Title:
BRAKE PRESSURE CONTROLLER FOR VEHICLES
Document Type and Number:
WIPO Patent Application WO/1996/007571
Kind Code:
A1
Abstract:
SM valves 50FL, 50FR are changed over to communication positions for opening a conduit at the time of turn-off of a power supply and to cut-off positions when power is supplied from a brake control device (30). Since these SM valves 50FL, 50FR have an integral structure with a pressure-regulating valve, the term "cut-off position" means the position (pressure-regulating position) at which they function as a pressure-regulating valve for opening the conduit when a pressure from W/C 2FL, 2FR side exceeding a predetermined level is applied. Throttles 50FLS, 50FRS for imparting a pressure between these throttles and an opening/closing position are disposed towards an M/C 34 side from the opening/closing position at which communication/cut-off of the SM valves 50FL, 50FR is made. In this way, vapor lock can be prevented by preventing aeration which occurs when a high oil pressure is applied to the M/C side.
