INFO
At the time of urgent braking (When ABS works)
1) Decompressed state
When the wheel is almost locked, the solenoid valve’s port D
12
opens by the “decompression” signal
from the electronic control unit. At this time, the spool 9 of flow control valve compresses the return
valve to close the port B
10 .
Brake fluid which has entered through port A 8 is restricted by the orifice
11
.
Accordingly, the brake fluid from the brake caliper is sent in the line of Port C 14 , Port D 12 then to the
buffer chamber 6 .
The brake caliper fluid pressure is now reduced.
Brake fluid which has been stored in the buffer chamber is pumped by the fluid pressure pump inter-
locked with motor and returned to the master cylinder.
