| description | A fluid injector (10) for delivery of fluid to an internal combustion engine has an injector body (12) defining a central axis (20), a fluid discharge opening (50) coaxial with the central axis having a valve seat (52) extending thereabout, and a valve element (60) normally seated on the valve seat to close the fluid discharge opening. The valve element is operable to move off of the valve seat to open the fluid discharge opening allowing fluid to pass through. A filter-valve guide (64) is coaxially positioned upstream of the valve seat and includes an annular closed bottom (66), an outer wall (68) extending coaxially upwardly from the annular closed bottom to define an outer diameter, and an inner wall (70) extending coaxially upwardly from the annular closed bottom to define a central opening (72). The valve element passes through the central opening and the guide inner wall guides the valve element as it moves relative to the valve seat. The annular closed bottom includes filtration openings (74) to filter particulates from fluid passing therethrough, such that particulates are prevented from flowing to the valve seat. |
