Pressure profiling device, particularly for dispensing units of pressurized liquids

Abstract

The present invention relates to a pressure profiling device (), particularly for dispensing units of pressurized liquids, comprising a pump () adapted to generate a flow of a pressurized liquid in outlet, said pump () being configured to be connected, by means of at least one delivery duct ('), to at least one dispensing unit (′) of said liquid, a three-way hydraulic fitting (′) being applied to said at least one delivery duct (′), configured to divert a first part of said liquid leaving said pump () into a bypass duct (′), a remaining second part of said liquid continuing on said at least one delivery duct (′), a proportional valve (′) being applied to said bypass duct (′), which can be operated to vary the flow rate of said first part of said liquid diverted in said bypass duct (′) as a function of the degree of opening of said proportional valve (′) so as to vary the pressure of the remaining second part of said liquid, According to the invention, a restriction (') is applied to said at least one delivery duct (′) between said pump () and said three-way hydraulic fitting (′), configured to impose a reduction in the flow rate of said liquid leaving said pump ().
