<p>A device for cavitation treatment of a liquid fuel comprises a chamber (1) provided with an inlet socket (2), on which is mounted a by-pass valve (25), and with an outlet socket (4). The chamber (1) contains two coaxially mounted jet emitters (9, 10) of ultrasonic vibrations, each of them consisting of two blades (11, 12) in the form of Archimedes screw mounted on a base (13) and, by the internal surface (14) of one blade (11) and by the external surface (15) of the other blade (12), forming nozzles (16). One of the jet emitters (9) is rigidly secured in the chamber (1) on the same side as the outlet socket (4). The second jet emitter (10) faces by its blades the first jet emitter (9) and is mounted movably in relation to that emitter (9). The blades (11, 12) of the second jet emitter (10) are located between the blades (11, 12) of the first jet emitter (9) so as to overlap its nozzles (16).</p> |
