摘要： A fuel injection nozzle has a valve seat assembly with an upstream and a downstream seat interconnected by a longitudinally extending passage and by a bypass extending from a location upstream of the first seat to a chamber located intermediate of the two seats. A popper valve assembly has upstream and downstream valve members interconnected by a spacer member disposed within the chamber and operable relative to respective valve seats to regulate flow through the nozzle. A biasing member urges the valve member into a normally closed position in which the upstream valve member is unseated and the downstream member is seated to interrupt flow therethrough and out of the nozzle. Introduction of a fuel pulse into the nozzle moves the upstream valve member into engagement with its valve seat to thereby unseat the downstream valve member from its valve seat to allow fuel flow through the bypass around the upstream valve/seat wherein the fuel is discharged into the chamber intermediate of the two valve members. The fuel undergoes a pressure drop upon its exit from the bypass and is subject to movement about the chamber and the spacer member to optimize the atomization of the fuel as it exits the nozzle through the open, downstream valve/seat.

摘要： Each swirl passages of the needle guide and fuel swirl member of a fuel injector has a longer and wider entrance portion and a shorter and narrower exit portion to allow only the latter portion, not the former portion, to perform a metering function. Production of swirl passages is facilitated and more consistent metering results.

摘要： An improved fuel injector for an internal combustion engine which produces highly accurate fuel delivery control by providing a precise closing of the valve without secondary openings caused by rebound or bouncing of the valve from its seat surface after initial closing. Valve rebound is eliminated by a hydraulic cushion formed between parallel surfaces of the movable valve and its stationary guide whereby a thin boundary layer of liquid fuel caught between closely spaced surfaces is compressed just prior to engagement of the valve with its valve seat. This generates an opposing force to the force tending to close the valve.

摘要： In a fuel injector, a swirl generator operates to impart a tangential or swirl component to the fuel as it is expelled from the injector. The mass of the swirl generator is minimized so as to maximize the actuating speed of the injector. The swirl generator develops a pressure drop across the generator during the time the fuel is expelled which pressure drop aids in enhancing the closure time of the injector. The swirl generator provides damping to the needle valve upon both opening and closing. The swirl generator minimizes the volume of residual fuel remaining in the injector.

摘要： The fuel injector has several swirl passages in a fuel swirl and needle guide member that direct swirl fuel onto the frusto-conical surface of a valve seat member that is disposed at the injector's nozzle end. The needle lift is such that with the needle unseated to open the injector to flow, the swirl fuel is throttled as it passes between the rounded tip end of the open needle and the frusto-conical surface of the seat member. The throttling tends to spread the swirl flow so that it is more uniform in the circumferential sense. If the injector is closed before equilibrium flow occurs, a toroidal shaped fuel cloud is created; if the injector is closed after equilibrium flow occurs, an ellipsoidal shaped fuel cloud is created.

摘要： An injection valve for fuel injection systems in internal combustion engines which comprises a movable valve element cooperating with a valve seat disposed in a nozzle body, with a guide bore provided downstream of the valve seat. A swirl insert is partially compressed in the guide bore and disposes open swirl channels in the direction of its circumference. The swirl channels extend in an axial direction from one end of the swirl insert to the other, are slanted toward the longitudinal shaft of the injection valve and discharge in a tangential direction into a preparation bore. The swirl channels serve simultaneously as metering channels whose throttling length is adjustable by displacing the swirl insert inside the guide bore.

摘要： In an electromagnetically actuatable fuel-injection valve for injection systems for internal-combustion engines, the valve includes a valve housing, an ejection opening, a magnet winding, a closure element which is connected to an armature associated with the magnet winding, and a pin which is located in the ejection opening and has a conical region, the conical region being within or at a plane formed by the outer edge of the ejection opening. In this way, the formation of drops at the edge of the ejection opening is prevented so that a fine atomization is obtained.
