VEHICLE ANTILOCKING BRAKE SYSTEM Russian patent published in 1998 - IPC

FIELD: transport engineering. SUBSTANCE: quick-acting valve providing rise and drop of liquid pressure at braking is introduced into hydraulic drive of antilocking brake system. Drilled holes are made in quick-acting valve body to form drain and control lines. Chambers are made in body to accommodate coaxially arranged control rod, slider with plunger, shutoff valve with piston in which throttling hole is made. All above-indicated parts are spring loaded. System provide pulsating movement of liquid in control line, and rise and drop of pressure in hydraulic drive and brake operating cylinders, thus providing pulse braking. EFFECT: enhanced reliability of brake system. 3 dwg
