Abstract
An apparatus for use in venting a compartment in a vehicle includes a housing which at least partially defines an air flow passage. A valve element moves from a closed condition to an open condition to enable air to flow through the air flow passage. The valve element has an inner surface facing the air flow passage when the valve element is in the closed condition. The valve element has an outer surface opposite the inner surface facing away from the air flow passage when the valve element is in the closed condition. A spring wire deflects as the valve element moves from the closed condition toward the open condition and is effective to urge the valve element toward the closed condition. The spring wire extends in a straight line from the housing to the inner surface of the valve element when the valve element is in the closed condition.
