Abstract

"FLUID OVERPRESSURE SYSTEM", for supplying a variable flow rate of a fluid to be distributed under a required pressure level, comprising: a source of fluid to be distributed under variable pressure; a source of engine fluid under pressure; an overpressure driven by motor fluid to combine the pressures of the engine fluid and the fluid to be distributed received and supply the fluid to be distributed under the combined pressure; a regulating device for regulating the pressure of the motor fluid supplied to the overpressure; and ducts for supplying the motor fluid under said regulated pressure and the fluid to be distributed under said variable pressure to said overpressure; characterized in that said regulating device comprises: a valve having an inlet connected to the motor fluid source and an outlet for the motor fluid under said regulated pressure; and means for controlling said valve, comprising: a first pilot element sensitive to pressure, in relation to the outlet of said valve, a second pilot element sensitive to pressure, in relation to the path of the superpressor intended for the entrance of the fluid to be distributed, the ratio of the active area of the first pilot element to the active area of the second pilot element being approximately equal to the ratio of transmission of the supercharger, and opposite means for requesting said valve to be opened.
