Abstract
A portable pre-filtering fuel filler device is described herein. The portable pre-filtering fuel filler device includes a fuel inlet opening, an interior fuel conduit in fluidic communication with the fuel inlet opening, and a water chamber positioned vertically below the interior fuel conduit. The portable pre-filtering fuel filler device further includes a fuel filter in fluidic communication with the water chamber and positioned vertically above the water chamber and a fuel outlet opening in fluidic communication with the fuel filter.
Claims21
A portable pre-filtering fuel filler device comprising:
- a fuel inlet opening;
- an interior fuel conduit in fluidic communication with the fuel inlet opening;
- a water chamber positioned vertically below the interior fuel conduit;
- a fuel filter in fluidic communication with the water chamber and positioned vertically above the water chamber;
- a fuel outlet opening in fluidic communication with the fuel filter;
- an upper wall physically coupled to a portion of the interior fuel conduit below the fuel filter, where the upper wall extends radially outward and downwardly from the interior fuel conduit toward the water chamber defining a fuel vapor flow path, and where the upper wall is located between the fuel filter and the water chamber with a bottom surface of the upper wall facing the water chamber and a coaleser and a top surface of the upper wall facing the fuel filter;
- and
- a gap located between side surfaces of the upper wall and a housing of the fuel filler device, where the side surfaces force fuel vapor to turn around before flowing to the fuel filter.
5 more elements
A system comprising:
- a portable pre-filtering fuel filler device including:
- a fuel inlet opening;
- an interior fuel conduit positioned downstream of the fuel inlet opening;
- a coaleser positioned directly downstream of an end of the interior fuel conduit adjacent to a bottom surface of an upper wall;
- a water chamber positioned vertically below the interior fuel conduit;
- a fuel filter positioned downstream of the interior fuel conduit and vertically above the water chamber;
- the upper wall is physically coupled to a portion of the interior fuel conduit extending below the fuel filter, where the upper wall defines a flow path of the interior fuel conduit to the coaleser by being spaced away from the fuel filter and extending radially outward before extending downward to the water chamber, and where the upper wall is located between the fuel filter and water chamber, where the bottom surface of the upper wall faces the water chamber and the coaleser and a top surface of the upper wall faces the fuel filter, the upper wall further comprising side surfaces radially spaced away from a housing of the portable device;
- and
- a fuel outlet opening positioned downstream of the fuel filter;
- and
- a vehicle having a vehicle fuel tank filling inlet shaped to receive a portion of the portable device.
8 more elements
A portable pre-filtering fuel filler device comprising:
- a fuel inlet opening;
- an interior fuel conduit positioned directly downstream of the fuel inlet opening;
- a coaleser positioned directly downstream of an end of the interior fuel conduit and configured to separate water from a fuel mixture exiting the interior fuel conduit;
- a water chamber positioned vertically below the interior fuel conduit;
- a fuel filter positioned downstream of the interior fuel conduit and vertically above the water chamber;
- an upper wall spaced away from the fuel filter, the upper wall physically coupled to and extending radially outward from a portion of the interior fuel conduit vertically below the fuel filter, and where the upper wall extends downward toward the water chamber at a portion of the upper wall nearest to a housing of the portable device, the upper wall further comprising a bottom surface facing the water chamber and the coaleser, a top surface facing the fuel filter and the interior fuel conduit, and a side surface facing the housing, and where the housing is radially spaced away from the upper wall such that fuel vapor turns around before flowing to the fuel filter from the interior fuel conduit;
- and
- a filler nozzle including a fuel outlet opening and positioned downstream of the fuel filter, vertically above the water chamber, and vertically below the fuel inlet opening.
