TELESCOPIC AIR DUCT FOR ANTI-ICING SYSTEM OF SLATS Russian patent published in 2022 - IPC F16L27/12 B64D15/04 

FIELD: means for connecting pipelines.

SUBSTANCE: invention relates to means for connecting pipelines, allowing their longitudinal adjustment or movement. Telescopic air duct of anti-icing system of slats, containing outer and inner sliding cylinders with sealing devices and assemblies for connection to connected pipelines, an intermediate cylinder is additionally introduced, and sealing devices are located between the interacting surfaces of the outer and intermediate cylinders and intermediate and inner cylinders. Each of the attachment nodes has a rotation compensator, including a male sphere and a female part, while the male spheres of the attachment nodes are made in one piece with the corresponding outer and inner cylinders. The intermediate and inner cylinders are equipped with end sealing - centering rings, interacting, respectively, with the inner surface of the outer cylinder and the inner surface of the intermediate cylinder.

EFFECT: invention provides an increase in the operational characteristics of the connecting pipeline, as well as an expansion of the range of movements of the connected pipelines.
