    摘要： A fuel injector, in particular a high-pressure injector for directly injecting fuel into a combustion chamber of a mixture-compression, spark-ignition internal combustion engine, which is characterized in that on a valve seat element a conical section is formed having a valve seat surface, to which an outlet opening is immediately connected on the downstream side. The outlet opening has an intake plane, an outlet plane, and a central axis, the central point of the intake plane being offset with respect to the valve longitudinal axis and the central axis running diagonally with respect to the valve longitudinal axis. Upstream of the valve seat element a disk-shaped swirl element is arranged, which can be used both for generating a right swirl as well as a left swirl.

    摘要： A fuel injector, in particular a high-pressure injector for directly injecting fuel into a combustion chamber of a mixture-compression, spark-ignition internal combustion engine, which is characterized by the fact that at a valve seat element a conical section is formed having a valve seat surface, to which an outlet opening is immediately joined in the downstream direction. The outlet opening has an intake plane, whose central point lies on the valve longitudinal axis, whose central axis, however, runs diagonally with respect to valve longitudinal axis. A disk-shaped swirl element is arranged upstream of the valve seat element. The swirl element has swirl channels, which are distributed over the periphery, the swirl channels having varying geometries or dimensions.

    摘要： A fuel injection valve for fuel injection systems of internal combustion engines includes a core which serves as the internal pole is made of a soft magnetic powder composite material. This powder composite material is an iron powder provided with a polymer additive, where the individual iron particles are coated with an electrically insulating layer. Such a powder composite material ensures a substantial minimization of eddy currents in the magnetic circuit in comparison with materials known previously, such as chromium steel, which are usually used as magnetic materials. The core which is mechanically sensitive and is sensitive to fuel is encapsulated at least with respect to the parts of the injection valve carrying the fuel. A sleeve passes through an internal longitudinal opening in the core which permits fuel flow in its interior and is fixedly attached to a pole part which seals the core toward the bottom. The core and the magnetic coil are thus not exposed to any wetting by fuel. This fuel injection valve is especially suitable for use in fuel injection systems of internal combustion engines with mixture compression and external ignition.

    摘要： A fuel injector, in particular a fuel injector for fuel injection systems of internal combustion engines, has a piezoelectric or magnetostrictive actuator, a valve closing element that can be actuated by the actuator and that works together with a valve seat face to form a seal seat, and a temperature compensation device. The temperature compensation device has a housing that is elastically deformable along a direction of actuation of the actuator, and has at least one throttle that connects an interior space of the housing with a fuel inlet of the fuel injector. The cross-section of this throttle is dimensioned such that an entry and exit of fuel into the housing of the temperature compensation device is enabled when there is a temperature-caused change in length of components of the fuel injector.

    摘要： A fuel injector for fuel injection systems of internal combustion engines, in particular for the direct injection of fuel into a combustion chamber of an internal combustion engine, includes a solenoid coil, an armature that is acted upon in a closing direction by a resetting spring, and a valve needle that is in a form-locking connection with the armature for actuating a valve-closure member, which together with a valve seat surface forms a sealing seat. A cooperates with the resetting spring such that the spring forces of the resetting spring and of the are added together. In this context, the resetting spring is biased over a total lift of the armature and the is biased only over a residual lift of the armature, which is smaller than the total lift.
