Abstract

A spray nozzle head is rotated directly by a turbine which is driven by the pressure of liquid at the inlet of the nozzle. The turbine is supported by a thrust bearing which also acts as a friction brake to cause the rotational speed of the nozzle head to remain substantially constant as the inlet pressure increases through a predetermined range.
