A fuel injector assembly includes a valve housing, a valve stem that is disposed in the valve housing, a magnetic coil that surrounds the valve housing and is used to displace the valve stern within the valve housing, and a terminal blade. The terminal blade includes a bus bar that provides an electrical connection between the magnetic coil and an external connector. In addition, the terminal blade includes a clip that is connected to the bus bar at a clip first end and to the valve housing at a clip second end. The clip includes a sacrificial portion that is configured to part, for example by dissolving, when the terminal blade undergoes an overmolding process. As a result of the overmolding process, the clip is separated into multiple, spaced portions.

A method of making a fluid injector for a gas turbine engine includes depositing material onto a piece of tube stock. The method includes machining the deposited material into a fluid injector component. Depositing can include laser cladding the material onto the piece of tube stock. The method can include placing or flowing braze into a braze joint location between the deposited material and another fluid injector component and forming the braze into a braze joint in the braze joint location.

A control valve assembly of a fuel injector includes a first valve arrangement wherein a first valve spool is guided in a first hydraulic bore provided in a body of the assembly. The control assembly further includes a first tubular sleeve having a seating portion which end face defines the first seating face, the first sleeve being fixed in the first hydraulic bore and the first spool extending through the sleeve.

A component for an injection system for mixture-compressing, spark-ignition internal combustion engines, which is used to apportion a fluid under high pressure, in particular a highpressure line or fluid manifold. The component includes a main body on which at least one hydraulic connection is provided, at least the main body having the connection being formed by single stage or multistage forging, an interior being formed on the main body by chip-removing machining after forging and a connection channel, which intersects with the interior in an intersection region, being formed at the connection by chip-removing machining after forging. The intersection region is deburred by mechanical deburring. An injection system and a method for producing such a component are also described.

A boring device includes: a rotatable body, which has a workpiece holder, a valve seat receiver and a debris passage portion; a laser emitter; a pump and a control unit. The workpiece holder can hold a nozzle body. The valve seat receiver contacts a valve seat of the nozzle body that is held by the workpiece holder. The laser emitter emits a laser beam to an outer wall of the nozzle body to bore injection holes at the nozzle body. The debris passage portion includes a debris passage that is placed on a radially inner side of the valve seat receiver and guides debris formed at the time of boring the injection holes with the laser beam. The pump vacuums the debris through the debris passage. The control unit controls a laser output power of the laser emitter and a suction force of the pump.

A fuel distributor rail for a fuel injection system for an internal combustion engine in motor vehicles, in particular for gasoline engines. The fuel distributor rail comprises a main tube, wherein the main tube has a fuel channel extending in the longitudinal direction of the main tube. The main tube comprises at least two outlet openings, wherein the outlet openings branch off the fuel channel. A connecting element is arranged on the main tube, wherein the connecting element has an attachment wall that rests against the main tube. The connecting element is connected to the main tube in a material bonded manner and comprises at least two connecting pieces. The connecting pieces have a connecting channel each for the fluidic connection of an outlet opening to each injection nozzle.

A high-pressure fuel pump includes a piston and a sealing device. The piston includes an end portion. The sealing device is disposed on the end portion, faces a drive of the fuel pump, and is configured to radially surround the piston. The piston is displaceable along a longitudinal axis relative to the sealing device. The sealing device includes a first and a second sealing portion which extend round in a radially internal manner. The first and the second sealing portions are each located at mutually spaced-apart axial end regions of the sealing device. The first and the second sealing portions are present on an injection-molded component which is subsequently processed in a cutting manner.

Disclosed is a device for protecting the back wall of a fuel injector nozzle during drilling of nozzle holes.
