Abstract
A pressure transmitter for a brake control system is provided with a piston having a passage extending between an input pressure chamber and an output pressure chamber and a seal fixedly installed on one end of the piston for sealing closing an end of the passage. The seal is resiliently deformable for transmission of pressure between the input pressure chamber and the output pressure chamber. A pressure control valve for a brake control system includes a valve spool for controlling communication between a pressure source and a wheel cylinder for producing a control pressure which is boosted on the basis of a master cylinder pressure and a vehicle running condition, a set of plungers for urging the valve spool in the direction of increasing the control pressure in response to increase of the master cylinder pressure and a solenoid for urging in the valve spool in the direction of causing decrease of the control pressure in response to increase of current supplied to the solenoid.
