Abstract

PURPOSE: To assure the change-over operation of change-over valves of hydraulic circuits and raise the safety, by using open/close valves as all the change-over valves.
CONSTITUTION: In the initial stage of braking, oil pressure from a master cylinder 12 is transmitted to a wheel cylinder 24 through both a normally open valve 20 and an orifice 28 to sharply raise the pressure in the wheel cylinder. When a wheel has reached a state just before locking-up, the reaching is detected by a detector 32 to open a normally closed valve 30. As a result, oil pressure in a second oil passage 22 is transmitted to a third oil passage 46 and a fourth oil passage 50 to actuate a plurality of return pumps 52 of different phase and reaches a fifth oil passage 56. The oil in the each pump 52 is introduced into the fifth oil passage 56 by the action of teeth of a cam 66 to displace a valve member in the valve 20 to close it. Oil is supplied only through an auxiliary operating oil passage 26 to reduce the oil pressure in the wheel cylinder 24.
