Abstract

PURPOSE: To supply a front and a rear wheel cylinders with braking oil pressure approximate to an ideal distribution diagram, by causing a differential piston to slide together with a sleeve after the piston has slid by a set value.
CONSTITUTION: When there is a load on the vehicle and a shut-off valve V is open, the oil pressure Pm of a master cylinder remains applied to a second oil chamber R2. A stepped piston 41 slides right in comparison with the case of loading on the vehicle and pushes and moves the sleeve 40 right by a stepped part 41c according as the oil pressure Pm of the master cylinder rises. When the deceleration of ball 46 reaches a predetermined level, the ball 46 rolls forth and is seated on a valve seat 45. Therefore, the oil pressure Pm of the master cylinder and the oil pressure of a third oil chamber R3 rise. Then, the stepped piston 41 and the sleeve 40 are moved left together and the rear wheel cylinder oil pressure Pw of the seoncd oil chamber R2 increases according to the ideal distribution diagram.
