Abstract

PURPOSE: To simplify structure, reduce number of components, and to reduce cost by allowing the direction of the spring force of a control spring of an independent two system type liquid controller and the direction of action of the hydraulic force to a control piston to be opposed each other and allowing only one control spring to be used in common.
CONSTITUTION: When control hydraulic pressure is transmitted from master cylinder to both input ports 16 in braking, the hydraulic pressure is transmitted from each port 17, 18 to the front and rear wheel brake apparatuses through input and output liquid chambers a and b. At this time, the hydraulic force which spreads each control piston 9, due to the relation between the areas of pressure reception, rightward and leftward against the spring force of a control spring 10 acts onto each piston 9. When the amount of spreading reaches a prescribed value, each valve body 12 contacts with a valve seat 6, and the communication between both chambers a and b is cut-off. When the liquid pressure in the chamber a increases, and the hydraulic force in the direction of spreading of the piston 9 decreases, the valve body part 12 is separated from the valve seat 6, and the both chambers a and b are allowed to communicate, again and effective control is permitted.
