ABSTRACT:
This invention relates to a tap assembly for a liquid vessel, having an overfill protection device and a float controlled mechanical or magnetic level gauge. A single float actuates a stem of the overfill protection device as well as a rod of the level gauge. The rod of the level gauge has one end movable linearly in a valve body bore and carrying a permanent magnet for actuating a magnetic level indicator. In one embodiment a crank mechanism may be provided between a float lever and the rod of the level gauge to cause the rod to effectuate a swinging movement and simultaneously displace the rod longitudinally to cause linear displacement of the permanent magnet in the valve body bore. In another embodiment the rod may be actuated by a cam to cause axial displacement thereof without swinging motion.
