Abstract
A bi-directional vent and overpressure relief valve is disclosed including a housing enclosing a regulator member. The regulator member is biased into contact with a wall of the housing to prevent flow of gasses through the housing. A centrally located diaphragm on the regulator provides a venting function for permitting gasses to flow in either direction through the housing when predetermined minimum pressure differentials are produced across the housing. In addition, the regulator is adapted to move out of contact with the housing in the event that an overpressure condition exists in order to provide a pressure relief function permitting a high flow of gases through the housing.
