The entrance recess in the chimeric gap of the end plug 13 (reference picture 5) of 12 opening, it is arranged as required to (not scheme in the handle hole of end plug
Show) downwards, without occurring the delay for the recess, handle hole etc. such as rainwater.
As shown in Fig. 2 supercharging magnetic valve 6 and decompression magnetic valve 7 and piston pump 5 are respectively by being arranged at housing 1a's
Cross-drilled hole 14- 1、14- 2Connect and connect, supercharging passes through cross-drilled hole 14 between magnetic valve 6 and decompression magnetic valve 7- 3Connect and connect
It is logical.In addition, master cylinder mouthfuls 9 and wheel cylinder mouthful 10 are arranged at towards the outer surface above housing 1a (device of diagram is upper surface)
The position of opening, in master cylinder mouthful 9 and the supercharging vertical hole 15 that the sidepiece by cam chamber 11 is set between magnetic valve 6- 1, make
Master cylinder mouthful 9 and supercharging magnetic valve 6 are connected with each other.
Equally, also in wheel cylinder mouthful 10 and the decompression vertical hole 15 that the sidepiece by cam chamber 11 is set between magnetic valve 7- 2,
It is connected with each other wheel cylinder mouthful 10 and decompression magnetic valve 7.In addition, cross-drilled hole 14- 1、14- 2Opening portion by reference (omission mark
Number) block.
By forming such construction, the connection operation for the via hole being arranged inside housing 1a is excellent, additionally it is possible to real
The simplification and miniaturization of existing enclosure interior construction.
In addition, supercharging with magnetic valve 6 and decompression magnetic valve 7 mounted in housing 1a and the axis perpendicular of eccentric cam 4
Outer surface f1, the outer surface f1 equipped with these magnetic valves is arranged on by motor 3.
In the brake liquid-pressure control device typically constructed, by motor mounted in side opposite with the outer surface equipped with magnetic valve
Outer surface.On the other hand, in the brake liquid-pressure control device of illustration, motor 3 is arranged on the outer surface equipped with magnetic valve simultaneously
With the magnetic valve 6,7 and motor 3 of the casing 2b covering increase and decrease pressures of electronic control unit 2, therefore, also make motor from rainwater
Deng, and magnetic valve and motor are installed on to the same outer surface of housing, the size of shortening device cam axial direction, with general construction
Brake liquid-pressure control device compared to significantly reducing physique.
In addition, making the housing 1a of the opening of pump assembly hole 12 outer surface be not limited to lower surface.As long as pump assembly hole 12 exists
Downward face opening, it becomes possible to which the chimeric gap of the end plug for obtaining preventing rainwater to be trapped in block pumps assembly hole opening enters stomatodeum
The effect at place etc., as shown in fig. 6, pump assembly hole 12 can also be set in housing 1a upper surface open.
Fig. 6 is the figure for the second method for representing the brake fluid pressure device of the present invention, and piston pump 5 is configured at orthostatism
Cam chamber 11 than housing 1a is by the top.The place that the device of other structures and first method does not change substantially.
That is, it is identical with the device of first method, supercharging magnetic valve 6, decompression magnetic valve 7 are configured in piston pump 5
Both sides, also, make the supercharging magnetic valve 6, decompression magnetic valve 7 and piston pump 5 respectively by being arranged at housing 1a cross-drilled hole
14- 1、14- 2Connection, also, master cylinder mouthfuls 9 and wheel cylinder mouthful 10 are set in housing 1a upper surface open, make master cylinder mouthful 9 and supercharging
With magnetic valve 6 and wheel cylinder mouthfuls 10 and decompression magnetic valve 7 respectively by being arranged at housing 1a vertical hole 15- 1、15- 2Connection.
