Appl. No.:

12/077400

International Classification:

B05B 1/30
B05B 1/00
F02M 61/10

US Classification:

239575, 239596, 23953311

Abstract:

A lower filter for a fuel injector includes a disk having an annular shape and including a plurality of filter holes. The disk is positioned upstream of a valve guide of an internal valve assembly without contacting the valve guide. The disk prevents internally generated contaminants contained in fuel flowing through the filter holes from reaching a valve guide area and a sealing area of the internal valve assembly. By installing the lower filter upstream of the valve guide and without contact to the valve guide, interference with the guidance and reciprocal movement of the valve is avoided. Application of the lower filter in fuel injectors may reduce the occurrence of injector failures by reducing the number of stuck open conditions in injectors and by reducing the number of hydro lock engine incidents without interference with the valve guide.

International Classification:

B05B 1/30

US Classification:

239575, 239584

Abstract:

A lower fuel injector filter includes a generally planar disk having an annular shape and including a plurality of filter holes. The disk is retained by a valve guide within a valve seat. The disk prevents internally generated contamination particles contained in fuel flowing through the filter holes from reaching a valve and seat interface positioned downstream of the valve guide. The disk may also be retained by a ball valve stop proximate the valve seat.

International Classification:

F02M 61/14

US Classification:

123470

Abstract:

A fuel injector-engine component assembly includes an engine component with a stepped bore defined along an axis and having a stepped bore stop surface facing axially upward. A fuel injector extending along the axis is disposed in the stepped bore and includes a fuel injector stop surface facing axially downward and axially opposing the stepped bore stop surface. An isolation ring is disposed between the engine component and fuel injector stop surfaces for axially isolating the fuel injector from the engine component. The isolation ring includes a rigid support member for limiting the axial motion of the engine component and fuel injector stop surfaces together. The isolation ring also includes a resilient and compliant isolation member located axially between the engine component and fuel injector stop surfaces to provide acoustic and thermal isolation between the fuel injector and the engine component below a predetermined pressure of the fuel injector.

International Classification:

B05B 1/30

US Classification:

239575

Abstract:

An internal lower filter for a fuel injector includes a self-supporting guide guiding a reciprocably activated valve of an internal valve assembly of a fuel injector and a plurality of filter holes formed in said guide filtering fuel flowing through the fuel injector and preventing contaminants contained in the fuel from entering a sealing area of the internal valve assembly. Incorporating the guide filter in accordance with the invention in a fuel injector enables capturing particles or contaminants, generated within the fuel injector during assembly or during operation, before entering the sealing area of an internal valve assembly. Accordingly, failure modes of the injector, such as a stuck open condition that may lead to a hydraulic lock of the engine, can be reduced. By forming the filter holes in a typically used ball guide, no changes are required to the currently used assembly line equipment or the current assembly process.
