Abstract RU 2109111 C1

FIELD: road building and maintenance machinery and equipment. SUBSTANCE: hydraulically-operated brake system has hydraulic pump, hydraulic booster device which is connected with brake cylinders. Hydraulic booster device incorporates dual valve which isolates working space from delivery line and return line. Bore area of delivery valve is equal to surface area of upper rod and lower rod, and bore area of return valve is determined according to formula and it depends on bore area of delivery valve, force applied to upper rod, and pressure in working space. EFFECT: higher efficiency. 2 dwg
