초록 ▼

The module contains a tubular filter cartridge within an enclosure and a fuel pressure regulator mounted on an end wall of the enclosure. The fuel pressure regulator is entirely self-contained allowing it to be a mass-produced part that can be used in various module configurations having differently shaped enclosures and differently shaped filter cartridges. In the illustrated embodiment, the pressure regulator separably mounts on the exterior of the end wall of the enclosure. A retention ring that has certain features is used to mount the pressure regulator with a tight fit on the enclosure end wall. The enclosure also has features for a tight fit in the socket of a fuel pump module into which the pressure regulator/filter module is inserted when used.

대표청구항 ▼

A fuel pressure regulator/fuel filter module for use in filtering and pressure-regulating fuel that is pumped from a fuel tank to an automotive engine, the module comprising: an enclosure comprising a side wall and at least two end walls bounding an interior, a first fuel port in one of said end walls via which fuel from the tank is pumped into the module, a second fuel port in said one end wall via which excess fuel is returned to the tank, a third fuel port in the other of said end walls via which filtered, pressure-regulated fuel is delivered to the engine, a tubular fuel filter cartridge that is disposed within said enclosure and comprises filter media having an I.D. surface bounding a central passage and an O.D. surface spaced radially outwardly of said I.D. surface, means fitting an axial end of said cartridge to the other of said end walls of said enclosure to place said central passage in fluid communication with said third fuel port, means for preventing fuel that has entered said enclosure via said first fuel port from passing to said central passageway of said cartridge other than through said filter media, and a self-contained fuel pressure regulator comprising: a housing that is disposed on said one end wall of said enclosure and having a pressure-regulating port and an excess fuel return port, and a pressure regulating mechanism within said housing that is operable to cause excess fuel to be conveyed along an excess fuel return path extending through said housing from said pressure-regulating port to said excess fuel return port when fuel pressure at said pressure-regulating port exceeds a regulation pressure, and means placing said excess fuel return path through said housing in series flow relationship with said second fuel port of said enclosure.
