeric material having an aperture in the central portion thereof constituting the stream defining orifice of the nozzle and a housing member mounting the elastomeric member and a backing member therefor in a sprinkler in flow transmitting relation to a source of water under pressure communicated therewith. The backing member has a central opening through which the stream defined by the nozzle orifice passes and a surface surrounding the opening facing in a direction opposed to the direction of stream movement operable to engage and support the elastomeric member in a deformed operative condition in which first portions of the flat member defining diametrically opposed portions of the periphery of the aperture thereof are disposed in downstream spaced relation with respect to second portions thereof defining diametrically opposed portions of the periphery of the aperture thereof displaced 90.degree. from the first portions so that the stream as it issues from the aperture of the flat member in the aforesaid deformed condition tends to remain flattened in the direction of the first portions and to fan out in a desirable droplet size in the direction of the second portions.
