Abstract
A fuel tank cap includes a housing having a side wall, a bottom wall, and a receptacle, a fuel vapor adsorption material positioned within the receptacle, an inlet at least partially defined by the bottom wall and configured to provide fluid communication with a fuel tank vapor space, an outlet at least partially defined by the bottom wall and configured to provide fluid communication with the atmosphere, an internal wall extending from the bottom wall at least partially into the receptacle, and an aperture at least partially defined by the internal wall and configured to permit fuel vapor to flow in a vapor flow path from one side of the internal wall to the other side of the internal wall.
Claims25
A fuel tank cap comprising:
- a housing having a side wall, a bottom wall, and a receptacle;
- a fuel vapor adsorption material positioned within the receptacle;
- an inlet at least partially defined by the bottom wall and configured to provide fluid communication with a fuel tank vapor space;
- an outlet at least partially defined by the bottom wall and configured to provide fluid communication with the atmosphere;
- an internal wall extending from the bottom wall at least partially into the receptacle;
- and
- an aperture at least partially defined by the internal wall and configured to permit fuel vapor to flow in a vapor flow path from one side of the internal wall to the other side of the internal wall.
A fuel tank cap for use with a fuel tank having a fuel inlet, the fuel tank cap comprising:
- a sealing portion configured to engage the fuel inlet for sealing the fuel inlet;
- a bottom wall horizontally disposed above the sealing portion when the fuel tank cap is installed on the fuel tank;
- a receptacle at least partially defined by the bottom wall and containing therein a fuel vapor adsorption material;
- a vertically oriented internal wall in contact with the bottom wall and dividing the receptacle into a first region and a second region;
- an inlet to the receptacle for allowing fuel vapor from the fuel tank to enter the receptacle;
- and
- an outlet from the receptacle for allowing scrubbed fuel vapor to exit the receptacle;
- wherein the internal wall intersects a direct line extending between the inlet and the outlet.
