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

FIELD: aircraft emergency systems.

SUBSTANCE: aircraft hydraulic system power transfer unit comprises pump (1) connected mechanically by shaft to hydraulic motor (2). First (3) and second (4) hydraulic cylinders of the mechanism for controlling the characteristic working volume of hydraulic motor (2). First hydraulic cylinder (3) through a fixed throttle, and the second hydraulic cylinder (4) through a multi-position three-line spring-loaded hydraulic control valve (5). Position of hydraulic control valve (5) is determined by difference in pressure on throttle (6) installed in the delivery pump line. Pressure before and after throttle (6) is compared on spool of hydraulic control valve (5).

EFFECT: optimum power consumption of the hydraulic motor is achieved.
