Abstract
Valve mechanism for volumetric measuring devices, of the type in which the displacement and dosage of liquids takes place by means of a cylinder that contains an independent piston activated by the thrusts of the liquid itself, in which the bases of said cylinder have an inlet mouth and another outlet, corresponding to two conduits, equipped with a valve that determines the closing or opening of the passage, characterized by the fact that in each base of the cylinder, the two valves are antagonistic and are governed by a rocker which is articulated with the corresponding shutters of that valve, in order to open a valve while closing the remaining, being related to each other the two rockers by an articulated lever, equipped with mechanical elements for longitudinal adjustment, which lever receives the alternative drives from an automatic control device, or possibly activated by the device itself, c in order to produce reverse effect maneuvers for the valves of each of the cylinder bases.
