Title: EXPLOSION-PROOF HOUSING WITH INNER PRESSURE RELIEF
Abstract:
The invention relates to a housing arrangement (10) comprising an inner space (16) for accommodating components (13, 14, 15) which can form sources of ignition. The housing arrangement (10) further comprises a part housing (12) which is arranged in or on the housing (11) and the interior space (17) of which acts as a pressure relief volume (22). The two interior spaces (16, 17) are connected together via a passage (18) in which a gas-permeable and flame-arresting arrangement (19) is provided. This can be formed from a porous body (20), for instance, which is gas permeable and acts in a throttling and cooling manner on a gas flow passing through it.
