Abstract
A fuel supply apparatus includes a suction filter; a fuel pump which is connected to the suction filter by a connecting pipe through which fuel that has passed through the suction filter is discharged; a fuel passage which protrudes from an upper portion of the fuel pump; and a one-way valve which is provided at an inlet portion of the fuel passage. In the fuel supply apparatus, a high-pressure filter is provided in a fuel passage on a downstream side of the one-way valve, and the suction filter and the high-pressure filter in the fuel passage remove dust in the fuel.
Claims26
A fuel supply apparatus comprising:
- a fuel pump which discharges fuel,
- a cover portion which is formed above the fuel pump,
- a fuel passage which is provided in the cover portion;
- and
- a high-pressure filter provided in at least one of the fuel pump and the fuel passage, and which removes dust in the fuel discharged from the fuel pump.
A fuel supply apparatus comprising:
- a suction filter which removes dust in fuel;
- a fuel pump which is connected to the suction filter by a connecting pipe through which the fuel that has passed through the suction filter is discharged;
- a fuel passage which protrudes from an upper portion of the fuel pump;
- and
- a high-pressure filter which is provided in the fuel passage so as to remove dust in the fuel.
