ABSTRACT:
A vacuum release valve for use in a refrigerated compartment such as a domestic refrigerator which allows a small amount of outside air to enter the refrigerated compartment to prevent a vacuum from forming in the refrigerated compartment caused by warm air entering the compartment during door access into the compartment and then contracting by being cooled. The vacuum release valve includes a tubular valve body which penetrates through a floor of the compartment and a cap which is loosely captured to an end of the tubular body and which normally closes the tubular body but which can be lifted from the tubular body by a vacuum formed within the compartment.
