Abstract: The device comprises a liquid flow conduit (12), a rotating nozzle (14), which is mounted on a liquid discharge opening (20) of the flow conduit (12) so as to rotate, the rotating nozzle (14) being penetrated by at least one opening (32, 33, 34) for spraying a liquid, a wall (48) for distributing the liquid extending transversely in the flow conduit (12) over the entire cross-section of flow, the wall (48) for distributing the liquid being penetrated by a central conduit (56) for generating a central jet, and at least one tangential conduit (60) for generating at least one tangential jet in the direction of a drive axis, and a wall (50) for driving the nozzle (14), which extends opposite the wall (48) for distributing the liquid and is penetrated by at least one conduit (64) for receiving the or each tangential jet in order to rotationally drive the nozzle. The drive wall (50) is rotationally engaged with the nozzle (14).

Abstract: A valve including a shutter placed in a chamber which is arranged in the valve body and whose end is provided with a seat against which a plug-forming part of the shutter is pressed in the closed position of the valve and is remote in the open position thereof. The inventive valve also includes a magnetic control device provided with the shutter magnetic drive device disposed outside the chamber and displacing the shutter in the closed or open position thereof. The valve is characterized in that the magnetic control device includes at least one ball which is made of a magnetic material, disposed in the chamber and is coupled with an external magnetic drive device, wherein the ball is associated with the shutter in such a way that the shutter is driven in the chamber when the ball is moved by a magnetic drive device.
