This invention relates to a pressure balancing device for a container, preferably for a vehicle battery housing, comprising a housing having at least one inlet for gas, and at least one partially permeable valve element located downstream of the inlet in the direction of gas flow from the container. The valve element is located in a first position before at least one outlet and in a second position at least partially after the outlet. To improve pressure balancing, at least one sealing element is located in the region between the inlet and the valve element, the sealing element having at least one through-opening for gas. Gas can flow through the through-opening from either the inside or outside of the container. The permeable valve element, located downstream of the sealing element in the flow direction when viewed from inside the container, allows gas to flow in both directions. The invention also relates to a container and a vehicle.
