Abstract
A multiple dosing device for the uniform dosing of liquids includes a plurality of dosing elements each including a dosing plunger; end connecting plates; sealing elements, interposed between the faces of adjacent dosing elements and between the faces of a dosing element and a connecting plate; and tie rods holding the dosing plates, end connecting plates and sealing elements together. The dosing plunger movement is controlled in one direction by a fluid pressure and in the opposite direction by the liquid which is under pressure. Diaphragm valves are formed on both faces of the dosing element through cooperation among the dosing element, an interposed sealing element, and a connecting plate.
