    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： An electromagnetically actuatable injection valve, including a nozzle with a shaped end face in combination with a perforated plate through which the fuel flows. The nozzle injection valve has an injection chamber which is defined by a downstream terminal face of the valve closing element and by the perforated plate which is spaced from the nozzle and provided with injection ports. The geometrical embodiment of the injection chamber influences the fuel flow in such a way that a pulse flow vector of the flow penetrates an imaginary jacket face at right angles, so that the injection ports are acted upon substantially by pressure energy. The novel injection valve is especially suitable for fuel injection systems of mixture-compressing internal combustion engines with externally supplied ignition.

    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 the direct injection of fuel into the combustion chamber of an internal combustion engine includes a valve needle situated in a nozzle body, the valve needle being actuable by an actuator and acted upon by a restoring spring in such a manner that a valve-closure member which is in operative connection to the valve needle and faces the combustion chamber is kept in sealing contact with a valve-seat surface in the non-actuated state of the actuator. A first jet-opening angle α1 is assigned to a first lift state of the valve needle and a second jet-opening angle α2 to a second lift state of the valve needle.

    摘要： The injection pump has a pump piston driven with a constant stroke which pumps fuel at injection pressure to an injection nozzle so long as an electrically actuated overflow valve blocks the flow of the fuel overflowing via an overflow conduit to a low-pressure chamber. The overflow valve is a needle valve, the valve needle of which, opening inward toward a pressure chamber that can be placed under injection pressure, by means of a conical closing surface radially defining a needle tip controls a valve seat that widens conically toward the pressure chamber. The cone angle of the closing surface is larger than the cone angle of the associated valve seat and the closing surface forms a sealing edge, the diameter of which is equal to or only slightly smaller than the guide diameter of the guide shank on the valve member. In a preferred embodiment, the needle tip of the valve member has an external contour on its end, adjacent to the closing surface, which directs the fuel flow and reinforces the opening movement. The injection pump is particularly suitable for high-pressure injection in Diesel engines, in order to attain an exact electrical control of the supply onset and supply quantity, if a reservoir chamber defined by a deflecting piston is connected to a high-pressure chamber that includes the pump work chamber.

    摘要： A fuel injector for the injection of fuel into the combustion chamber of an internal combustion engine includes a valve needle guided in a nozzle body, the valve needle being actuable by an actuator and acted upon by a restoring spring in such a manner that a valve-closure member which is in operative connection to the valve needle is retained in sealing contact against a valve-seat surface. Formed at a downstream-side end of the fuel injector is a projection which projects beyond the valve-closure member of the fuel injector.
