  • Patent number: 7934666
    Abstract: An acoustic generator of pressure pulsations includes a cylindrical waveguide which is caused to vibrate at a low amplitude by an electromechanical transducer. The vibration of the cylindrical waveguide creates low amplitude pressure pulsations in an acoustic chamber containing stationary pressure fluid. A mechanical amplifier, which is part of the acoustic chamber, amplifies the low amplitude pressure pulsations generated by the cylindrical waveguide.
    Type: Grant
    Filed: March 4, 2010
    Date of Patent: May 3, 2011
    Assignee: Institute of Geonics ASCR, V.V.I.

  • Publication number: 20080135638
    Abstract: The method of generation of pulsations of liquid jet consisting in that acoustic pulsations generated by acoustic actuator act directly or indirectly on the pressure liquid in acoustic chamber; generated pressure pulsations are amplified by mechanical amplifier of pulsations and transferred by liquid waveguide fitted with pressure liquid feed to the nozzle and/or nozzle system. Resonant natural frequency of the acoustic system can be matched to the frequency of acoustic pulsations by means of a tuneable resonant chamber.
