    摘要: The present invention is an air operated fluid handling apparatus for cleaning lithographic presses. It provides a printing press operator with a device for both dispensing ink solvents and removing spent fluids used in the printing process. Compressed air is regulated and directed to a T-section connector. One conduit extends from the connector to provide pressure in an ink-solvent container. Another conduit extends from the connector to a venturi which is used to create a vacuum in a used-fluid container. A conduit extends from each container and connects to a light weight flexible hose. Connected to the opposite end of the flexible hose is a valve and nozzle assembly that allows the press operator to alternate between dispensing ink solvent and remove spent fluid. With this apparatus the press operator can effectively move from printing head to printing head dispensing ink solvent and removing used fluids as necessary for ink train and dampening system cleanup.

    摘要: 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.
