SEALING MEMBRANE FOR SEALED FLUID STORAGE TANK Russian patent published in 2024 - IPC F17C3/02 F17C13/08 B63B25/16 

FIELD: machine building.

SUBSTANCE: group of inventions relates to a sealed reservoir for storing a fluid medium containing a sealing membrane. Sealing membrane comprises one metal plate (2). Metal plate (2) comprises flat section (3) forming the plane of the plate, and a plurality of projections (4) protruding from flat section (3) in a thickness direction perpendicular to the plane of the plate. Ledges (4) are spaced apart. Plate has one projection in all directions of the plane, wherein each projection (4) has base (5) forming a connection between projection (4) and flat section (3) and has one vertex (6). Base (5) has a first dimension and a second dimension in the plane formed by flat section (3). Distance between vertex (6) and base (5) in direction of thickness forms height (9) of projection. Height of projection (4) is from 8 to 20 mm. Each protrusion (4) is spaced from adjacent protrusion (4) in all directions of the plane at a distance less than or equal to two times the first size of base (5), and the ratio of the first size of base (5) to the height of protrusion (4) is less than or equal to 2.

EFFECT: reducing the risk of damage to the sealing membrane of a sealed reservoir from splashing while maintaining flexibility of the sealing membrane.
