  • System for transferring dry flowable material
    Patent number: 4545410
    Abstract: A system for transferring dry flowable material includes a substantially closed vessel having an inlet and a discharge end. A cycle valve and venturi are arranged between a source of fluid pressure and the vessel such that the cycle valve may be selectively actuated to pass pressurized fluid directly to the vessel or through the venturi. A suction line interconnects the vessel to the throat section of the venturi such that passage of fluid flow through the venturi establishes a suction within the vessel.
