from The Century Dictionary.

  • noun A device in which the flow or feed of a liquid is controlled by the rise and fall of a float: specifically, a device for carburetting an air-current in motor-cars, or in internal-combustion engines, in which the rising of the level of the liquid gasoline raises a valve to close the flow from the inlet, and a lowering of the level opens the flow again. Much used in modern motor-cars.
