Pressure relieving device for pressure-tight encapsulated housing

摘要

Pressure relieving device (18) for a protective housing (10) for the pressure-resistant encapsulation of resources, the ignition sources can form,with a receiving member (19), which has a passage (20),with a porous body (23), which in the passage (20) is arranged pointing away from one another and two exposed surfaces (26, 27) and a rim (28) comprises,the body (23) at its edge (28) with a sealing pores (31) is provided, in that the porous body having a mounting edge is gripped, which applies such a high clamping pressure, that the pores of the porous body in the range of action of the mounting edge collapse, as a result of which the sealing pores is given.
