ABSTRACT:
An valve assembly for automatically shutting off the flow of a pressurized liquid to a storage tank includes a cam that is rotated in response to the level of a liquid in the storage tank. A follower moves a poppet valve axially with a housing as a nonlinear function of rate of cam rotation. The poppet valve is moved to a closed position to terminate flow of a liquid to the storage tank whenever the liquid level within the storage tank reaches a predetermined level.
