Abstract
A rotating spray nozzle has a nozzle mounting member, for attachment to a supply pipe. A nozzle body is rotatably mounted on the nozzle mounting member, and includes at least one, but preferably two, slot-shaped nozzles. Each slot-shaped nozzle generates a fan-shaped spray in a plane. Each nozzle is inclined to intersect the axis of the nozzle axis, to ensure thorough distribution of spray, on either side of the nozzle body, across the nozzle axis. The slot-shaped nozzles can be formed as slots in a unitary nozzle body.
Claims14
A rotating spray nozzle comprising:
- a nozzle mounting member adapted for fitting to a supply pipe;
- a nozzle body rotatably mounted on the nozzle mounting member, for rotation about a nozzle axis, and having an internal cavity in communication with the nozzle mounting member, for supply of fluid;
- and a pair of slot-shaped nozzles in the nozzle body, extending from the internal cavity and each defining a nozzle plane that inersects the nozzle axis, wherein the slot-shaped nozzles intersect the nozzle body on generally opposite sides of the nozzle body and each nozzle is offset from the nozzle axis, to impart a driving couple to the nozzle body, to cause rotation thereof, and wherein one nozzle is inclined to produce a spray pattern intersecting the nozzle axis, adjacent one end of the nozzle body, remote from the nozzle mounting member, and the other nozzle is inclined to produce a spray pattern intersecting the nozzle axis proximate the nozzle mounting member, adjacent the other end of the nozzle body.
