DEVICE OF HYDRAULIC SYSTEM OF SMALL HYDRAULIC UNIT AND METHOD OF ITS APPLICATION Russian patent published in 2023 - IPC B64F5/60 F15B19/00 

FIELD: aircraft equipment.

SUBSTANCE: design of the hydraulic system of a small-sized hydraulic installation includes an electric drive pump connected by the input to the suction line of the working fluid from tank (1) of the hydraulic system of the aircraft, and by the output to the supply line of the working fluid into tank (1) of the hydraulic system of the aircraft. The working fluid suction line includes working fluid suction hose (2), working fluid temperature control system (4) located in front of heat exchanger (5), and heat exchanger (5), including an internal reservoir for working fluid, is connected to the inlet of electric drive pump (6). The working fluid injection line includes working fluid purification filter (9), pressure gauge (10), at least one working fluid injection hose (12), safety valve (8), wherein safety valve (8) is installed at the outlet of electric drive pump (6).

EFFECT: autonomous testing of operability of the hydraulic system of an aircraft is achieved while increasing safety of operation of a small-sized hydraulic installation with an increase in the time of its continuous operation.
