HYDRAULIC TANK OF HYDRAULIC CONTROL SYSTEM OF AIRCRAFT Russian patent published in 2016 - IPC B64C13/42 

FIELD: aviation.

SUBSTANCE: invention relates to aircraft engineering, particularly to hydraulic systems of aircraft. Hydraulic tank of hydraulic aircraft control system comprises a blown working chamber without separating working fluid and gas and an antigravity chamber, separated by a partition and linked by a foam removal channel with a weight check valve and free overflow channel, as well as connection for pressurisation of working chamber, anti-foaming agent, and connections for supply and discharge of working fluid linked with upper part of antigravity chamber. Defoamer includes convergent conical tip mounted on facing in antigravity chamber inlet opening for supply of hydraulic fluid, and a conical diffuser tip mounted on facing in antigravity chamber outlet nozzle hole for discharging working fluid.

EFFECT: higher reliability of hydraulic system by preventing entry of foam into hydraulic drives.
