Abstract
The invention relates to a brake regulator interposable between a hydraulic pressure source and a motor-vehicle brake circuit, of the type comprising a housing equipped with a bore, a simple or differential piston sliding in the bore and delimiting there a first (18) and a second (20) pressure chamber capable of being connected to the pressure source and to the brake circuit respectively, the chambers (18, 20) communicating with one another by means of a passage made in the piston, a valve mounted in the passage and stretched elastically to bear sealingly against a seat formed on the piston, and a return boring interposed between a movable element, the position of which varies as a function of the load of the vehicle, and the piston, so as to stress the latter toward the bottom of the second chamber (20), in a rest position in which the valve is set apart from its seat by a stop (30). The bottom (15) of the second chamber (20) assumes a reentrant shape, the piston (16) comprises a tab (44) projecting opposite the substantially lowest part (13) of the bottom (15), and the stop (30) mounted movably relative to the bottom (15) rests on the bop of a preformed washer (40) forming a leve…
