Automatic truck tank fill system
First Claim
1. An automatic truck tank fill system comprising:
- a conduit adapted to be in fluid communication with a liquid supply source;
an electrically controlled valve in fluid communication with the conduit, the valve having a first open position and a second closed position;
a fill spout in fluid communication with the conduit, the fill spout comprising an outer chamber;
a controller in electrical communication with the valve, wherein a first signal opens the valve from a closed position, permitting fluid flow through the conduit, and wherein a second signal causes the valve to close, preventing fluid to flow through the conduit;
a tubing in fluid communication with the fill spout;
a pressure transducer in fluid communication with the tubing, the controller in electrical communication with the pressure transducer,wherein when a pressure in the tube reaches or exceeds an activation pressure (P1), the controller sends a signal to close the valve in the conduit;
a tubing breakaway connector placing the controller and the fill spout in releasable fluid communication; and
the controller positioned intermediate the tubing breakaway connector and the valve,wherein in operation of filling a truck tank, the tank includes air, the air in communication with the tubing and pressure transducer, the fill spout is in fluid communication with the tank and liquid fills the tank, air pressure increasing in the tank until the pressure reaches the activation pressure (P1) and the controller sends a signal to close the valve and stop the flow to the fluid supply.

Abstract
An automatic truck tank fill system includes a conduit in fluid communication with a fluid supply source. An electrically controlled valve is in fluid communication with the conduit. A fill spout is in fluid communication with the conduit, the fill spout including an outer chamber. A controller is in electrical communication with the valve. A first signal opens the valve from a closed position permitting fluid flow through the conduit, and a second signal causes the valve to close, preventing fluid to flow through the conduit. A tubing is in fluid communication with the fill spout. A pressure transducer is in fluid communication with the tubing, and the controller is in electrical communication with the pressure transducer. When a pressure in the tube reaches or exceeds an activation pressure (P1), the controller sends a signal to close the valve in the conduit.

6. An automatic truck tank fill system comprising;
-
a pipe in fluid communication with a liquid supply source; a flexible hose detachably in fluid communication with the pipe; a valve defined in the pipe; a fill spout in fluid communication with the hose, the fill spout comprising an outer chamber; an air pressure sensor in communication with the controller and the tank; a controller having a start control and stop control, the controller in fluid communication with the fill spout by a tubing and the controller in electrical communication with the valve, wherein the controller causes the valve to open when the start control is activated, and wherein the controller causes the valve to close when an air pressure in the truck tank reaches or exceeds an activation pressure (P1) or the stop control is activated; and the controller is positioned intermediate the valve and the flexible hose, wherein during the filling operation of the tank as liquid is flowing into the tank, air is in the tank and as the tank fills the air pressure will increase until it reaches the activation pressure (P1).
