    摘要: An engine fuel injector body is assembled using a furnace brazing method to provide structural and hermetic internal joints at interior locations with minimum size and processing. The method of assembling an injector with such an internal hermetic and structural joint may include the steps of providing an annular body member with an annular inner recess having an inner cylindrical surface, forming an annular end recess adjoining the cylindrical surface, fitting a tubular member into the inner recess of the body member with an outer surface of the tubular member engaging the cylindrical surface of the inner recess, placing a brazing ring in the end recess of the body member adjacent the tubular member, and furnace brazing the members together to form the internal hermetic and structural joint. Additional joints may be joined during the same brazing step.

    摘要: An injector valve armature/spacer is formed as an integral tri-function multiple thickness member for an engine fuel injector. The member includes an armature having a center portion with an upper side engagable by a biasing spring and an outer portion with spaced radial openings extending outward from the center portion. An outer rim is connected to the inner portion of the armature by flexible legs extending radially through the radial openings. The rim has a thickness greater than that of the armature by a differential dimension establishing a stroke of the armature. The legs have a thickness less than that of the armature to permit flexing of the legs upon movement of the armature. The integral member is designed for manufacture in multiple layers using electroforming, optionally combined with metal etching.

    摘要: An electromagnetic fuel injector comprises a body having a fuel inlet and a fuel outlet and a base comprising a valve seat sealably connected to the body. A disk-shaped armature disposed at the fuel outlet for controlling the flow of fuel has an upper surface and a lower surface that comprises a sealing interface with the valve seat. A ring-shaped flexural element comprising a plurality of spaced flexural legs is in contact with the injector body and the upper surface of the armature and provides a spring bias between the body and armature upper surface. When the injector is closed, spring bias between the body and armature upper surface maintains the armature in a sealing position with the valve seat, and when the injector is open, increased spring bias between the body and armature upper surface impels the armature to return to a sealing position with the valve seat.
