摘要： There is provided a coupling process whereby two components can be coupled together at high positional precision regardless of precision of a single component. A softer component 17 of two components 15, 17 to be coupled together is subjected to shearing by a corner 15c of a harder component 15 while respective parts of the two components 15, 17, positioning of the respective parts being required, are kept as-positioned state with the use of a mandrel 31, and a side face of the corner 15c is fitted to a sheared surface 17c of the softer component 17 during shearing in progress, subsequently coupling the two components 15, 17 together at a fitting surface by plastic coupling, press-fitting, or welding.

摘要： A fuel injector for fuel ignition systems of internal combustion engines includes a magnetic circuit having a core, a magnetic coil and an armature, and a movable valve needle, which has a valve-closure member that cooperates with a fixed valve seat, the valve seat being shaped on a valve-seat member and being provided with a valve-seat support in which the valve-seat member is inserted. At least one metallic component of the fuel injector, in this context, has a serrated structure on its outer circumference for producing a solid connection to a corresponding component made of plastic. The plastic components may be the connection piece, the valve-seat support, the coil shell and the connecting pipe of the valve needle. The fuel injector is particularly suitable for use in fuel-injection systems of mixture-compressing internal combustion engines having externally supplied ignition.

The fuel injector includes an electromagnetic actuating element having a magnetic coil, a core and a valve jacket as the outer magnetic circuit component and a movable valve-closure member which interacts with a valve-seat surface assigned to a valve-seat member. The core and a connecting tube in an inner opening of a thin-walled valve sleeve and the valve jacket on the outer circumference of the valve sleeve are firmly connected to the valve sleeve by pressing them therein/thereon. The fixed press connection between two of these metallic components of the fuel injector is characterized in that at least one of the component partners has a structure including grooves in its press area and/or the particular press area has an inlet rounding in at least one transition to an adjacent component section.

摘要： A fuel injector for fuel-injection systems of internal combustion engines. The fuel injector includes an electromagnetic actuating element having a solenoid coil, a core and a valve cover as external solenoid circuit component, and a movable valve-closure element, which cooperates with a valve-seat surface assigned to a valve-seat body. The core and a connection pipe are fixedly connected in an inner opening of a thin-walled valve sleeve by being pressed into place, and the valve cover at the outer circumference of the valve sleeve is firmly connected to the valve sleeve by being pressed onto it. The firm press-fitted connection of in each case two of these metallic components of the fuel injector is characterized by the fact that at least one of the partner components has in its press-fitting region a structure with score marks, and/or the particular press-fitting region has an intake rounding in at least one transition to an adjoining component section. To safely contain abrasion particles produced in the press-fitting action, starting from the press-fitting region of a partner component, first a recessed region adjoins, which is followed by a press lip, which radially projects further to the outside on the outer contour of this one component partner.

摘要： A process for producing an electromagnetic fuel injection valve is provided, the electromagnetic fuel injection valve having a structure in which a valve assembly formed by coaxially joining a movable core and a valve body is spring-biased toward the side on which the valve assembly is seated on a valve seat while restricting an end thereof that is in proximity to a fixed core, and in the process a first distance (L1) between the front end of the fixed core (22) and the front end of a cylindrical magnetic body (9) is measured, a stopper (28) and the movable core (18) are formed so that a second distance (L2) between an annular shoulder portion (10c) of a valve seat member (10) and the rear end of the stopper (28) projecting by a predetermined amount from the rear end of the movable core (18) in a state in which the valve seat member (10) and the valve assembly (17) are held coaxially is smaller than the first distance (L1) by a desired value, and the cylindrical magnetic body (9) and the valve seat member (10) are butt-welded in a state in which a tubular press-fit portion (10a) is press-fitted into a front portion of the cylindrical magnetic body (9) until the annular shoulder portion (10c) abuts against the front end of the cylindrical magnetic body (9). This enables the stroke of the valve body to be adjusted easily while reducing the cost, and the valve seat member and the cylindrical magnetic body to be joined while enhancing the coaxial precision.

摘要： Methods of forming a hermetic seal between fuel system components are provided. One of the methods can be achieved by passing a light beam through a wall of a polymeric member to an inner surface of the wall that surrounds an outer surface of a polymeric body and defines an internal passage for a flow of fuel; and welding the inner surface of the polymeric member to the outer surface of the polymeric body to provide a hermetic seal at the respective inner and outer surfaces against the flow of fuel. Another method can be achieved by disposing an adhesive on an inner surface of polymeric member that surrounds an outer surface of a polymeric body and defines an internal passage for a flow of fuel; and activating the adhesive to bond the polymeric member to the polymeric body.
