Definitions
- control chamber is delimited by a sleeve which can be displaced under sealing action at the end of the nozzle needle remote from the combustion chamber and is held in contact with the injector housing with the aid of the nozzle spring.
- the sleeve provides the advantage that the control chamber and the nozzle spring chamber can be combined at the end of the nozzle needle remote from the combustion chamber, without the volume of the control chamber depending on the installation space of the nozzle spring. Therefore it is possible to use a nozzle spring with a high
- the injection time and the injection time can be precisely defined.
- the control room can be made very small, which leads to a quick response of the injector according to the invention.
- the nozzle needle diameter In order to achieve higher nozzle needle speeds, which is particularly important when closing the needle, the nozzle needle diameter must be reduced. A needle diameter of less than 3.5 mm is necessary for a closing speed of 1 m / sec with an acceptable control quantity. This is technically very complex and therefore expensive. According to the present invention, the
- Nozzle needle diameter can be chosen freely and is not dependent on the dimensions of the nozzle spring.
- the length can be considerably reduced compared to conventional nozzle needles, which contributes to an exact stroke stop.
- a special embodiment of the invention is characterized in that a biting edge is formed on the surface of the sleeve which is in contact with the injector housing. It is thereby achieved that the control chamber formed in the interior of the sleeve surrounding nozzle spring chamber remains separate.
- Another special embodiment of the invention is characterized in that the inner diameter of the sleeve is less than or equal to a guide diameter on the nozzle needle.
- the inner diameter of the sleeve and the corresponding outer diameter on the nozzle needle can be made much smaller than in conventional injectors.
- a further special embodiment of the invention is characterized in that the fuel supply is connected to the pressure chamber via the nozzle spring chamber and that the nozzle needle is guided between the nozzle spring chamber and the pressure chamber.
- a further special embodiment of the invention is characterized in that at least one flat surface is formed on the nozzle needle between the nozzle spring chamber and the pressure chamber, which fuel can pass from the nozzle spring chamber into the pressure chamber.
- This type of construction offers advantages in particular with regard to high-pressure strength.
- Further special embodiments of the invention are characterized in that the inlet throttle is integrated in the nozzle needle, the sleeve or the injector housing. The inlet throttle serves to prevent pressure surges during operation.
- a further special embodiment of the invention is characterized in that the sleeve has a collar at its combustion chamber end.
- the collar forms a first abutment for the nozzle spring.
- Another particular embodiment of the invention is characterized in that a step is formed on the nozzle needle, which step forms a stop for a spring plate.
- the spring plate forms a second abutment for the nozzle spring.
- Another special embodiment of the invention is characterized in that a circumferential groove is recessed in the nozzle needle, in which a retaining ring is supported, which forms a stop for a spring plate.
- the outer diameter of the nozzle needle in the control chamber and the guide diameter of the nozzle needle between the nozzle spring chamber and the pressure chamber can be the same size. This is in manufacturing, e.g. by
- Another special embodiment of the invention is characterized in that the retaining ring is in two parts and is fixed in the assembled state by the spring plate. This prevents the spring plate from loosening in operation in a simple manner.
- nozzle needle stroke is defined by the distance between the sleeve and the spring plate is.
- This purely mechanical nozzle needle stroke end stop provides the advantage that the nozzle needle stroke is exactly reproducible. This can reliably shaped ground 'of the injection process. So-called hydraulic gluing is avoided.
- Stop for the spring plate or between the nozzle spring and the abutments for the nozzle spring are arranged. The closing behavior of the injector can thereby be improved.
- Another special embodiment of the invention is characterized in that the nozzle needle stroke is defined by the distance between the end surface of the nozzle needle remote from the combustion chamber and the injector housing.
- This embodiment has the advantage that it is particularly easy to implement in terms of production technology.
- a further special embodiment of the invention is characterized in that recesses are provided in the end surface of the nozzle needle remote from the combustion chamber and / or in the opposite surface of the injector housing, the dimensions of which are adapted to the volume of the control chamber.
- Figure 1 shows a first embodiment in longitudinal section through the injector with a bore between the nozzle spring chamber and the pressure chamber.
- Figure 2 shows a second embodiment in longitudinal section through the injector with a flattening on the nozzle needle between the nozzle spring chamber and the pressure chamber.
- FIG 3 shows a further exemplary embodiment in a longitudinal section through the injector, the inlet throttle being integrated in the nozzle needle or in the injector housing;
- Fig. 5 shows a variant of the embodiment shown in Fig. 4 with a two-part
- Fig. 6 is a sectional view taken along the line VI-VI in Fig. 5;
- FIG. 7 shows a further embodiment in longitudinal section through the injector with spacer elements for setting the nozzle needle stroke and the nozzle spring pretensioning force
- FIG. 8 shows a further exemplary embodiment in longitudinal section through the injector with cross grooves in the end face of the nozzle needle remote from the combustion chamber;
- the control chamber 30 is connected to the nozzle spring chamber 20 via an inlet throttle 31.
- the control chamber 30 is connected to a relief chamber (not shown) via an outlet throttle 32.
- connection of the control chamber 30 to the relief chamber depends on the position of a control valve member 33.
- the injector shown in Fig. 1 works as follows
- High-pressure fuel reaches the nozzle spring chamber 20 via the fuel inlet 21. From there, the high-pressure fuel reaches the control chamber 30 via the inlet throttle 31 and the pressure chamber 24 via the bore 23.
- the diameter ratios are selected in a known manner that the nozzle needle 8 is due to the high pressure in the control chamber 30 with its tip 9 in contact with the nozzle needle seat.
- the control valve member 33 opens, the control chamber 30 is relieved of pressure and the nozzle needle tip 9 lifts off its seat.
- High-pressure fuel is then injected into the combustion chamber of the internal combustion engine through the spray holes 10 and 11 until the control valve member 33 closes again. This then has the consequence that the pressure in the control chamber 30 rises again and the nozzle needle 8 is pressed with its tip 9 again against the associated nozzle needle seat.
- the second exemplary embodiment shown in FIG. 2 largely corresponds to the first illustrated in FIG. 1 o rH
- two grooves 55 and 56 are arranged crosswise in the end face 54 of the nozzle needle 8.
- a purely mechanical stop of the needle nozzle is thereby achieved. If the dimensions of the grooves 54 and 55 are adapted to the injector, this can become a "semi-hydraulic stop".
- the breakthrough cross section remaining at the stop is chosen to be just large enough to prevent the nozzle needle 8 from oscillating, but to reduce the amount of control at the end stop as much as possible.
- a throttle bore 58 is arranged in the end face 54 of the nozzle needle 8 parallel to the longitudinal axis of the nozzle needle 8.
- Throttle bore 58 opens into a bore 59 which extends transversely to the longitudinal axis of the nozzle needle 8.
- the bore 59 is a blind bore which is open towards the end of the nozzle needle 8 which is distant from the combustion chamber and is frustoconical.
- a groove 61 is cut out in the opposite surface 62 of the valve body 3 instead of in the end face 54 of the nozzle needle 8 remote from the combustion chamber.
- the groove 61 has the same function as the grooves 54 and 55 in the embodiment shown in FIGS. 8 and 9.
