Abstract
PURPOSE: To make braking surer by installing an auxiliary control valve within a valve box of a device for a control valve integrally.
CONSTITUTION: An auxiliary control valve Va, equipped with a valve assembly 34 consising of a valve rod 35 having a pressure receiving piston 36, a valve chamber 30, an auxiliary otuput oil pressure chamber G, an auxiliary input oil pressure chamber G, an auxiliary input oil presure chamber F and a spring 37, is installed within a device for a control valve V provided in a second oil passage L2. When a master cylinder M is being operated, pressure-oil sent out of a second output port P2 is flown into a damping chamber A through an input port 4 and is divided for a valve chabmer B and the auxiliary input oil pressure chamber F, thereafter, is provided to rear-wheel brakes Br throuth the auxiliary output oil pressure chamber G and an output port 5. When the pressure of the chamber G is attained to a predetermined valve, the valve assembly 37 descends against the spring 37 and shuts between both chambers F and G. Consequently, even when a weight valve 23 is operated prematurely and shuts a valve port 12 upon running down a steep slope, for example, the oil pressure generated by the master cylinder M is delivered to the rear-wheel brakes Br through the auxiliary control valve Va and a sure braking may be effected.
