| 20100155502 | METHOD OF GENERATION OF PRESSURE PULSATIONS AND APPARATUS FOR IMPLEMENTATION OF THIS METHOD - 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. | 06-24-2010 |
