摘要:
The invention relates to a pilot-controlled valve, especially for an anti-skid brake system, this system comprising at least one pressurized-fluid source (90, 115) and at least one pressure receiver, the valve comprising at least one pressurized-fluid inlet (86, 132) and comprising a piston mechanism (54, 114), sliding sealingly in a bore (52) and movable between a rest position and an active position under the effect of an actuating mechanism (17, 18), in order to control an isolating shutter (58, 66) between at least one of the pressurized-fluid sources (90, 115) and at least of the pressure receivers, and a discharge shutter (28) between at least one of the pressure receivers and a reservoir (15), the anti-skid brake system comprising a backfeed circuit including a flow restrictor between at least one of the pressurized-fluid sources (90, 115) and at least one of the pressure receivers. According to the invention, the piston mechanism (54) contains at least one flow restrictor (56, 126) to ensure that the entire backfeed circuit is contained in the piston mechanism (54 ), the pilot-controlled valve also processing a backfeed shutter (44).
