ABSTRACT:
A pressure reducer device, particularly for hydraulic brake systems in motor vehicles comprises a housing having a chamber, a differential area piston movable within the chamber having a passage through which pressure is transmitted from a high pressure chamber to a low pressure chamber, and a sleeve fixed to the housing and disposed in the high pressure chamber. The differential area piston is movable in the sleeve to open and close the passage to perform a pressure modulating operation on the fluid transmitted from the high pressure chamber to the low pressure chamber.
