Claims

[Scope of utility model registration request]

A valve body is formed with a stepped cylinder whose diameter gradually increases in a concentric series from one end to the other end, and a driven valve mechanism and hydraulic balance mechanism are installed inside the cylinder. and an active proportioning type valve mechanism installed in a position biased toward the larger diameter cylinder from the installation position of the intermediate cylinder member, and is capable of controlling output hydraulic pressure reduction in the active valve mechanism. Accordingly, in the dual piping hydraulic pressure control device for a vehicle brake system configured such that the driven system valve mechanism performs pressure reduction control of the output hydraulic pressure via the balance mechanism, the outer periphery of the middle cylinder member includes:
By assembling two seal members spaced apart in the axial direction that slide into the cylinder in the housing part of the balance mechanism, and by providing stepped cross-sectional areas of these seals, the hydraulic biasing force on the driven system side is increased. For double piping, the seal leak detection opening facing the outer periphery of the middle cylinder member between the two seal members is provided on the larger diameter side of the middle cylinder member. Hydraulic pressure control device.
