Document Type and Number:
Japanese Patent JPS61108044
Kind Code:
A
Abstract:
PURPOSE:To obtain a small-sized hydraulic pump driven by a hydraulic motor by switching cut valves installed into a feeding conduit to the cut position by the pressure discharged from the hydraulic pump. CONSTITUTION:When a wheel is locked, a control valve 11 is switched to the second position. Then, a hydraulic motor 10 is driven by the pressurized oil supplied from the pump 12, and pumps 8 and 9 start operation. Cut valves 101-104 are switched to the second position by the oil discharged from the pumps 8 and 9, and brake pipes 21, 22, 31, and 32 are cut-off. Then, the selector valve corresponding to the wheel cylinder for the locked wheel among the selector valves 106-109 is switched to the second position, and the wheel cylinder communicates to a reservoir 11. Therefore, the brake pressure is reduced. When the revolution of the wheel is restored, the above-described selector valve is switched to the first position, and brake oil is supplied slowly into the wheel cylinder through the branched pipes 71, 72, 81, and 82 having large flow-passage resistance, and the pressure is increased gradually.
