Abstract
PURPOSE: To make it possible to construct and assemble a hydraulic pressure control system and to control the braking pressures of the respective system by providing first cut-valve means, second cut-valve means, pressure reducing means and a servo- mechanism.
CONSTITUTION: First and second cut valve means 16 and 17 are mounted in a hydraulic circuit form a master cylinder 11 to the brake cylinder of rear wheels 13 and 15 and are controlled by pressure reducing means. This means is composed of a first pressure reducing piston 18, a first pressure reducing chamber 19, a second pressure reducing chamber 21 and a second pressure reducing piston 20. The second piston 20 has its one end exposed to a hydraulic pressure passage 22 extending from the second valve 17 and the rear wheel 15 and operated by the differential pressure between the cut-valves 16 and 17 and the rear wheels 13 and 15. On the other hand, a power piston 23 divides a casing 24 into a constant pressure chamber 26 having always communication with a vacuum source 25 and a variable pressure chamber 27 having its connection interchanged with the vacuum source 25 and the atmosphere in accordance with the conduction and incoduction of an electromagnetic valve 28.
