METHOD TO PROTECT VEHICLE HYDRAULIC SYSTEM FROM LOSSES OF WORKING LIQUID THROUGH BRAKE SYSTEM ELEMENTS Russian patent published in 2004 - IPC

FIELD: mechanical engineering; aircraft hydraulic systems.

SUBSTANCE: protection of vehicle hydraulic system from working liquid losses through brake system elements id provided by cutting off working liquid flow, in case of violation of tightness of brake system elements, by switching off electrohydraulic actuating device at a preset lapse of time from moment of deviation of tolerable actual brake pressure value from level set by operator. Switching off of electrohydraulic actuating device is done only when brake pressure changes at rate whose algebraic value does not exceed preset value.

EFFECT: improved operation reliability of vehicle owing to exclusion false operation of hydraulic system protection of low ambient temperature.
