摘要： An electromagnetically operable valve having an electromagnetic circuit which includes at least one solenoid coil, a core used as internal pole, and an armature, as well as a magnet housing at least partially surrounding the solenoid coil. The magnet housing is produced from a sheet-metal blank with the aid of rolling or bending. The magnet housing has a middle housing area that is adjoined in the axial direction on both sides by attachment areas which have a smaller outside diameter than the housing area. 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 for fuel-injection systems of internal combustion engines includes two preassembled, independent assemblies. A functional part includes an electromagnetic circuit and a sealing valve, while a connection part is formed mainly by a hydraulic connection and an electrical connection. In the ready-mounted injector, electrical connecting elements and hydraulic connecting elements of both assemblies cooperate, thus ensuring a reliable electrical and hydraulic connection An extrusion coat in the interconnection region provides mechanical joining of both assemblies, great stability of the valve and sufficient imperviousness.

摘要： A fuel injector has a piezoelectric or magnetostrictive actuator, which actuates a valve-closure member cooperating with a valve-seat surface a sealing seat. An hydraulic coupler includes a master piston, a slave piston, and a coupler volume formed in-between, the coupler volume being connected to a compensating chamber via a throttle. An elastic flexible section delimits the compensating chamber at least partially, and the coupler volume, the throttle, and the compensating chamber are filled with an hydraulic medium. The flexible section exerts a pressure on the hydraulic medium due to prestressing, and the force of a compression spring, which is braced either directly and/or via fixed components on the slave piston and the master piston, is directed with an initial stress in such a way that the force enlarges the coupler volume.

摘要： A fuel injector, in particular for the direct injection of fuel into a combustion chamber of an internal combustion engine, includes a valve needle that has at its injector end a valve-closure member that works together with a valve-seat surface formed on a valve-seat member, to form a sealing seat. The fuel injector also includes at least one swirl duct; a swirl chamber formed on the valve-seat member, and a plurality of injection openings that open out from the swirl chamber, through which the fuel, provided with a swirl, is simultaneously injected. The at least one swirl duct is formed in the valve-seat member or in a swirl disk adjacent to the valve-seat member.

摘要： A fuel injector for fuel-injection systems of internal combustion engines in which a guide disk is provided upstream of a valve seat, the guide disk fulfilling several functions. In addition to guiding an axially movable valve needle, the guide disk takes on a flow-through function for the fuel. To this end, a passage hole having alternating guide regions and flow regions over its outer circumference is provided in the guide disk, the opening width of the passage hole defined by the guide regions being smaller than the opening width defined by the flow regions. The fuel injector is particularly suitable for use in fuel-injection systems of mixture-compressing internal combustion engines with externally supplied ignition.
