  • Material treating apparatus including pneumo-hydraulic vibrator
    Patent number: 4070275
    Abstract: Material treating apparatus including one or more pneumohydraulic vibrators. The apparatus includes a container with cells separated by at least one valve lying on a supporting frame, the valve having a movable valve element which is urged toward its valve-closed position by springs. On one side of the valve there is an air cell connected with a source of air under pressure, and on the other side of the valve there is a second cell containing a liquid or a liquid suspension of material to be treated. When the air cell is subjected to air under pressure the movable valve element vibrates and generates intensive vibro-pulsation turbulent streams in the liquid material in the second cell.
