1 1, 31 hydraulic oil discharged respectively to 2 through one of the annular groove 26 and the inlet hole 29 1 of the connection boss 12 1 flows into the 1 Tsugiryuro 19, also other side pair of solenoid valves 2 3, 2 4
From the outlet chamber 31 3, 31 hydraulic oil discharged respectively to 4 of the other connecting boss 12 second inflow grooves 27a and the inlet hole 29
Similarly, it flows into the primary flow path 19 through 2 . And FIG.
As indicated by the arrows in FIG. 1, the hydraulic fluid flows through the primary flow path 19 towards its outlet, the end of the bulkhead 18, then around the said end and into the secondary flow path 20, down there from the said end. effluent from the farthest connecting the outflow hole 30 of the boss 12 2 grooves 27
After flowing through the delivery passage 5 through b, it is sucked and pressurized by the hydraulic pump 6, and is supplied to pressure oil for control of each wheel brake.

トから外部へ放出していく。By the way, since the hydraulic oil discharged from the electromagnetic valve 21 to 24 is a relatively high pressure, the outlet chamber 31 1-31
In 4 the vigorous agitation of the hydraulic oil occurs, generating a large amount of air bubbles. Therefore, the hydraulic oil flowing into the primary flow path 19 contains a large amount of air bubbles, and while the hydraulic oil passes through the long flow path composed of the primary and secondary flow paths 19 and 20 as described above. The bubbles are separated from the hydraulic oil, and the separated bubbles float on the oil surface of the reservoir 7 and are discharged to the outside from an air vent (not shown) of the cap 11.

のを阻止し得る。At this time, since the upper surface of the primary flow path 19 is closed by the cover plate 21, the bubbles separated in the primary flow path 19 flow to the outlet of the primary flow path 19 farthest from the outlet hole 30. When it arrives, it will be released from the cover plate 21, and therefore, although the two flow paths 19 and 20 are adjacent to each other,
Bubbles flowing in the primary flow path 19 can be prevented from entering the secondary flow path 20 side.
