BODY WITH EMBEDDED PRESSURE RELIEF APPARATUS Russian patent published in 2021 - IPC A62C4/00 H02B1/28 

FIELD: engineering.

SUBSTANCE: housing (10) according to the invention has at least one pressure relief body (15) located in the pressure equalising hole (14) of one of the parts (12, 13) of the housing. To fix the pressure relief body (15), a thickened area (20) is provided in or on the part (12) of the housing, respectively, overlapping with the edge zone of the pressure relief body (15) along the entire peripheral surface (23) of the pressure relief body (15) on both flat sides (16, 17) of the pressure relief body (15). The resulting penetration depth S1, wherein said depth should be measured parallel to the flat sides (16, 17), is preferably greater than the thickness D1, D2 of the part of the thickened area (20) overlapping with the edge zone (24). The pressure relief body (15) consists of sintered wire fabric.

EFFECT: described complex of measures allows achieving both a microscopic and a macroscopic form fit connection between the pressure relief body (15) and the part (12) of the housing; the connection remains stable in the long term and is pressure-resistant in a wide temperature range.
