ABSTRACT:
An auxiliary hydraulic pressure source device for use with an antilock brake system in a vehicle includes an accumulator that can be reduced in size without deteriorating the performance of the vehicle brakes. The auxiliary hydraulic pressure source device also includes a hydraulic pump for delivering brake fluid into a high-pressure brake fluid output line. A first one-way valve connects this output line with the accumulator only when the hydraulic pressure inside the output line exceeds the hydraulic pressure inside the accumulator by more than a given value .DELTA.P. A second one-way valve connects the accumulator with the output line only when the hydraulic pressure inside the output line is lower than the hydraulic pressure inside the accumulator.
