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

FIELD: aviation; emergency systems.

SUBSTANCE: invention relates to passenger aircraft emergency systems. Power transmission unit of the hydraulic system of the aircraft contains pump (1) mechanically connected by a shaft to hydraulic motor (2), which is connected to the power supply of this system through flow limiter (3) and actuation valve (4). In its turn, pump (1) through throttle (5) is connected to first hydraulic cylinder (6) of the mechanism for controlling the characteristic working volume of the pump, which is connected by springs to rocker (7) and then to multi-position throttling distributor (8) of the regulator, which, taking into account the operation of flow limiter (3), comprises plunger (9) and is connected via throttle (10) to second hydraulic cylinder (11) to ensure required optimum power consumption of the pump at its control by hyperbolic relationship.

EFFECT: optimum power consumption of the pump.
