Abstract
A fuel supply system is installed inside a fuel tank as part of a cover closing an opening of the fuel tank. The fuel filter is integrally fixed to the cover and a fuel pump is mounted via the fuel filter. The fuel filter is in the shape of a partial annulus disposed in a certain angular range. Such system parts as a pressure regulator, an electric connector, a fuel level gauge and a fuel pipe are contained in the remaining angular range of the fuel pump periphery where the fuel filter is not disposed.
Claims24
A fuel supply system for supplying fuel to a fuel consumption unit, comprising:
- a fuel pump having a cylindrical appearance;
- a fuel filter for filtering the fuel to be delivered to said fuel consumption unit and having a shape corresponding to an outer periphery of said fuel pump;
- other parts forming a part of said fuel supply system, said other parts being separate from said fuel pump and said fuel filter;
- a holding member holding a plurality of parts for said fuel supply system, said holding member holding said fuel pump, holding said fuel filter around the outer periphery of said fuel pump windingly and holding said other parts around the outer periphery of said fuel pump at a position overlapping in the peripheral direction of said fuel pump with respect to said fuel filter.
A holding unit of a fuel supply system for holding a plurality of parts of said fuel supply system including a fuel pump and a fuel filter, said holding unit comprising:
- a cylindrical fuel pump holding portion holding said fuel pump;
- and
- a parts-holding portion around an outer circumference of said fuel pump, wherein
- said parts-holding portion is divided into a first partial annular holding region for holding said fuel filter and a second partial annular holding region adjacent to said first holding region in the circumferential direction for holding other parts, said first and second holding regions being displaced with respect to one another about the outer periphery of said fuel pump.
A holding unit of a fuel supply system for holding a plurality of parts of said fuel supply system including a fuel pump and a fuel filter, said holding unit comprising:
- a cylindrical fuel pump holding portion holding said fuel pump;
- and
- a parts-holding portion disposed on an outer circumference of said fuel pump,
- wherein said parts-holding portion is divided into:
- (a) a first holding region disposed in an outer circumferential direction of said fuel pump for holding said fuel filter, and (b) a second holding region also disposed in said outer circumferential direction and overlapping the first holding region, for holding other parts.
A holding unit of a fuel supply system for holding a plurality of parts of said fuel supply system including a fuel pump and a fuel filter, said holding unit comprising:
- a cylindrical fuel pump holding portion holding said fuel pump;
- and
- a parts-holding portion disposed at an outer periphery of said fuel pump;
- the parts-holding portion having an annular ring shape divided into a first holding region having a C-shaped cross section and a second holding region having a cross-sectional shape spanning a gap left between ends of said C-shaped cross section.
A holding unit of a fuel supply system for holding a plurality of parts of said fuel supply system including a fuel pump and a fuel filter, said holding unit comprising:
- a cylindrical fuel pump holding portion holding said fuel pump;
- and
- a parts-holding portion disposed at an outer periphery of said fuel pump;
- said parts-holding portion being divided into a first holding region disposed in a peripheral circumferential direction for holding said fuel filter and a second holding region disposed adjacent to said first holding region in the peripheral circumferential direction for holding other parts;
- and
- each of said first and second holding regions having surfaces respectively defined by said pump holding portion and said parts-holding portion.
