ABSTRACT:
The nozzle device having a plurality of spray orifices comprises a nozzle support rotatably mounted about a rotation axis and driveable by the reaction force of pressurized water issuing from the orifices. The nozzle device may be used with high operating pressures, high temperatures, corrosive environments and high-rotational speeds. The current embodiment is particularly designed for cleaning surfaces. A fluid-conducting swivel includes an acceleration nozzle, deceleration nozzle, and support assembly for holding the acceleration and deceleration nozzle with their flow passageways aligned, allowing rotation of one of the acceleration and deceleration nozzles, and maintaining a space between the adjacent ends of the nozzle. The acceleration nozzle includes an acceleration nozzle for accelerating the velocity of the fluid flow to such a velocity that the fluid creates a vena contracta, a substantially self-contained fluid jet. The deceleration nozzle includes a deceleration nozzle for decelerating the velocity of the fluid flow. The deceleration nozzle receives the accelerated fluid from the acceleration nozzle and is sized to substantially prevent expansion of the accelerated fluid and thereby prevent fluid leakage and pressure loss between the acceleration and deceleration nozzles.
