<p>976,871. Fuel systems. T. RACZ. Dec. 12, 1960 [Dec. 12, 1959], No. 42762/60. Heading FIB. [Also in Division B2] In liquid fuel system, the quantity of fuel passing through a centrifugal separator is controlled by the fuel consumption. Fuel is pumped from a tank 1 through a restrictor 10, the pressure drop across which is inversely proportional to the level of fuel in a tank 2. The fuel passing through the restrictor is discharged through an elbow 11, falls down a conduit 30 to a heater 31, and passes through centrifuges 32, 33 before entering a tank 34 connected to the tank 2. Fuel from the tank 34 is pumped through a heater 41 to the distributer 43 leading to fuel pumps 45 on an engine 3, surplus fuel being returned to the tank 34. If more or less fuel than is necessary reaches the distributer, the level in the tanks 34, 2 rises or falls so that the pressure drop over the restrictor decreases or increases so that the quantity of fuel passing through the centrifuges is dependent on fuel consumption. Instead of the pressure drop across the restrictor being dependent on the level in the tanks 34, 2 only, it may also be dependent on the setting of the pump control.</p> |
