A spray nozzle that includes a nozzle body defining a first surface, a cap defining a second surface able to define an annular nozzle opening therebetween, a turbine having a plurality of radially extending fins circumferentially positioned about the nozzle opening for directing the flow of fluid exiting the nozzle opening, and a reverser member including a cup portion positioned below the cap to intercept the flow of fluid from a flow passage of the cap. The reverser member coupled to the turbine such that the reverser member is caused to rotate in response to rotation of the turbine.

The invention relates to a high-pressure rotor nozzle comprising a main body having a channel for supplying a highly pressurised fluid, a nozzle holder which can be rotationally driven for this purpose via a hydraulically generated torque, and which has at least one nozzle connected to the channel in a manner open for fluid and acting in accordance with an axial recoil, wherein a leakage chamber forming a hydraulic axial bearing during operation is provided between the main body and the nozzle holder that can be axially adjusted in relation to same in a recoil-dependent manner, with said leakage chamber being connected to a first gap seal between the main body and the nozzle holder guiding a leakage fluid, wherein the high-pressure rotor nozzle is designed in such a way that the leakage chamber transitions into at least one throttle gap circumferentially surrounding the nozzle holder in an axial sub-region and varying in the axial extension thereof according to the movement path of the nozzle holder, wherein the throttle gap remains the same height over the axial length thereof.

This disclosure provides an improved nozzle assembly. The nozzle assembly includes a housing having an inlet for directing media (e.g. cleaning fluid) into the housing, and a nozzle core rotatably coupled to the housing. The nozzle core includes a sprayer shaft and a vane coupled thereto. The sprayer shaft defines a peripheral outlet, and is adapted for passage of media from the housing through the outlet. The vane is adapted to receive media from the inlet to rotationally bias the nozzle core in a first direction and radially orient the outlet to an activated position. The nozzle assembly further comprises means for rotationally biasing the nozzle core in a second direction opposite the first to radially orient the outlet to a home position different than the activated position. A system comprising the nozzle assembly, and methods of using each of the same, are also disclosed.
