The present invention relates to an injector for injecting fuel, comprising an injector housing for receiving at least one injector component, and an electromagnet for activating a valve for opening and closing the injector, wherein the electromagnet comprises a coil winding and a magnetic body, wherein the injector housing is formed in one piece with the magnetic body.

An injector includes a nozzle portion to inject fluid, a coil to generate a driving force to open and close the nozzle portion, and a molded resin that seals the coil. A cooling jacket has a flow path to cause cooling fluid to flow therethrough. The cooling jacket houses the injector and has an opening in an end opposite to the nozzle portion. A sealing material is filled in a space between the cooling jacket and the molded resin.

Various embodiments include an adjusting filter for a fluid injector valve comprising: an elongate filter sleeve having an inlet and an outlet; and a filter insert. The filter sleeve includes a filter accepting section at the inlet, a press-fit section, a centring section at the outlet, and a spring engaging surface surrounding the outlet. The press-fit section is arranged between the filter accepting section and the centring section. The filter insert is arranged in the filter accepting section. The filter accepting section has an outer diameter smaller than an outer diameter of the press-fit section. The centring section has an outer diameter smaller than the outer diameter of the press-fit section.

A valve system of a vehicle includes: a housing that is electrically conductive and made of a metal and that includes: an inlet configured to receive a fluid; an outlet configured to output the fluid; and a fluid channel fluidly connecting the inlet and the outlet; a pintle disposed within the housing and that is electrically conductive and made of a metal; a ball that is mechanically fastened to the pintle, that is configured to close the outlet, and that is electrically conductive and made of a metal; an armature that is mechanically fastened to the pintle, that is disposed within the housing, and that is electrically conductive and made of a metal; a solenoid coil that is disposed within the housing and that surrounds the pintle; and an electrically insulative material configured to insulate the pintle from the housing.

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 high-pressure 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 high pressure filter including first and second housings having complimentary tapered surfaces, a gasket located between the tapered surfaces, a filter element centrally disposed within the housings, and a compression collar fitted over the second housing and threaded onto the first housing is provided. Methods of making and using high pressure filters are also provided.

To obtain, at low cost, a fuel rail that maintains low hardness and good formability before being formed into a tube stock, can be made to form a welded pipe, and has high-strength properties with which the fuel rail can withstand a high fuel pressure even when formed so as to be relatively thin. A fuel rail for gasoline direct injection that is used at a fuel pressure of at least 30 MPa and is formed from an iron-alloy welded pipe. The fuel rail comprises an iron alloy that contains chemical components of C, Si, Mn, P, S, Nb, and Mo. The plate thickness t and the outer diameter D of the fuel rail have a ratio t/D of 0.2 or less. A bainitic structure can be precipitated by brazing the fuel rail in a furnace during manufacturing.

Provided is a fuel distribution pipe connected to a fuel pipe and distributes and supplies fuel to a plurality of fuel injection devices, comprising: a tubular base material forming a body of the fuel distribution pipe; and a plating layer formed on a surface of the base material, wherein the base material includes a sealing surface formed on an inner peripheral surface thereof and comes into press-contact with the fuel pipe, and wherein a thickness of the plating layer on the sealing surface is thinner than that of the plating layer on an outer peripheral surface of the fuel distribution pipe.

A martensitic stainless steel contains 0.20 mass %C0.60 mass %, 0.10 mass %N0.50 mass %, 14.00 mass %Cr17.00 mass %, 1.00 mass %Mo3.00 mass %, 0.20 mass %V0.40 mass %, Si0.30 mass %, Mn0.80 mass %, P0.040 mass %, S0.040 mass %, Cu0.25 mass %, Ni0.20 mass %, and the balance Fe with inevitable impurities.

A fuel delivery rail includes a rail body having an outer diameter and an inner diameter. The inner diameter defines an interior channel. The fuel delivery rail includes an input port providing access to the interior channel for fuel to enter the interior channel. A plurality of output ports allow the fuel to exit the interior channel, wherein the fuel deliver rail is fabricated from a microalloy steel comprising the following composition by weight: 0.28%<carbon<0.31%; 0.65%<silicon<0.80%; 1.40%<manganese<1.50%; 0.0%<phosphorus<0.015%; 0.012%<sulfur<0.025%; 0.15%<chromium<0.25%; 0.12%<vanadium<0.15%; 0.0%<molybdenum<0.05%; 0.0%<nickel<0.10%; 0.008%<titanium<0.015%; 0.015%<nitrogen<0.020%; 0.0%<aluminum<0.01%; 0.0%<copper<0.25%, the remainder being iron and impurities inherent in processing.
