Definitions

  • the present invention relates to a device for injecting fuel, which can be used in particular in internal combustion engines with direct injection in the stratified charge mode.
  • Devices for injecting fuel for internal combustion engines with direct injection are generally carried out in the prior art as high-pressure injection valves with outwardly opening valve needles, which are actuated by piezo actuators and controlled for the required highly dynamic switching times with complex power amplifiers.
  • High demands on the material quality and manufacturing tolerances of the individual components of these injectors lead to long processing test and production times and the resulting high production costs of these injectors ( WO-A-2005/050001 ).
  • the device according to the invention for injecting fuel with the features of claim 1 has the advantage that this has both a simpler and thus more cost-effective structure, as well as less critical in terms of the required manufacturing and position tolerances of the individual components.
  • a pressure equalizing piston which is arranged on the injection-side part of the valve needle, while a fuel-filled pressure chamber is separated from the first fuel-filled portion of the actuator chamber.
  • the actuator is arranged here in the second fuel-free region of the actuator chamber, a cost-effective electromagnetic actuator can be used, which can achieve the desired highly dynamic switching times. Furthermore, the advantageous use of special soft magnetic materials in the actuator is possible because the actuator components are not exposed to any corrosive effect of the fuel.
  • the pressure compensation piston is slidably disposed with little play in a cylindrical bore of a valve body and provided with a sealing gap.
  • the device according to the invention preferably has a fuel return line from the first region of the actuator chamber to a fuel reservoir.
  • substantially the ambient pressure present in the fuel reservoir is present, which also acts on the side of the diaphragm facing this region.
  • an armature is arranged on the actuator-side part of the valve needle.
  • the actuator comprises a Freiwegfeder whose spring force is designed so that the actuator-side part of the valve needle is always applied to the diaphragm even when not actuated actuator.
  • the return element is designed so that the injection-side part of the valve needle, even when not actuated actuator, d. H. closed valve needle, always applied to the membrane.
  • a lifting of the pressure compensation piston on the membrane and a shock load on the membrane are avoided, which in turn contributes to an increased durability and durability of the membrane.
  • the actuator-side and the injection-side part are always in contact with the membrane in each operating state of the injection device.
  • the injection-side part of the valve needle is formed in two parts with a needle and the pressure compensation piston.
  • a membrane-facing end of the pressure-compensating piston and a membrane facing the end of the actuator-side part of the valve needle are each formed rounded.
  • a homogeneous edition of these ends, in particular in a shifted, d. H. bagged state of the membrane ensured and damage the membrane, z. B. by sharp edges of non-rounded end portions of the pressure compensating piston and the actuator-side part of the valve needle avoided.
  • FIG. 1 a device for injecting fuel according to a preferred embodiment of the invention described in detail.
  • the device 1 for injecting fuel comprises a valve body 2 and an outwardly opening valve needle 3, which is formed from an injection-side part 3a and an actuator-side part 3b.
  • the injection-side part 3a of the valve needle 3 comprises a needle 31 and a pressure compensation piston 10, which are arranged in a pressure chamber 4, the fuel is supplied via a supply line 19 under pressure.
  • the pressure compensation piston 10 is slidably disposed in a cylindrical bore 16 of the valve body 2 with little play.
  • a return element 20 is further arranged, which is supported between the valve body 2 and the needle 31 and the valve needle 3 returns to an initial position after actuation.
  • an electromagnetic actuator 6 is arranged, which comprises a coil 8 and an armature 7, preferably of the type of a flat armature shown here, which is attached to the actuator-side part 3b of the valve needle 3.
  • a diaphragm 13 is further arranged, which is attached to the valve body 2 and on the one hand, the valve needle 3 divided into the injection-side part 3a and the actuator-side part 3b, and on the other hand, the actuator chamber 9 in a first fuel-filled region 5 and a second fuel-free region 18th divided fluid-tight.
  • the first region 5 of the actuator chamber 9 is at least partially filled with fuel which enters the first fuel-filled region 5 via a sealing gap 17 formed on the surface of the pressure-compensating piston 10 as a result of the higher pressure from the pressure chamber 4.
  • an end 10a of the pressure-compensating piston 10 facing the diaphragm 13 and an end 15 of the actuator-side part 3b of the valve needle 3 facing the diaphragm 13 are in each case rounded.
  • damage to the membrane 13 is prevented, which would be caused by possibly formed paragraphs or edges on the end regions of these components during the displacement or buckling of the membrane 13 during actuation of the device 1.
  • a fuel return line 14 branches off from the first fuel-filled region 5 of the actuator chamber 9.
  • a fuel reservoir not shown here, which accumulates through the sealing gap 17 of the pressure compensating piston 10 due to the pressure reduction from the pressure chamber 4 to the first region 5.
  • the fuel return from the first fuel-filled region 5 of the actuator chamber 9 takes place without pressure in the fuel reservoir.
  • the second fuel-free region 18 of the actuator chamber 9 essentially the same pressure is applied to both sides of the membrane 13. Thus, there is a pressure equilibrium on the membrane 13.
  • a free-return spring 12 is further arranged between the armature 7 and a closing element 21 and supports the actuator-side part 3b of the valve spring 3 with the armature 7 fixed thereto at a closing element 21.
  • An electrical connecting line 22 for the actuator 6 is guided through the closing element 21 through to the outside.
  • the freewheeling spring 12 is designed so that the actuator-side part 3b of the valve spring 3 rests against the diaphragm 13 even when the actuator 6 is not actuated.
  • the geometry is designed so that the injection-side part 3a of the valve needle 3 rests against the diaphragm 13 even when the actuator 6 is not actuated (closed valve needle).
