FIELD: transport engineering. SUBSTANCE: in case of pressure drop below tolerable limit caused by violation of tightness in any circuit, pressure pickups energize electromagnetic hydraulic valves 16-19 through switching unit 15 and these valves cut off defective circuits from master cylinders 1, 2, thus preventing pressure drop in entire brake system. EFFECT: enhanced reliability of operation. 1 cl, 1 dwg |
