HYDRAULIC SHIMMY DAMPER FOR AIRCRAFT LANDING GEAR Russian patent published in 2014 - IPC B64C25/58 F16F9/18 F16F9/342 F16F9/44 

FIELD: machine building.

SUBSTANCE: damper comprises hollow housing (10), cylinder piston (20) with the piston head, which forms two active hydraulic cameras, rod and deflecting units. A hydraulic compensator (40) is made with the internal volume of fluid medium, which is much greater than the volume of fluid medium removed from the housing. A hydraulic manifold (30) is located between the housing and hydraulic compensator. The control manifold is connected to the hydraulic compensator and establishes the passage between cameras. Manifold contains the interchangeable hydraulic valves (CV1, RV1; CV2, RV2) of the cartridge type for throttling of fluid medium flowing from cameras into the passage, allowing fluid medium to flow freely into cameras from the passage.

EFFECT: decrease of sensitivity to variations of oil temperature, absence of cavitation, simplification of damper adjustment.
