Abstract
A housing having an interior, including: a) a pressure-compensation-device (PCD), for compensating a pressure in the interior as to surroundings of the housing, the interior being connected with the PCD, and an overpressure-valve (OV) with a lip-sealing-element (LSE) with a main-part and a flexible-sealing-lip (FSL), protruding radially-outwardly from an outer-circumference of the main-part and interacts with a sealing-surface (SS); b) an annular-channel (AC), between the main-part and SS, the FSL being in sealed contact with the SS with elastic-pretensioning in a sealing-position and sealingly closes the AC to prevent a flow-conducting connection between the interior/surroundings, and is lifted away from the SS in an open-position and opens the AC to provide a flow-conducting connection between the interior/surroundings; c) the FSL position between the sealing/open positions is controlled as a function of a pressure-difference between the pressure in the interior/surroundings, d) the main-part of the LSE has an inner-gas-through-channel (IGTC) connecting the interior/surroundings, e) the PCD includes a gas-permeable-membrane covering the IGTC, f) the OV and the membrane have a parallel connection, a pressure-difference between the interior/surroundings acting on the OV/membrane, having: g) the main-part and the FSL of the LSE are a single-piece elastomer, h) a borehole in a housing-wall, connectable with the interior/surroundings, i) the LSE is held in the borehole, the sealing-surface interacting with the FSL, and is formed by the radially-inner-circumferential-surface of the borehole.
