Abstract:
A fuel injector for delivery of fuel to an internal combustion engine comprising an injector body defining a central axis, a fuel discharge opening coaxial with said central axis having a valve seat extending thereabout, a valve element normally seated on said valve seat to close said fuel discharge opening and operable to move off of said valve seat to open said fuel discharge opening allowing fuel to pass therethrough, a filter-valve guide positioned coaxially with said central axis, upstream of said valve seat, comprising an annular closed bottom, an outer wall extending coaxially upwardly from said annular closed bottom, and an inner wall extending coaxially upwardly from said annular closed bottom defining a central opening for passage of said valve element wherein said inner wall guides said valve element as said valve element moves relative to said valve seat, and said annular closed bottom comprising filtration openings to filter particulates from fuel passing therethrough, wherein particulates are prevented from flowing to said valve seat.
