    摘要： A fuel injector, in particular for the direct injection of fuel into a combustion chamber of an internal combustion engine, having a valve-closure member which cooperates with a valve-seat surface formed on a valve-seat body, to form a sealing seat, includes at least one spray-discharge orifice provided downstream from the sealing seat. The spray-discharge orifice has a guide region and an exit region arranged at its discharge-side end. The exit region widens in a stepped manner by at least one first step and/or at least in part continuously beginning with a transition from the guide region into the exit region. A fuel jet which emerges from the guide region at the transition and widens essentially uniformly at a jet angle, passes a discharge-side end of the exit region with a gap dimension of a gap after a distance s, the gap dimension being greater than zero and a first volume remaining in the exit region between the fuel jet and the inner walls of the exit region.

    摘要： A fuel injector for fuel-injection systems of internal combustion engines includes a solenoid coil, a valve needle that is in operative connection with the solenoid coil and acted upon by a restoring spring in a closing direction in order to actuate a valve-closure member which forms a sealing seat together with a valve-seat surface formed at a valve-seat member, and at least two spray-discharge orifices, which are formed in the valve-seat member. In a discharge region, the spray-discharge orifices are in connection with capillaries formed in the end face of the valve-seat member.

    摘要： The fuel injection valve according to the invention enables an improvement in the fuel preparation and hence a more uniform fuel-air mixture while simultaneously supplying different inlet valves of an engine from one fuel injection valve. Downstream of the valve seat face of the fuel injection valve, the fuel enters a central opening from which tangential conduits lead to at least two swirl chambers disposedly spaced apart from one another and which discharge into these chambers at a tangent. From the center of each swirl chamber, which may be embodied in an attachment, a respective metering opening leads to the outside, by way of which fuel can be injected, well prepared, in the form of cone-shaped fuel streams. The fuel injection valve is suitable either for supplying individual inlet valves with a plurality of fuel streams, or for supplying different inlet valves of the engine with fuel at the same time.
