    摘要: A fuel injector for directly injecting fuel into the combustion chamber of an internal combustion engine includes a solenoid coil, an armature that can be acted upon by the solenoid coil in a stroke direction in opposition to a first resetting spring, and a valve needle connected to a valve-closure member. The valve needle has a first limit stop for the movable armature, the armature additionally being acted upon by a second resetting spring. A stationary second limit stop is provided for the armature. The second resetting spring acts upon the armature contrary to the stroke direction and, in the resting position, when the solenoid coil is not excited, the second resetting spring holds the armature in position at the second limit stop such that the armature is at a preestablished distance from the first limit stop configured on the valve needle.

    摘要: A method is described for operating a fuel injector for fuel injection systems of internal combustion engines, particularly for the direct injection of fuel into a combustion chamber of an internal combustion engine. The fuel injector has a magnetic coil, an armature acted upon in a closing direction by a resetting spring, and a valve needle, frictionally connected to the armature, for actuating a valve-closure member which, together with a valve-seat surface, forms a sealing seat. The method includes exciting the magnetic coil with a basic current intensity during an opening phase of the fuel injector, shortly before the end of the opening phase, exciting the magnetic coil with a current pulse that is increased compared to the basic current intensity, and, at the end of the opening phase, switching off the current exciting the magnetic coil.

    摘要: An electromagnetically operable valve having an electromagnetic circuit which includes at least one solenoid coil (1), a core used as internal pole, and an armature, as well as a magnet housing (60) at least partially surrounding the solenoid coil (1). The magnet housing (60) is produced from a sheet-metal blank with the aid of rolling or bending. The magnet housing (60) has a middle housing area (630) that is adjoined in the axial direction on both sides by attachment areas (640, 650) which have a smaller outside diameter than the housing area (630). The valve is particularly suitable as a fuel injector for fuel-injection systems of mixture-compressing internal combustion engines with externally supplied ignition.

    摘要: A fuel injector has an actuator for generating a lifting movement and a lift translator filled with a hydraulic medium and deformable in the lifting direction, for transferring the lifting movement of the actuator to a valve needle, provision being made for a compensating chamber for the hydraulic medium, the compensating chamber being connected to an interior space of the lift translator via a throttle opening and enclosed by an elastic casing. Thus, temperature-related quasistatic deformations of actuator, lift translator, and/or valve needle can be compensated for by an exchange of the hydraulic medium between the interior space of the lift translator and the compensating chamber, while the comparatively fast lifting movements of the actuator are transmitted to the valve needle essentially without damping.
