  • a nozzle spring is provided which the nozzle needle in Direction to her sealing seat pretensions.
  • the pressure in the Pressure chamber is dependent on the opening position of the electromagnetic Valve controlled. If the valve is open, so fuel flows out of the pressure chamber via the outlet throttle from and at the same time less fuel flows through the inlet throttle too, so that the pressure in the control chamber drops.
  • the nozzle needle in the direction of the nozzle chamber moves, with the nozzle needle with its tip of a Sealing seat lifts off and a connection between the fuel line and injection holes releases.
  • the injection valve described has the disadvantage that the nozzle spring is in the control chamber and thus a relatively large control chamber is necessary, which is a large Represents harmful volume. Furthermore, by installing the Nozzle spring in the control chamber at risk Installation dirt particles enter the control chamber and themselves in the outlet throttle and the operability of the injection valve. Cavitation bubbles, the in the inlet throttle, can damage the nozzle spring.

  • control chamber bounded by a control piston is, via a rod with the nozzle needle in operative connection stands.
  • the rod is guided through a chamber, in a needle spring for biasing the nozzle needle is arranged.
  • the control chamber is free of moving parts, causing contamination of the control chamber is excluded by introduced components. moreover the control chamber can be carried out particularly lead, whereby reduces the dead volume bein driving the nozzle needle is.
  • the cross section of the control piston is preferably equal to Cross-section of the guided portion of the nozzle needle formed. In this way, only one guide is to be made, thereby the injection valve is inexpensive.

  • In the injection chamber 31 is a second sealing seat 21st arranged, with the closed state, a nozzle needle 32 rests with a needle tip 19.
  • the needle point 19 is in communication with a guide portion 18 which is in Shape of a cylinder is formed.
  • the guide portion 18 is in a guide bore 33 of the Injection valve guided longitudinally movable.
  • the guide hole 33 is in the form of a cylindrical recess in the housing 29 introduced.
  • the guide bore 33 opens on a Side in the nozzle chamber 20 and on the other side in one Through hole 34, which is also cylindrical is and preferably a smaller cross section than the Guide bore 33 has.
  • grooves 40 are provided, which connect the nozzle chamber 20 with the chamber 25.
  • the through hole 34 in turn opens into a chamber 25, which is also cylindrical and a larger Cross-section than the guide bore 33 has.
  • a coupling piece 35 is arranged on the guide portion 18 rests.
  • a Coupling rod 17 is arranged, which with a plate 23 on the Coupling piece 35 rests.
  • the plate 23 is circular and has a larger cross-section than the cylindrical one Coupling rod 17 on.
  • the plate 23 has the function a support collar for the needle spring 24.
  • the guide 18 of the nozzle needle also completely omitted, leaving a circular cavity between Nozzle needle 32 and housing 29, the nozzle chamber 20 with the Chamber 25 connects. Furthermore, the chamber 25 also has a Connecting line 26 is connected directly to the high-pressure line 11 become.
  • the chamber 25 opens on the side of the through hole 34 is opposite, in a second guide bore 36th Die second guide bore 36 also has a cylindrical shape on.
  • a cylindrical Control piston 16 arranged to be movable in the longitudinal direction, which is connected to the coupling rod 17. Between the top End of the control piston 16 and the housing 29 is in the second guide bore 36 a control chamber 15 is formed.
  • a needle spring 24 is arranged, which is the Coupling rod 17 includes and between the plate 23 and a Step 37 is arranged, wherein the step 37 in the transition region between the chamber 25 and the second guide bore 36 is arranged.
  • the second guide bore 36 has a smaller diameter than the chamber 25.
  • the functioning the needle spring 24 is that the needle spring 24, the nozzle needle 32 with the needle tip 19 on the second Tight fit 21 pretensioned.
  • the chamber 25 is preferably over a connecting line 26 to the fuel line 11th connected.
  • the control chamber 15 is connected via an inlet throttle 13 with the Fuel line 11 and an outlet throttle 14 with a Valve chamber 9 in conjunction.
  • the cross section of the inlet throttle 13 is smaller than the cross section of the outlet throttle 14th
  • In the valve chamber 9 is a closing member 6 and a valve spring 8, wherein the closing member 6 of the valve spring 8 is biased in the direction of a sealing seat 7.
  • the closing member 6 and the sealing seat 7 provide a servo valve 5 dar.
  • the valve chamber 9 is above a drain hole 38 with a return 40 in conjunction.
  • one is Bypass throttle 12 is provided in the form of a bore, which is the Fuel line 11 connects to the valve chamber 9.

  • In the drain hole 38 is a valve piston 4 is guided, which is connected to an actuator 3 is.
  • the valve piston 4 is located with a pressure surface on a associated pressure surface of the closing member 6.
  • the actor 3 is via electrical connections 2 with
  • the injector works as follows: In the fuel tank 10 is fuel at high pressure, so that in a closed servo valve 5, wherein the closing member 6 abuts the sealing seat 7, in the valve chamber 9, in the Control chamber 15, in the nozzle chamber 20, in the injection space 31st and in the chamber 25 high-pressure fuel is present is. Since the area with which the control piston 16 to the control chamber 15, larger than the area covered by the Nozzle needle 32 with pressure in the direction of the control chamber 15th is applied and additionally the biasing force of the needle spring 24, the nozzle needle 32 presses on the sealing seat 21, sits the nozzle needle 22 on the sealing seat 21 and separates the Injection space 31 from the injection holes 22. Thus takes place no injection.

  • the fuel flows via the outlet throttle 14 in the valve chamber. 9 and on via the drain hole 38 in the return line 27 to a fuel reservoir.
  • the pressure drops in the control chamber 15.
  • the pressure in the nozzle chamber 20 remains continue at the level of the fuel line 11.

As a result, a particularly low-friction movement of the nozzle needle 32 possible. In addition, leakage occurs via the chamber 25 towards the control chamber 15 only when the servo valve 5 is open and a slight pressure in the control chamber 15 prevails. Furthermore, the connection of the chamber 25 to the Fuel line 11 has the advantage that the guide fit between the guide portion 18 and the guide bore 33rd do not have to be as precise as there is no sealing between the nozzle chamber 20 and the chamber 25 is necessary. This allows a cost saving in the production of the injection valve.
  • the resulting chamber can be used as a drain line used to connect the high pressure line via the bypass throttle to connect with the outlet of the outlet throttle.
