ABSTRACT:
A spray nozzle for use in the spray head of shower-bathing apparatus and primarily for use with high pressure water systems. The nozzle comprises a ducted body housing a swirl device having fixed guide vanes extending radially from a generally cylindrical hub and substantially flat guide faces angled relative to the hub axis which impart a swirling motion to water flowing through the body and which direct the water onto a converging wall and thence to a single nozzle orifice of right cylindrical configuration, whereby the water issues as a cone-shaped spray which is "full" of water droplets. The nozzle is suitable for use over a wide range of pressures above 1 bar (1 atmosphere) as the level of comfort of the user is maintained at the higher pressures.
