Claims

[Scope of utility model registration request]

(1) In a series hydraulic pressure control valve for controlling two systems in which a pair of pressure reducing valves that reduce the input hydraulic pressure of mutually independent systems and output it are arranged in series, the housing that houses the pressure reducing valves is
A series hydraulic control valve for controlling two systems, characterized in that the divided housing members are integrated by press fitting or caulking by plastic deformation and thermal deformation, either directly or through other members.

(2) A utility model according to claim 1, wherein each of the divided housing members is provided with a mounting hole for directly or indirectly fixing the control valve to the vehicle body. Series hydraulic pressure control valve for two systems.

(3) Registration of a utility model characterized in that a support member that is slidable in the axial direction and liquid-tightly supports the hydraulic pressure responsive plunger of each of the pressure reducing valves is fixed to each housing member, respectively. A series hydraulic pressure control valve for controlling two systems according to claim (2).
