摘要： An electromagnet which serves particularly to control a fuel injection valve for fuel injection systems in internal combustion engines. The electromagnet includes an inner core of soft-magnetic material, which is surrounded by a magnetic coil. An outer core at least partly surrounds the magnetic coil and has an outer pole located in the same plane as an inner pole of the inner core. On one side of the magnetic coil, between the inner core and the outer core, there is a first annularly embodied and radially magnetized permanent magnet, and on the other side of the magnetic coil there is a second annularly embodied and radially magnetized permanent magnet. Facing the poles, there is an armature, which at one end is joined to a valve needle that has a valve body cooperating with a valve seat, and on its other end forms a first working air gap with the outer pole and a second working air gap with the inner pole. The permanent magnets are poled such that their magnetic fields at the working air gaps extend counter to the electromagnetic field induced by the magnetic coil.

摘要： An injector for the metered ejection of a fluid, in particular fuel, has a housing and a plastic extrusion coating, which encloses the housing, and from which the housing protrudes at an upper housing end on the fluid inlet side and at a lower housing end on the fluid ejection side. To achieve a so-called “fording capability” of the injector, the peripheral separation point of the housing and the plastic extrusion coating, at the lower end of the plastic extrusion coating, is sealed, preferably with the aid of a sealing collar.

摘要： An electromagnetically operatable valve, in particular a fuel injector for fuel injection systems of internal combustion engines, includes a magnetic circuit having a core, a solenoid, an armature, which operates a valve closing body cooperating with a fixed valve seat and is drawn against the core when the solenoid is excited, and is held on the valve closing body by a closing body carrier representing a part of a valve needle. The spherical valve closing body is secured on the closing body carrier in a non-positive manner due to the shape of the corresponding connecting surfaces. The valve is suitable in particular for use in fuel injection systems of mixture-compressing, externally ignited internal combustion engines.

摘要： The present invention relates to a method for adjusting the valve lift of an injector, especially a fuel injector for mixture-compressing externally ignited internal combustion engines. The valve has a fuel intake, an energizable actuation device, which moves a valve needle having a valve closing component, a fixed valve seat formed on a valve seat element, with which the valve closing component interacts for opening and closing the valve, and a fuel outlet. Furthermore, the valve has a valve seat support provided with an internal longitudinal opening for accepting the valve needle. The valve needle executes a lift between a valve closing position and a valve opening position. The valve seat support is preformed having at least one radially-outward-protruding raised section. In order to change the lift of the valve needle, the raised section is plastically deformed in radial direction toward the longitudinal opening.

摘要： A fuel injector, in particular for direct injection of fuel into the combustion chamber of a mixture-compressing, spark-ignited internal combustion engine, comprises an armature that coacts with a magnet coil, and comprises a valve needle, joined to the armature, on which is provided a valve-closure member that, together with a valve seat surface, forms a sealing seat. The valve needle has, downstream from the armature, a clamping sleeve whose axial position on the valve needle determines the height of a pre-stroke gap configured between the armature and an engaging flange that is joined nonpositively to the valve needle, the clamping sleeve being of tubular configuration and having a slit extending in the axial direction.
