Abstract
In a gasoline or like tank truck, a roll over valve is provided which permits opening of the emergency valve of the tank truck without opening the vent valve. The roll over valve is incorporated in the air lines extending between the source of compressed air and the emergency valve. The roll over valve includes a valve closure member movable between a first position in which the emergency valve is activated by the same air pressure source as the vent valve and a second position in which the emergency valve is adapted to be activated by an independent source of air without permitting the independent source to activate the vent valve.
