Refueling retainer
A refueling retainer comprises a body portion of a tubular shape inserted into and arranged at a fueling-side end portion of an inlet pipe through which fuel is introduced to a fuel tank. The body portion comprises at a leading end portion thereof: a tapered portion, which is an inner peripheral surface of the leading end portion inclined radially inward toward a leading end of the body portion; and a claw portion that projects from the leading end of the body portion in an inwardly bent manner.
1. A refueling retainer comprising:
a body portion of a tubular shape configured for insertion into an inlet pipe of a fuel tank through which fuel may be introduced, wherein the body portion is arranged at a fueling-side end portion of the inlet pipe,
wherein the body portion comprises a first component positioned on an upstream side and a second component positioned on a downstream side, and
wherein the second component comprises:
an upstream end portion that comprises a cylindrical cross-sectional shape and that is sized to mate with the first component;
a central portion that comprises a reduced diameter portion and an air vent hole;
a downstream end portion that includes:
an elliptical portion having an elliptical shape that is non-circular, wherein the elliptical shape has a major axis with a dimension D 1 and a minor axis with a dimension D 2 , wherein D 2 is sized to receive an outer diameter of a nozzle of a refueling gun for unleaded gasoline, and wherein D 2 is sized to reject an outer diameter of a nozzle of a refueling gun for leaded gasoline,
a tapered portion extending downstream from the elliptical portion,
a sensor cutout portion extending downstream from the elliptical portion and located below the tapered portion, and
a claw portion extending downstream and radially inwardly from the tapered portion;
wherein the claw portion includes first and second claws that bend inwardly toward each other and that extend from a downstream edge of the tapered portion, and
wherein the sensor cutout portion extends from a lower edge of the first claw to a lower edge of the second claw.
2. The refueling retainer according to claim 1 ,
wherein an inner circumference of the elliptical portion is configured such that the dimension D 2 of the minor axis is sized to be smaller than the outer diameter of the nozzle of a refueling gun for leaded gasoline.
3. The refueling retainer of claim 1 , wherein the first component and the second component are fixed together by a welded interface.
