Abstract

The present invention concerns a hydraulic pressure amplifier device comprising a casing () having two chambers () of different cross-sections which house a staged piston () comprising two piston sections () with cross-sections respectively el matching the chambers (), and means () for controlling the movement of the piston (), characterised by the fact that the control means () are formed of an electronic control driven by means for estimating the ends-of-stroke of the piston () without an end-of-stroke sensor or mechanical stop.
