ABSTRACT:
A tank pressure and vacuum relief mechanism for relieving excess pressure or vacuum in a tank interior. The mechanism includes a housing disposed in a wall of the tank, such housing containing a one-way, normally-closed pressure relief valve for venting excessive pressure in the tank to the atmosphere. The housing also contains a one-way, normally-closed vacuum relief valve for admitting atmospheric pressure to the tank interior to relieve excessive vacuum therein. The mechanism seals completely on tank roll-over at any angle to prevent tank product leakage.
