A degassing unit to be connected fluid-tightly to a pressure compensation opening of an electronics housing has a base body with gas passage opening. A semipermeable membrane, fastened fluid-tightly to a membrane carrier, allows gaseous media to pass from an environment into the electronics housing and in reverse but prevents passage of liquid media and solids. In normal operation, the membrane covers the gas passage opening. An axial seal circumferentially extends about the gas passage opening. The membrane carrier is moveable relative to the base body and, in normal operation, is pressed by axial force seal-tightly against the axial seal. The membrane carrier, when a predetermined pressure difference between housing interior and environment is surpassed, lifts off the base body to release an emergency degassing opening surrounding the membrane. The axial seal is a lip seal and made of a material softer than a material of the membrane carrier.

This invention is a vent valve suitable for an electric storage battery in which a movable valve member 16 co-operating with a valve seat 14 is caused to move by being attached to or integral with a rubber annulus 19 one side of which is exposed to ambient pressure while the other side is exposed to the pressure within the battery. The area of the annulus 19 is substantial compared with the size of the valve member so that a small pressure difference across it can be sufficient to open the vent. Alternatively (Fig. 7) a corrugated annulus 19 may be provided which forms a seal with a post 42 depending from a closure 23. Motion of the annulus under influence of pressure causes the inner edge to encounter recesses 43, allowing escape of gas past the annulus. In a further embodiment (Fig. 9) a flexible disc 19 seals against shoulder 116 and unseals when the disc 19 distorts under the influence of pressure. <IMAGE>
