Abstract
A tank pressure control valve is provided for controlling the discharge of fuel vapor from a fuel tank. In one embodiment, the tank pressure control valve is configured to use pressurized fuel vapor to control a flexible diaphragm operable between a closed position blocking discharge of fuel vapor from the fuel tank and an opened position allowing such discharge. In another embodiment, the tank pressure control valve is configured to use pressurized fuel vapor to move a flexible diaphragm to move a rigid valve member between a closed position and an opened position.
