METHOD TO PROTECT VEHICLE HYDRAULIC SYSTEM FROM WORKING LIQUID LOSSES THROUGH BRAKE SYSTEM MEMBERS Russian patent published in 1999 - IPC

FIELD: mechanical engineering; hydraulic systems of aircraft. SUBSTANCE: proposed method is aimed at prevention of failure of hydraulic system in case of violation of tightness of pipeline or members of brake system on any section from slave device to wheel brake. This is provided by cutting out pressure control electrohydraulic slave device at violation of tightness of brake system with resulting cutting off of working liquid flow. Cutting out is provided at a lapse of preset delay time from moment when relative deviation of measured value of actual brake pressure from measured value of pressure level preset by operator exceeds tolerable value. EFFECT: enhanced operation reliability of vehicle. 1 dwg
