Abstract

Improvements in the hydraulic pressure elevators, constituted by a pressure booster with twin pumps that includes two circulation units in which the establishment of the pressure flow characteristic for each pump is carried out by means of a hydraulic flow control device comprising a feedback tube and an adjustable stopcock that controls the coupling to both the inlet tube and the outlet tube, characterized in that the flow control assembly consists of a single feedback and an adjustable stopcock only, with which the inlet pipes and the outlet pipes of the two circulation units can be coupled, is incorporated, constituting an apparatus in a single block.
