Abstract: 952,956. Filling tanks. J. H. DE FREES. March 28, 1962, No. 11837/62. Heading B8T. [Also in Divisions F2 and G3] Liquid flow control means for an inlet port 25b, Fig. 3, in a tank wall 63 comprises a cylindrical housing 25, a main valve 65 spring biased to closed position, first, second, third and fourth outlet means from the housing, an axial opening through the main valve and a tube 84 extending from the opening to form an annular pressure chamber 97 into which the main valve is movable by the pressure of liquid entering the tank to clear the first outlet 76, a second valve 87 spring- biased to closing position across the inner end of the tube 84 and defining a second pressure chamber 100, the valve 87 being movable by the pressure of liquid entering the tank to clear the second outlet 95, a first pipe (not shown) having a discharge end at an elevated level to vent the chamber 97, a second pipe 57 to vent the chamber 100 at an elevated level, a first duct 96 to permit liquid to flow from tube 84 into the chamber 97 and thence through the first pipe, a second duct 99 to permit liquid to flow from the tube 84 into the chamber 100 and thence through the pipe 57, liquid level responsive means 54 for closing the first pipe to create a pressure in the chamber 97 and close the valve 65, and similar means for closing the pipe 57 to create a pressure in the chamber 100 and close the second valve 87. The third and fourth outlets are formed by the first and second pipes which are controlled by the liquid level responsive means each of which consists of a float, such as 104, Fig. 5, secured to a hollow member 103 carrying a valve 106 to engage a seat 109. The flow control means may be fitted in each of three compartments A, B and C of a trailer tank 22 for the transportation of liquid, such as gasoline. Piping 26 and a manually-controlled valve 28 connect each means to a manifold 27 having an inlet pipe 29 and a discharge pipe 30 controlled by a valve 31 while a second manifold 44 fitted with selector valves 45 permits a hand pump 42 to be connected with a space 70 of one of the control means to lift the valve 65 of a compartment to be discharged. A bleed hole 110 in the valve 106 prevents excessive resistance to the pump action. When the trailer is in transit, closure of a door 47 causes a valve 48 to connect the manifold to atmosphere so that the spaces 70 cannot become pressurised. The same purpose can also be achieved by a frangible plug or valve 53 near the driver's cab. A second door 38 also controls a valve 37 which couples an air supply, such as that for the brakes, to venting valves 34 in the compartments. In a modification of the flow control means, the valve 87 is replaced by a piston valve having a control duct to replace the duct 99. After the valve controlled by the means 54 has closed flow into the compartment being loaded is reduced from over 1000 gallons per minute to about 50 gallons per minute.
