Abstract:
1. A stop fill assembly for an enclosed tank, the assembly comprising: a port outside of the enclosed tank and in fluid communication with the inside of the tank and through which fluid flows into and out of the tank; a stop fill assembly in fluid communication with the port and through which fluid enters the tank and leaves the tank, the stop fill assembly moveable between a normally open configuration allowing fluid to enter and exit the tank and a closed configuration wherein the stop fill assembly prevents additional fluid from entering the tank when the fluid level in the tank reaches a full level during a filling operation in which fluid enters the tank through the port, the stop fill assembly including: a vertical shaft extending downwardly from the stop fill assembly inside the elongate support member, the vertical shaft having upper and lower ends, the upper end of the vertical shaft having a connection for connecting the vertical shaft to the lower shaft of the valve shuttle such that the valve shuttle rotates with the vertical shaft; and a float positioned in the tank remote from the elongate support member that moves in response to changes in fluid level in the tank and a float arm connected to the float, the float arm having proximate and distal end with the float being mounted on the distal end of the float arm away from the vertical shaft, the float arm operably engaged with the vertical shaft such that the float arm is rotatable around the lower end of the elongate support in response to changes in the fluid level in the tank and rotates the vertical shaft which rotates the lower shaft, shuttle body and upper shaft, moving the release rib into alignment with the release slot of the valve body when the fluid level in the tank reaches a full level such that pressure from fluid entering the tank forces the valve shuttle downward with the release rib translating longitudinally into the release slot allowing the shuttle body to close with the lower surface of the valve shuttle contacting the upper surface of the valve body and closing the space to block fluid from flowing through the fill port and entering the tank.
