Patent ID: 8047223

Claim:
A stop fill assembly for an enclosed tank, the stop fill assembly comprising: a port accessible from outside the tank, the port allowing fluid to be moved in and out of the tank; a shaft that rotates according to a change in fluid level within the tank; a stop-fill valve assembly for transitioning between an open configuration and a closed configuration based on the rotational position of the shaft, the stop-fill valve assembly including: a valve shuttle that is rotationally engaged with, but longitudinally independently movable from the shaft to translate longitudinally independent of the shaft to move between an open position corresponding with the open configuration and the closed position as the shaft rotates; the stop-fill valve assembly including a valve body having a release slot, wherein the valve shuttle has a release rib that does not engage the release slot when the stop-fill assembly is in the open configuration, but translates longitudinally into the release slot when the valve shuttle rotates into the closed position and the stop-fill valve assembly is in the closed configuration; and a float positioned in the tank that moves in response to changes in fluid level in the tank and a float arm connected to the float, the float arm having a proximate and distal end, wherein the float is mounted on the distal end of the float arm away from the shaft, the proximate end of float arm engaged with the shaft such that the float arm rotates the shaft in response to changes in the fluid level in the tank.
