Abstract

PURPOSE:To provide a by-pass function in a braking oil pressure control device having two series of braking oil circuit by installing valve transfer pistons which pull a pressure receiving piston when one of the series fails between two pressure receiving pistons which perform proportional pressure reduction action. CONSTITUTION:Each series L1 or L2 of a braking oil circuit C has a pressure receiving piston 91 or 92 and a valve 231 or 232 respectively constituting a proportional valve together with a pressure adjusting spring 12, valve transfer pistons 111 and 112 being installed between the pressure receiving pistons 91 and 92, stoppers 271 or 272 provided at the ends thereof acting on the valves 231 or 232 respectively. When the series L2 fails for example both the valve transfer pistons 111 and 112 move to right as there is no pressure in a chamber 182, and a seat 161 pulls the pressure receiving piston 91 and the valve 231 is held open by the stopper 271. Thus, the series L1 does not perform the pressure reduction action providing a by-pass function.
