AUTOMOBILE FUEL-FEED MODULE Russian patent published in 2004 - IPC

FIELD: mechanical engineering; engine.

SUBSTANCE: invention relates to supply systems of internal combustion engines. Proposed fuel-feed module designed for use in supply system of automobile internal combustion engine contains support framework, electric fuel pump, filter, fuel level transmitter with float and intake chamber. Support framework consists of cover with posts press-fitted into cover and getting into channels of bracket flanges. Cover has fuel-feed union, return fuel union and connector socket to supply electric power to fuel pump. Fuel pulsar tube connects fuel-feed union on cover with outlet union of electric fuel pump. Electric fuel pump is secured in bracket by clamp enclosing projecting part of electric fuel pump between electric supply connected socket and output union by means of lips-latches. Post connected with return union plays part of fuel return pipeline. Intake chamber is made in form of bowl whose wall encloses support framework of electric fuel pump, and bottom has at least two cylindrical members used to take in bracket flanges.

EFFECT: simplified design and manufacture of fuel-feed module, improved operation reliability of module.
