US 5,511,957 A · High capacity fuel pump and filter combination

Abstract

In a fuel system for an internal combustion engine powering a motor vehicle, a fuel reservoir canister mounted in a main fuel tank. An annular fuel filter element is enclosed in an axially elongate housing with radially spaced apart inner and outer cylindrical side walls. The housing is received in the canister with its outer side wall bearing on and radially supported by a complementary side wall of the canister. Preferably, a fuel pump and pressure regulator are disposed in the canister preferably so they overlap with and are encircled by the filter housing. The high pressure outlet of the fuel pump is connected to the filter to supply filtered fuel to the engine at a pressure regulated and controlled by the pressure regulator.

A fuel system for furnishing fuel to an engine which comprises:

(a) an electric fuel pump having an inlet and an outlet,
(b) an annular filter element disposed about a central axis,
(c) an annular housing confining said annular filter on the outer and inner peripheries of said filter, said housing providing flow spaces on the inner and outer peripheries of said filter,
(d) means connecting one of the inner and outer flow spaces with the outlet of said fuel pump, and
(e) means connecting the other of the inner and outer flow spaces with a fuel outlet leading to the engine,
whereby pump outlet fuel will flow into one of said inner and outer flow spaces, around said filter, generally radially to the other of said inner and outer flow spaces and to said filter outlet.
