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.

Abstract translation: 喷嘴头直接由涡轮机旋转，涡轮机由喷嘴入口处的液体压力驱动。 涡轮机由推力轴承支撑，该推力轴承也用作摩擦制动器，以使得当入口压力增加到预定范围时，喷嘴头的转速保持基本上恒定。
