  • Universal cleaning system utilizing cavitating fluid
    Patent number: 5265629
    Abstract: A unique cleaning method and structure is disclosed which pulses pressurized fluid into a vessel. The pulses clean internal surfaces within the vessel. The internal surfaces may include the internal surfaces of the vessel, or may include items to be cleaned which are placed within the vessel. The pulsed fluid preferably cavitates within the vessel, and impacts upon the surfaces to be cleaned, removing impurities such as scale or other buildup. The fluid may then be directed downstream and recirculated back through the system. Pulses of fluid are cyclically controlled by a control valve to optimize the amount of cavitation within the vessel.
    Type: Grant

  • Heat exchange system utilizing cavitating fluid
    Patent number: 5239948
    Abstract: A unique heat exchange system is disclosed in which pulses pressurized fluid are directed into a vessel. The pulsed fluid preferably cavitates within the vessel, generating heat in the fluid. That heat is then directed to a downstream heat exchange structure where it heats a second fluid medium. The pulses of fluid are cyclically controlled by a control valve to optimize the cavitation within the vessel.
