BRAKE PRESSURE CONTROL VALVE AND BRAKE CONTROL DEVICE

摘要

Disclosed is a brake pressure control valve (20) that is equipped with a block (31) in which at least first holes (31a, 31b) and two second holes (31c, 31c) have been formed, variable load valves that are disposed in the first holes (31a, 31b) and are capable of generating load compensation pressure in response to a vehicle load, and relay valves (22, 22) that are each disposed in the second holes (31c, 31c) and are capable of generating brake pressure. The relay valves (22) are each equipped with membrane plates (22f) that are disposed in a manner so as to project laterally from a piston (22e) while reciprocatably supporting the piston (22e). Two relay valves (22, 22) are disposed in horizontal alignment with a space therebetween in a manner such that the membrane plates (22f) thereof are mutually adjacent. The variable load valves are disposed in a position that is between two pistons (22e) while diverging from the position at which the membrane plates (22f) are mutually adjacent.
