摘要
The invention relates to a protective housing (10) in explosion-protection-type pressure-proof encapsulation. Preferably at least one device (19, 36, 38, 39) for reducing explosive pressure is associated with the housing (10). The housing (10) comprises a first housing part (11) having a first sealing surface (13) and a second housing part (12) having a second sealing surface (14), wherein, when the housing (10) is in the closed pressure-proof state, a resilient seal (32) is held between the first sealing surface (13) and the second sealing surface (14) so as to be elastically deformed, and, as a result, closes the space (26) between the first sealing surface (13) and the second sealing surface (14) in a flame-proof manner in the event of an explosion inside the housing (10). The flame-proof arrangement according to the invention can replace a planar gap between, for example, a surface of a cover and a surface of a housing part, which gap requires conformity to relatively narrow manufacturing tolerances.
