Improvements in the dosing pumps of liquidos.consistent in a pump with a mechanical part and another hydraulic. The mechanical part has a speed reducing system, consisting of a crown that have in its axis excentricas that transform the transition transmitted by an endless axis (7), moved by an external motor, in a longitudinal movement that moves the piston ( 3) from the hydraulic part at a adjustable speed with the length of the pack (4), at a voltage from the outside. It has input, output and pressure limiting valves (18) concrete for the excess of liquid to the storage place. (Machine-translation by Google Translate, not legally binding)
