초록

An apparatus (10 or 10a) for use in venting a compartment of a vehicle includes valve elements (14 and 16 or 14a and 16a). A biasing spring (130 or 130a) is effective to urge one of the valve elements toward a closed condition. A spring connection (134 or 236) is effective to transmit torque urging the one valve element (16 or 16a) toward a closed condition. Another valve element (14) may overlie the one valve element (16). Alternatively, the valve elements (14a and 16a) may be spaced from each other.
