FIELD: aircraft engineering.
SUBSTANCE: claimed device comprises fluid pump with self-contained drive and hydraulic tank with shutoff device. Said shutoff device is composed by two-position four-way hydraulic pressure control valve with flow channels. Said shutoff device at first position communicates the ground hydraulic plant hydraulic tank with vacuum pump arranged at its top section with fluid pump suction line and with unions for connection to suction line of attended hydraulic system. Said shutoff device at second position communicates fluid pump suction line with the union for connection to the line of attended hydraulic system. Source of vibration is rigidly secured to hydraulic tank outer wall.
EFFECT: higher efficiency of air removal from working fluid.
