PCT No. PCT/JP81/00215 Sec. 371 Date May 3, 1982 Sec. 102(e) Date May 3, 1982 PCT Filed Sep. 3, 1981 PCT Pub. No. WO82/00804 PCT Pub. Date Mar. 18, 1982.A hydraulic pressure control valve for an automobile brake mechanism which is provided with a first hydraulic pressure passage communicating with each brake units of, for instance, front wheels, and a second hydraulic pressure passage communicating with each brake units of, for example, rear wheels, and in which a plunger 5 is disposed in at least one or both of the hydraulic pressure passages and at least one hydraulic pressure regulating mechanism for converting the hydraulic pressure of a brake liquid as desire for instance, a poppet valve 14, is provided in association with the plunger in the hydraulic pressure passage having disposed therein the plunger, and in which blocking member is provided for inhibiting the plunger 5 from moving in a direction in which to cut off the brake liquid when the hydraulic pressure of either one of the hydraulic pressure passages fails. The blocking member is composed of a moving member 10 moved by a difference in pressure between the both hydraulic pressure passages and a pressurizing member 17 for generating a pressure on the plunger by the movement of the moving member. |
