SEALING STRUCTURE Russian patent published in 2019 - IPC F16J15/10 

FIELD: construction.

SUBSTANCE: sealing structure comprising a first housing defining a first surface and a second housing defining a second surface, a recess extending into the second housing from the second surface and defining a recess opening on the second surface, and a retaining structure projecting partially through said recess with at least a predetermined recess opening. Elastic sealing body is arranged inside recess, wherein retaining structure retains resilient sealing body inside recess and the resilient sealing body forms a fluid seal between the first housing and the second housing when the resilient sealing body is brought into the clamping interaction with both the first surface and the recess. Second housing includes a first material with a first coefficient of thermal expansion and a second material with a second coefficient of thermal expansion, which is different from the first thermal expansion coefficient, wherein the recess is defined or limited by both the first material and the second material.

EFFECT: invention relates to a sealing structure.
