<p>A liquid spraying device comprises a nozzle (2) formed with an outlet orifice (10) through which the water exits as a jet flowing parallel to the axis of the nozzle (2), a cup member (12) supported close to and overlying the outlet orifice (10) so as to be impinged by the jet and to reflect it back towards the nozzle (2), and a deflector surface in the path of the reflected-back liquid, which deflector surface is formed with at least one channel (40) extending generally radially of the nozzle (2) and effective to deflect the reflected-back liquid and to channel it to form at least one jet issuing laterally of the nozzle (2). Described are a static-type device in which the deflector surface is formed in the face (24) of the nozzle (2) having the outlet orifice (10), and rotary-type devices in which the deflector surface is formed in a rotor mounted between the cup member and the face of the nozzle having the outlet orifice.</p> |
