ABSTRACT OF THE DISCLOSURE Pressure control device comprising a manual valve (VM) associated with a pressure control valve (VRP), includes a first line pressure (PL), defined by two calibrated jets in series, which are placed on a duct set at zero pressure by the manual valve (VM) being in a first position R. At a second line pressure range (PL), a duct is fed at line pressure (PL), the manual valve (VM) is in a second position A. A variation of line pressure (PL) is assured by a modulating solenoid valve (EVM), which establishes a modulated pressure (PM) acting on a differential section (.SIGMA.) of said pressure control valve (VRP).
