摘要： A fuel injector, in particular a fuel injector for fuel-injection systems of internal combustion engines, includes a first magnetic coil cooperating with a first armature, a second magnetic coil cooperating with a second armature, and a valve needle which is in force-locking connection with the first armature via a first flange and to the second armature via a second flange, to actuate a valve-closure member. A restoring spring acts upon the valve needle in a closing direction of the fuel injector. A first positioning spring, situated between the first flange and the first armature, acts upon the first armature in the closing direction of the fuel injector, while a second positioning spring, situated between the second flange and the second armature, acts upon the second armature in an opening direction of the fuel injector.

摘要： A fuel injection valve for a fuel injection system of an internal combustion engine, in particular for injecting fuel directly into the combustion chamber of the internal combustion engine. The fuel injection valve has a magnet coil, an armature that can be pulled by the magnet coil in a direction of lift against a first return spring, and a valve needle. The valve needle has a first stop surface for the armature, which can be moved relative to the valve needle. The armature is acted upon by a second return spring. In addition, a stationary second stop surface for the armature is provided. The second return spring acts upon the armature in a direction opposite to the lift and in an inoperative position, when the magnet coil is not energized, and holds the armature in contact with the second stop surface so that a distance between the armature and the first stop surface provided on the valve needle is predefined.

摘要： A fuel injection valve, in particular a high-pressure injection valve for the direct injection of fuel into the combustion chamber of a compressed mixture, externally ignited internal combustion engine, has in a guide and seat area provided at the downstream end of the valve which area is formed by three disk-shaped elements. A swirl element is nested between a guide element and a valve seat element. The guide element, which can move radially in the assembled valve and which has an inner guide opening, serves to guide an axially movable valve needle which extends through it, while a valve closing section of the valve needle acts in concert with a valve seat surface of the valve seat element. The guide element is spring-loaded through a compression spring which acts upon it.

摘要： An electromagnetically actuable valve, in particular an injection valve for fuel injection systems of internal combustion engines is provided. The actuable valve has a throttling point that joins a core and a connector part to one another. An annular insert that supports the throttling point in a radial direction is provided. The use of the annular insert makes it possible to utilize the advantages of the design of a valve tube with the throttling point, and at the same time creates the stability necessary for high-pressure valves. The annular insert is made from electrically nonconductive material or configured with an interruption at at least one point and mounted in an electrically insulated fashion. This prevents eddy currents, which have a negative effect on switching times, in the annular insert. The annular insert is located at least partially within an influence region of a magnetic field of a magnet coil, in the presence of a changing magnetic field.

摘要： A fuel injection valve, in particular, a high-pressure injection valve, for injecting fuel directly into a combustion chamber of a compressed-mixture internal combustion engine with externally supplied ignition. The fuel injection valve includes a guide and seating area formed by three disc-shaped elements provided at the downstream end of the valve. A swirl element is embedded between a guide element and a valve seat element. The guide element is used to guide a valve needle which passes through it and can move in the axial direction, while a valve closing segment of the valve needle interacts with a valve seat surface of the valve seat element. The swirl element has an inner opening area with multiple swirl channels which are not joined to the outer circumference of the swirl element. The entire opening area extends completely across the axial thickness of the swirl element.

摘要： A method and device for triggering a solenoid valve for injecting fuel into an internal combustion engine is described. The triggering phase of the solenoid valve is subdivided into a pull-up phase and a holding phase. During the pull-up phase, a valve needle of the solenoid valve is caused to open by a first current intensity flowing through a magnetic coil of the solenoid valve. During the holding phase, the valve needle is held in the open state by a second, lower current intensity flowing through the magnetic coil. At least once at the beginning of the pull-up phase, a booster phase is activated during which a pulse-shaped booster current from a booster capacitor charged to a high voltage flows through the magnetic coil. During the triggering phase of the solenoid valve, a plurality of booster pulses are activated in succession, whose time position within the triggering phase is freely selectable.

摘要： An internal combustion engine for motor vehicles, with an intake tube for aspirating combustion air, in which the tube leads to at least one combustion cylinder, and in which tube a throttle valve is disposed. The intake tube effects a mixing of combustion air and fuel vapor downstream of the throttle valve. For the sake of intensive mixing of fuel vapor and combustion air into a largely homogeneous mixture, the fuel vapor generated in a fuel evaporator outside the intake tube is introduced via a delivery device into air turbulence paths that unavoidably develop downstream of the throttle valve in the intake tube as a consequence of the geometry of the intake tube and/or throttle valve.

摘要： An electromagnetically operated valve, in particular a fuel injection valve for fuel injection systems, has a core surrounded by a magnet coil and an armature adjacent to the core for operating a valve closing body that interacts with a valve seat body. A reflux body surrounding the armature is magnetically isolated from the core by an isolation point. The core and/or the reflux body is made of a ferritic or ferromagnetic material whose permeability depends on the mechanical stress in the material. The core and/or the reflux body is mechanically deformed in a boundary area between the core and the reflux body to form the magnetic isolation point.
