Patent ID: 8534316

Claim:
A reservoir structure of a fuel delivery structure for a diesel vehicle, the reservoir structure including: a fuel reservoir having a bottom surface, a primary fill opening in the bottom surface for permitting fuel to pass from a fuel tank of the vehicle into the reservoir, a secondary fill opening in the reservoir that is elevated from the bottom surface, the secondary fill opening communicating the fuel tank with the reservoir for permitting fuel to pass from the fuel tank directly into the reservoir, a first valve member associated with the primary fill opening constructed and arranged to close the primary fill opening under certain pressure conditions in the reservoir and, under pressure conditions in the reservoir different from the certain pressure conditions, to permit fuel to enter the reservoir through the primary fill opening, and a second valve member associated with the secondary fill opening constructed and arranged to close the secondary fill opening under certain pressure conditions in the reservoir and, under pressure conditions in the reservoir different from the certain pressure conditions, to permit fuel to enter the reservoir through the secondary fill opening in the event the primary opening is substantially blocked, wherein the reservoir structure is in combination with a suction tube in the reservoir, the suction tube being constructed and arranged to be coupled with a suction unit to draw fuel under certain conditions into the reservoir via the first fill opening and, when the first fill opening is substantially blocked, via the secondary fill opening; and in further combination with a fuel tank, the reservoir resting on a bottom surface of the fuel tank; wherein the secondary fill opening and a bottom opening of the suction tube are generally at the same height with respect to the bottom surface of the fuel tank.
