- the tubular spring 17 By means of the tubular spring 17, the support disk 11 is set in its rest position when the energization of the piezocrystal stack of the actuator 39 is canceled.
- the tubular spring 17 between the support plate 11 and the upper end surface 7 of the washer 3 surrounds a stop sleeve 18.
- the stop sleeve 18 extends below a shoulder of the second booster piston 14 and surrounds a spring 28, a control chamber 25 defining a first control chamber sleeve 27 to the upper Plane 7 of the washer 3 of the fuel injector 1 hires.
- the spring 28 is permanently tensioned due to the pressure prevailing in the cavity 9 fuel pressure, so that it is ensured that the first control chamber sleeve 27 is always employed with its formed on the underside biting edge 29 against the upper end face 7 of the washer 3, so that the STEU ⁇ Erraum 25 is sealed.
- control chamber 25 From the control chamber 25, the fuel contained in this and corresponding to the retraction movement of the first booster piston 13 and the second booster piston 14 or both pistons in the control chamber 25 corresponding compressed over the channel 26 flows below the lower end surface 8 of the washer 3 hydraulic space, the one head 31 of the needle-shaped Injektventil ⁇ member 6 hydraulically acted upon.

- the hydraulic space between the lower planar surface 8 of the intermediate disc 3 and the upper end face of the needle-shaped injection valve member 6 is delimited by a second control chamber sleeve 32.
- the second control chamber sleeve 32 in turn is acted upon by a spring 33, which is supported on a support ring 34 which can be shrunk onto the peripheral surface of a needle-shaped injection valve member 6, ie by means of a press fit with the lateral surface of the needle-shaped injection valve member 6 connected is.
- a support ring 34 which can be shrunk onto the peripheral surface of a needle-shaped injection valve member 6, ie by means of a press fit with the lateral surface of the needle-shaped injection valve member 6 connected is.

- the piezocrystal stack of the actuator 39 is energized and thus elongated in the vertical direction. Accordingly, the support plate 11 is deflected in the vertical direction downwards and acts on the tube spring 17, so that it is biased against the vertical stroke direction of the actuator 39. Due to the energization of the piezocrystal stack of the actuator 39, both the first booster piston 13 and the second booster piston 14 of the multistage pressure booster 12 are retracted into the control chamber 25. In this, therefore, there is an increased pressure which acts on the hydraulic space above the Kop ⁇ fes 31 of the needle-shaped injection valve member 6 via the channel 26 in the washer 3.
- the piezocrystal stack of the actuator 39 contracts and its elongation in the vertical direction decreases. Due to the pre-tensioned tubular spring 17, the support disk 11 moves in the vertical direction in accordance with the Reduction of the elongation of the piezocrystal stack of the actuator 39 upwards, so that the first booster piston 13 with its the control chamber 25 facing end face 23 exit from the control chamber 25, whereby there the pressure decreases.

- d 3 denotes the outer diameter of ver ⁇ displaceably movable on the first booster piston second booster piston 14.
- a complete opening of the needle-shaped injection valve member 6 can be achieved by a small actuator stroke by moving a larger hydraulic surface (23 +24), which is important in the full load range of the internal combustion engine. If, however, the crystal stack of the piezoelectric actuator 39 is energized again, then an elongation of this crystal stack corresponding to the energization level of the piezocrystal stack sets in, whereby the support disk 11 is compressed against the action of the tubular spring 17, which is supported on the upper planar surface 7 of the intermediate disk 3.
- the tube spring 17 surrounds the stop sleeve 18, which in turn engages with its upper edge a shoulder on the outer circumference of the second booster piston 14 and defines its basic position.

- the fuel volume flowing in the flow direction 38 flows to the injection openings formed at the combustion chamber end of the fuel injector 1 and, via this, when the injection valve member 6 is open or only partially opened, enters the combustion chamber of the self-igniting internal combustion engine.
- the proposed solution according to the invention is characterized in particular by the fact that in the first Generalhub Siemens the needle-shaped injection valve member 6 opening the needle-shaped injection valve member with a high rigidity, effected by the small ratio of 1: 1-1.5, realized between Aktorhub and injection valve member can be.
- the opening of the injection chamber arranged on the combustion chamber side in the first partial lift region of the injection valve member is controlled, ie, occurring due to the needle-shaped injection valve member 6 opening too fast Volume jumps with regard to the amount of fuel introduced into the combustion chamber are avoided, so that the production of soot in combustion recedes to a considerable extent.
