Abstract

PURPOSE: To increase a braking power while preventing wheels from being locked, by designing a liquid pressure control valve, in which a sealing pressure corresponding to the degree of deceleration is generated by an operation of a deceleration sensitive valve, such that a critical brake liquid pressure for rear wheels can be varied in accordance with the sealing pressure.
CONSTITUTION: A liquid pressure control valve is adapted to supply, when a brake pedal 44 is stepped, a liquid pressure Pm from a master cylinder 41 to rear wheel cylinders 42, 43 as a liquid pressure Pr via a port 8, a chamber 4, a small bore 3b in a plunger 3, a gap between a valve body 11 and a valve seat 12, a port 12a, a chamber 5 and a port 9. The liquid pressure control valve has a deceleration sensitive valve which is adapted to compress springs 32, 34 via a piston 13 by a sealing pressure in a chamber 14, which is in accordance with the degree of deceleration, when the deceleration has exceeded a predetermined level. The above-mentioned piston 13 consists of a stepped piston which is adapted to be operated only when a constant sealing pressure is applied to one pressure receiving portion thereof with a sealing pressure of a level higher than a predetermined level applied to the other pressure receiving portion thereof via a defferential pressure valve 21.
