ABSTRACT:
A hydraulic braking pressure control valve for use in a vehicle includes a main body defining therein a cylinder chamber, a first inlet connected to one end of the cylinder chamber, a first outlet connected together with the first inlet to a first pressure circuit, a second inlet connected to a second pressure circuit and to the other end of the pressure chamber, a control valve including a first piston movably disposed in the cylinder chamber to control the communication between the first inlet and outlet, a second piston receiving the pressure from the second inlet and having a piston rod for engaging with the first piston to displace the same in the direction interrupting the communication between the first inlet and outlet. An annular piston is slidably disposed in an annular space defined around the piston rod to define on one side thereof a pressure chamber, a spring is interposed between the other side of the annular piston and the second piston, and an inertia valve is provided in a passage connecting the pressure chamber with the first inlet.
