DEVICE FOR DISSOLVED IN OPERATING FLUID AIR REMOVAL FROM HYDRAULIC SYSTEMS OF CLOSED-TYPE AIRCRAFTS

摘要

FIELD: transportation. ^ SUBSTANCE: device contains hydraulic pump with independent drive connected with pressure line, suction line and nozzles for connecting to board valves of delivery and suction pipes of hydraulic system being serviced. The device also contains hydraulic tank with shut off device made as two-position four-way distribution valve with flowing channels. The channels connect in the first position - hydraulic tank with suction line of hydraulic pump and nozzles for connecting to suction pipes of serviced hydraulic system, and in the second position - suction line of hydraulic pump with nozzle for connecting to pipes of serviced hydraulic system. In the upper part of ground hydraulic unit hydraulic tank vacuum pump is installed. ^ EFFECT: increase in effectiveness of dissolved in operating fluid air removal from hydraulic system of aircraft. ^ 1 dwg
