Pressure Release Device For Housings With Flameproof Encapsulation Comprising A Porous Body Comprising Interference Fit
Abstract: An accommodating body (18), which is equipped to accommodate a porous body (24) in a passage (22) of the accommodating body (18), is provided for the pressure release device (12) according to the invention. A provided porous body (24) is arranged in the passage (22). The porous body (24) is elastically deformed to a certain extent by means of an interference fit in the passage (22). The porous body (24) is thus supported against a mating surface (34) of the accommodating body (18) along its periphery and is thereby held securely in the passage (22). The arrangement is closed in terms of the ignition protection type flameproof enclosure by the positive abutting of the porous body (24) on the mating surface (34) along its periphery.
