CONTROLLED POWER TRANSMISSION UNIT OF AIRCRAFT HYDRAULIC SYSTEM Russian patent published in 2024 - IPC B64C25/22 B64C25/30 F15B15/18 

FIELD: aircraft engineering.

SUBSTANCE: invention relates to aircraft engineering and can be used in civil aircraft emergency systems. Adjustable power transmission unit of aircraft hydraulic system comprises hydraulic motor (3), check valve (4), throttle (5). Hydraulic motor (3) is connected by common shaft (2) with pump (1), and throttle (5) converts pressure in discharge line of pump (1) at change of actual load on actuating hydraulic motors into pressure of control of multi-position throttling hydraulic control valve (6). Multi-position throttling hydraulic control valve (6) is connected to hydraulic cylinder (7) of control mechanism of characteristic working volume of pump with possibility of proportional supply of working fluid to hydraulic cylinder to compensate for pressure change in the system behind the pump and providing required speed of actuating hydraulic motors.

EFFECT: reduced probability of error during determination of emergency mode of system operation.
