管式液圧装置。The hydraulic pressure generated in the two mutually independent hydraulic pressure chambers of the mask cylinder is connected to the vehicle's front left wheel brake and right rear wheel brake, and between the right front wheel brake and the left wheel, respectively, through two mutually independent piping systems. In the X piping type hydraulic device that is transmitted to the rear wheel brake, a pair of proportioning valves are provided in the front wheel piping portions that transmit the hydraulic pressure of the mask cylinder of the two systems to the left front wheel brake and the right front wheel brake, respectively. Alternatively, limit valves are arranged such that their valve pistons are arranged in parallel and their ends face a common air chamber, and the limit valves are placed in the air chamber in a direction perpendicular to the axial direction of the valve piston. It is movable and receives the pressure of the two systems on pressure receiving surfaces facing oppositely to each other, and when both of the two systems are normal, it is in an intermediate position and engages with the ends of the two valve pistons. A common lock piston that prevents the hydraulic pressure control operations of those valve pistons, but moves from the intermediate position to allow the hydraulic pressure control operations of valve pistons belonging to other systems when one system becomes unable to increase the hydraulic pressure. An X-piped hydraulic device for a vehicle brake, characterized in that it is provided with:
