Abstract
An inwardly opening mechanical vent system is provided for use in a fluid tank having a bottom loading valve and a vent formed in an upper tank surface. The vent system includes a spring interposed between a vent valve and a body extending downwardly into the tank to bias the vent valve upwardly into a closed position. A shaft extends downwardly from the vent valve and is connected to a lever mechanism. The lever mechanism includes a scissor-hinge assembly connected to a trunnion of the body. A linkage rod extends upwardly from the bottom loading valve and is capable of actuating the lever mechanism to lower the shaft and vent valve into the tank to open the vent when the bottom loading valve is opened.
