Abstract

Self-piloted hydropneumatic pump, pressure multiplier, of the type that is constituted by two coaxial internal chambers suitably sized, so that they play some pistons whose displacements determine that the incoming pressure in one of the chambers leaves the other multiplied by a constant value, essentially characterized in that the two internal chambers comprising fluids of different densities, it being provided that the displacement of the pistons inside the chambers is combined, for which purpose the pistons are mounted on a common axis that crosses the dividing partition between cameras, and because the axial displacement of the pistons in one direction or another, is determined by the pressure input in one of the chambers, which is regulated by two pilot valves, coupled in the chamber and located respectively at the beginning and end of stroke of the plunger which valves act indistinctly on a the valve distributes the pressure that feeds the chamber through one of the two inlets of which it is provided, through a circuit that includes a pressure regulator, all arranged in such a way that with the piloting of the valves, it is get a continued work of the pistons.
