ABSTRACT:
A valve assembly includes a first body with a first conical valve seat and a locating bore centered about a first axis. A second body is press fit attached to the first body and has a second conical valve seat with a second axis positioned in opposition to the first conical valve seat. An elongated valve member with a centerline has an upper conical valve surface and a lower conical valve surface trapped between the first conical valve seat and the second conical valve seat. A guide portion of the elongated valve member moves in a guide bore defined by one of the first body and the second body. The first axis, the second axis and the centerline are concentrically linked via the press fit attachment of the second body in the locating bore of the first body. The valve assembly is preferably utilized as a needle control valve assembly in a fuel injector.
