Abstract
The valve for pressure compensation and/or for emergency venting of a container, preferably of a housing of a vehicle battery, has a housing (6) with an inlet (6a) that is closable by at least one valve element (23) subjected to a closing force in a first position. The housing (6) is at least partially gas-permeable and preferably water-tight, and has at least one outlet (26) which is located behind the valve element (23) when the valve element (23) assumes its first position. So that in case of a malfunction even larger quantities of gas can be guided to the exterior through the valve, is the valve element for an increased pressure surpassing the closing force at the inlet (6a) is adjustable in the direction toward a second position against the closing force, in which the valve element (23) at least partially opens the outlet (26) such that the outlet (26) is directly connected in flow communication with the inlet (6a).
