CENTRIFUGAL NOZZLE Russian patent published in 2023 - IPC B05B3/04 

FIELD: pipe production.

SUBSTANCE: devices for pressure spraying of various process fluids, water. A swirl-type injector comprising an inlet chamber with a central fluid inlet pipe equipped with an elastic insert, a swirl disk with inclined channels and a central rod, a swirl chamber with an outlet and a movable element, characterized in that the swirl chamber is equipped with a movable rotating element in the form of a curved plate, the radial section of which, lying in the plane of the rod, is fixed on it with the possibility of rotation, the plate has a bent end of the arc profile, which is directed in the side opposite to the direction of rotating the moving element, the center of mass of the curved plate is located at a distance of 0.3 to 0.8 radius of the swirl chamber, and the rod at the end has a head located on the side of the outlet to limit the movement of the movable element in the axial direction, the height of the curved plate of the movable element is from 0.2 to 0.8 of the height of the swirl chamber.

EFFECT: increased productivity of the injector at a given inlet pressure P_in and quality of the sprayed fluid, exclusion of wear of the elements of the swirl chamber (cylindrical surface of the swirl chamber and end wall) and the ability to operate the injector at higher inlet pressures, while increasing the reliability of the device.
