CAVITATOR Russian patent published in 2014 - IPC B05B1/34 

FIELD: power engineering.

SUBSTANCE: in a cavitator a swirling element is made in the form of peripheral narrowing spiral helicoid channels with an exit into a nozzle. Each spiral channel in the cross section has a shape of a helicoid with the ratio of the small and large axes 0.47…0.75 and with the inner smooth narrowing along the length of the spiral channels. Channels are simultaneously swirled with a number of turns from 1.5 to 2.5 around the conical surface in the form of spirals meeting at the top of the cone with a swirling pitch that increases as the spiral channels narrow. Spiral channels have the main inner ledge and additional inner smooth ledges. The main ledge in shape is made in the form of a geometric surface of the second order from the narrow end of the helicoid. Additional ledges are arranged at the blunt end of the helicoid. Helicoids together with the main and additional internal ledges are swirled around their longitudinal axes of spiral channels with a pitch of 0.9…1.3 from the largest axis of the helicoid in the direction opposite to the direction of swirling of spiral helicoid channels around the conical surface.

EFFECT: increased cavitation effect due to increased speed of liquid movement.
