Antilock brake control fluid pressure system.

摘要

Disclosed is an antilock brake control fluid pressure system, when in effecting antilock control, fluid is supplied from a pump to the flow valve by way of a second fluid inlet (8). Furthermore, in order to achieve one-way supply of fluid from the master cylinder to the second fluid inlet (8), a check valve (11) is arranged in parallel with a throttle (10) between the master cylinder and the second fluid inlet (8). With the above arrangement, a continuous fluid supply is achieved from the master cylinder to the second fluid inlet (8) by way of the check valve even when no fluid exists in an expansion chamber (12), thereby enabling a metal-edge control at the second fluid inlet allowing the first fluid inlet (7) to be kept in a cut-off condition to thereby suppress reverse pulsation, pump noise, and vibration to the brake pedal.
