キツドブレーキシステムの油圧ユニツト。 3 consisting of an A port that connects to the master cylinder, a P port that connects to the wheel cylinder, and an R port that connects to the reservoir and accumulator.
An anti-skid brake system that operates a port/3 position type solenoid valve to change the flow of hydraulic pressure and reduce, maintain or increase the hydraulic pressure in the wheel cylinder to prevent wheels from locking during braking. In the hydraulic unit, the A port and the R port are communicated with each other at a neutral position of the solenoid valve where the hydraulic pressure in the wheel cylinder is maintained, and a flow path leads from the master cylinder to the reservoir via the solenoid valve. A hydraulic unit for an anti-skid brake system, which eliminates the feeling of a brake pedal being depressed in a hydraulic pressure holding mode.
