DRIVE DEVICE FOR THE IMPOSITION OF OSCILLATIONS OF MASS CURRENT OR PRESSURE ON LIQUID CURRENTS UNDER PRESSURE.

摘要

2.1. MANY TECHNICAL APPLICATIONS NEED ADJUSTMENT ELEMENTS, WHICH CAN BE TRANSMITTED WITH A LIQUID CURRENT, WHICH IS TRANSPORTED UNDER HIGH PRESSURE TO A NOZZLE, WITH A GREAT MODULATION OF MASS CURRENT IN THE FREQUENCY ZONE OF PERCE UP TO APPROXIMATELY 5,000 HZ). A MAIN AREA OF USE OF THIS ADJUSTMENT ELEMENT IS THE ACTIVE DAMPING OF THE COMBUSTION CHAMBER OSCILLATIONS IN BURNERS WITH PRESSURE ATOMIZATION. UNTIL NOW, NO ADJUSTMENT ELEMENT IS KNOWN, WHICH MEETS THIS OBJECTIVE IN THE FREQUENCY ZONE ABOVE MENTIONED WITH RANGE OF NOMINAL VALUES. 2.2. THE MODULATION OF MASS CURRENTS IS EFFECTED THROUGH THE PRINTING OF ACOUSTIC PRESSURE OSCILLATIONS OF LIQUID IN THE AREA OF THE LEVEL OF SOUND PERCEPTION BY MEANS OF FREELY MOVABLE (6) TRAVERS, WHICH ARE DRIVEN THROUGH ELECTROSTRIC ELEMENTS (7) OR MAGNETOSTRICTIVOS. A CHARACTERISTIC OF THE ACTUATOR (1) IS FOUND IN THE DRIVING OF THE ACOUSTIC RESONANCE IN THE CONDUCTING LIQUID (17,18) BETWEEN THE NOZZLE (10) AND THE TRANSPORTATION EQUIPMENT (3), WITH WHICH THE POWER OF THE ADJUSTMENT ELEMENT (1) MAY STILL BE INCREASED IN A CONSIDERABLE WAY. 2.3. THE ACTUATOR ALLOWS IN THE LOWER ZONES OF THE SOUND HEARING LEVEL THE PRINTING OF HIGH MODULATIONS OF MASS CURRENT (UP TO 100% OF MAIN MASS) ON LIQUID CURRENT, WHICH ARE TRANSPORTED UNDER PRESSURE TO A NOZZLE.
