ABSTRACT:
The subject invention is directed to a dampening system including a two-roller continuous type dampener, a solution recirculator, and a recirculator adapter. The solution recirculator is configured to supply solution through a supply conduit and to receive solution through a return conduit. A pressure regulator receives solution from the supply conduit and regulates the solution flow. A feed conduit provides fluid communication between the pressure regulator and the dampener's solution reservoir. A venturi receives solution from the supply conduit and induces a vacuum in a suction conduit. A first end of the suction conduit is positioned at a predetermined level within the reservoir and has a portion proximate the first end extending upwardly and away from the reservoir. A second end of the suction conduit is in fluid communication with the venturi. The venturi is in fluid communication with the return conduit.
