摘要： A needle type fuel injector has a needle control chamber at a pressure subject to a control valve in a control valve chamber which in an opening phase is lifted from its seat to expose the control valve chamber, connecting passage, and needle control chamber to a low pressure drain and in a closing phase is urged against the seat to isolate the control valve chamber, connecting passage, and needle control chamber from the drain. The potential for cavitation at high fuel injection pressure is reduced by throttling the flow of fuel past the control valve seat when the control valve opens, thereby maintaining sufficient back pressure in the control valve chamber and upstream connecting passages.

摘要： A programmable diesel fuel injector that increases frequency response and control precision over desired fuel flow rates throughout each injection event. All valve frequency and motional requirements are met by a compensated direct drive, which is enabled by the durable capability of a rare earth alloy to lengthen in a magnetic field. A continuously variable electrical input waveform is predetermined to result in the desired fuel injection rate shape. A magnetostrictive transducer converts voltage and current into continuously variable force and displacement of a master piston acting upon fuel within a closed chamber. A slave piston responds to the fuel pressure changes within the closed chamber and acts upon the spool of a spool valve to eject fuel.

摘要： An electromagnetically actuatable valve, e.g., a fuel injector for fuel injection systems, includes an electromagnetic actuating element having a solenoid, a fixed core, a valve jacket, and a movable armature for actuating a valve closing body, which cooperates with a valve seat surface provided on a valve seat body. In addition, the valve has a restoring spring for resetting the valve closing body to its resting position on the valve seat surface. The restoring spring and an internal longitudinal bore hole of the armature are paired in such a way that the armature is guided during its axial movement only along the restoring spring.

摘要： A fuel injection valve is characterized in that a multi-fan stream nozzle is shaped, downstream from a fixed valve seat that is provided on the inner wall of a valve sleeve, directly into the valve sleeve itself. The multi-fan stream nozzle is integrated directly in the region of a bulge formed at the downstream end of the valve sleeve. The multi-fan stream nozzle, serving as an atomization device, possesses a plurality of slit-shaped spray openings, so that from the sheets of liquid emerging from the spray openings, sheet packets are formed in which individual sheets of liquid extend divergently from one another. Introduction of the spray openings into the deep-drawn valve sleeve is effected using ultrashort-pulse laser technology. The fuel injection valve is suitable in particular for use in fuel injection systems of mixture-compressing spark-ignited internal combustion engines.
