PUMP-ACCUMULATOR HYDRAULIC DRIVE Russian patent published in 2000 - IPC

Abstract RU 2159725 C1

FIELD: actuating mechanisms for control systems of various machines, ships, flying vehicles, etc. SUBSTANCE: proposed hydraulic drive is provided with two solenoid-operated valves for cross-connection of hydraulic pressure lines of both pumps and two check valves: one check valve is fitted in hydraulic pressure line of high-pressure pump; inlet of other check valve is connected with hydraulic pressure line of low-pressure pump and its outlet is connected with outlet of check valve fitted in hydraulic pressure line of high-pressure pump. EFFECT: extended functional capabilities of drive due to possibility of checking its functioning from auxiliary power source of limited power. 1 dwg
