Definitions

  • the invention relates to a fuel injector for a fuel injection system, in particular a common rail injection system, for injecting fuel into the combustion chamber of an internal combustion engine having the features of the preamble of claim 1.
  • the valve body is also accommodated in a valve chamber, which communicates with a control chamber via a first, serving as a drain hole in conjunction with a control chamber and a second, designated as a bypass bore in communication with an inlet channel.
  • fuel can flow into the control chamber via the bypass and the drainage channel in a first closed position of the valve body, so that a rapid closing of the nozzle needle is effected.
  • valve member of the control valve is in this case guided in a sleeve which rests sealingly on a throttle plate separating the valve chamber from the control chamber.
  • the sleeve defines between the valve member and the throttle plate a low pressure space, which leads to a reduction of the hydraulic closing force on the valve member and thus to a pressure relief of the valve member.
  • the required An Tavernditionen or reduced currents.
  • the sleeve has a certain amount of space, so that the valve chamber must have a larger volume.
  • the increased valve chamber volume leads to a delayed pressure build-up both in the valve chamber and in the control chamber, which communicates with the valve chamber via at least one bore formed in the throttle plate.
  • the bore is to be guided in such a way that its mouth region lies outside the sleeve which bears sealingly against the throttle plate.
  • the sealing sleeve may be provided in the contact area with a reduced diameter and / or the valve space with a radial expansion in the mouth area of the bore, wherein a further increase in the valve space volume is unavoidable.
  • a throttle formed in the bore is often arranged in the region of the underside of the throttle plate, that is to say in the vicinity of the control chamber, the valve chamber volume is further increased by the outflow bore adjoining the throttle.
  • Object of the present invention is to develop a fuel injector of the type described above such that the valve chamber volume, especially in the arrangement of the valve member pressure-relieving sealing sleeve is kept as small as possible.
  • the formation of at least one arranged in the throttle plate bore or throttle should be simplified.
  • the proposed fuel injector has a nozzle needle in a hub movable guided nozzle needle for closing and releasing at least one formed in the nozzle body injection port and a control valve for indirect control of the nozzle needle by a valve needle in the closing direction acting control pressure is changed in a control room by opening or closing the control valve ,
  • the control valve in this case comprises a formed in a valve plate valve space which is bounded by a throttle plate which is arranged between the nozzle body and the valve plate and in which at least one bore for connecting the valve chamber with the control chamber and / or a high-pressure channel is formed.
  • the at least one bore opens into the valve space via an axial gap formed between the valve plate and the throttle plate and has a reduced diameter d in the mouth region for forming a throttle whose throttling effect can be influenced via the height h of the axial gap.
  • the throttle point is therefore displaced into the mouth region, so that the bore can be designed such that it has a constant diameter as far as possible.
  • the omission of the outflow bore reduces the valve volume, which in turn leads to a rapid pressure build-up and fast switching times. At the same time, the smallest quantity capability of the fuel injector and also its wear behavior in the area of the valve seat is improved. Because of the smaller valve space volume, the pressure in the valve chamber during the closing of the control valve increases rapidly, so that the remaining pressure stroke and the slippage of the valve in the seat after the impact decrease.
  • the production of the throttle is further simplified. This is now formed in the mouth region of the bore and thus at an easily accessible location on the top of the throttle plate. In addition, an outlet bore adjoining the throttle and / or a diffuser are eliminated. Furthermore, it is possible to dispense with a rounding of the bore in the region of the throttle, so that a further complicated production step is eliminated.
  • the throttling takes place in the mouth region of the bore and can be influenced by the height h of the axial gap between the valve plate and the throttle plate. Because of the throttle effect determining cross section corresponds to the lateral surface of an imaginary cylinder, which arises when the diameter d of the formed in the throttle plate outflow surface is projected onto the opposite surface of the valve plate. The height h of the axial gap corresponds to the height of the cylinder. The desired throttle effect can thus be achieved by establishing the parameters d and h during manufacture.
  • the height h of the axial gap is also chosen to be as small as possible in order to keep the valve space volume small.
  • the height h of the axial gap is preferably ⁇ 500 ⁇ m, preferably ⁇ 100 ⁇ m, more preferably ⁇ 50 ⁇ m.
  • the axial gap between the valve plate and the throttle plate is preferably formed by a primarily radially extending groove in the valve plate. Alternatively or additionally, however, a corresponding recess may also be provided in the throttle plate.
  • the bore formed in the throttle plate connects the valve chamber of the control valve with the high pressure passage and the throttle formed in the mouth region of the bore serves as a filler throttle.
  • the height h of the axial gap is selected such that the fuel flowing out through the bore experiences a counter-pressure, that is to say a pressure counteracting the flow pressure, which reduces the entry of gas bubbles into the valve chamber when the valve is open.
  • the height h of the axial gap is chosen to be less than the height of a radial expansion of the valve space serving as a spout, which is usually about 1 mm.
  • the further bore serving as a drainage channel comprises an outlet throttle, which can be formed in a conventional manner by reducing the flow cross section of the bore in the region of the underside of the throttle plate, that is to say in the vicinity of the control chamber. At the throttle point is then followed by a long, the valve space volume magnifying discharge hole.
  • the bore formed in the throttle plate connects the valve space to the control chamber and the throttle formed in the mouth region of the bore serves as an outlet throttle.
  • the advantages described above in connection with the bore having the filling throttle now apply correspondingly to the bore serving as a drainage channel. This means that the hole is easy to produce due to its largely constant diameter.
  • the displacement of the throttle point in the mouth area also simplifies the formation of the throttle, which is now arranged at the top of the throttle plate and makes a long outflow bore and / or a diffuser dispensable.
  • a further, correspondingly formed bore or throttle for connecting the valve chamber to the high-pressure passage can be provided so that further a fast filling of the valve space volume and thus a rapid pressure build-up in the control chamber is ensured.
  • At least one bore provided in the throttle plate is formed to be hydroerosive rounded at least in a partial region. This measure proves to be particularly advantageous if the flow of a throttle scatters too much.
  • the rounding is preferably carried out in the assembled state with associated valve plate.
  • control valve comprises a cooperating with a valve seat liftable valve member whose valve seat opposite end is guided in a sealingly adjacent to the throttle plate and a low pressure space limiting sleeve, so that the valve member is relieved of pressure in contact with the valve seat. Because by the leadership of the valve member in such a sealing sleeve, the hydraulic closing force is reduced to the valve member. This in turn leads to a reduction of the switching forces and concomitantly to a reduction of the required drive voltages or currents.
  • sealing sleeve usually requires an enlarged valve chamber volume
  • advantages of the invention, in particular in a control valve with such a sealing sleeve come into play. Because the interaction of the throttle plate formed bore with the formed in the valve plate axial gap is able to compensate for at least a portion of the valve space enlargement.
  • the limited by the sleeve low pressure space is connected via a bore to a return.
  • the the low pressure chamber with a return connecting hole is at least partially also formed in the throttle plate.
  • a piezoelectric actuator is provided for actuating the control valve.
  • Fig. 1 is a section of an already known fuel injector refer.
  • the detail shows the fuel injector in the region of a throttle plate 7 including adjacent components.
  • the latter include a nozzle body 1, which is attached in the drawing from below to the throttle plate 7 and the recording of a liftably guided nozzle needle 2 for releasing or closing at least one nozzle opening formed in the injection orifice 1, and a valve plate 5, in the drawing from above is attached to the throttle plate 7 and the recording of a control valve 3 for indirect control of the nozzle needle 2 is used.
  • the control valve 3 has a valve space 6 which can be connected to a return 20 and which is furthermore connected to a control chamber 4 via a bore 12 designed as a drainage channel.
  • Control chamber 4 is in turn via an inlet channel 21 in hydraulic communication with a high pressure passage 9, so that a filling of the control chamber 4 is ensured with fuel with the control valve 3 closed.
  • the fuel flowing into the control chamber 4 via the inlet channel 21 causes an increase in the control pressure existing there, which acts on the nozzle needle 2 in the closing direction.
  • the nozzle needle 2 completes a closing movement or is held in its closed position. If the control valve 3 is opened, wherein a compound of the valve chamber 6 is prepared for return 20 and a Abêtmenge the return 20 is supplied, it comes in the valve chamber 6 and the control chamber 4 to a pressure drop, which allows an opening stroke of the nozzle needle 2.
  • the actuation of the control valve 3 takes place here by using a piezoelectric actuator, which lifts a valve member 16 of the control valve 3 from its valve seat 15 during energization and thus establishes the connection of the valve chamber 6 to the return line 20.
  • the valve member 16 is presently guided in a sleeve 18 which rests sealingly against the throttle plate 7 and a low-pressure chamber 17 radially limited. Through a bore 19 of the low-pressure chamber 17 is in communication with the return 20. Due to the fact that the valve seat facing away and absorbed in the sleeve 18 end of the valve member 16 is not high pressure, the valve member 16 is depressurized.
  • the actuation of the control valve therefore requires lower switching forces, that is, lower drive voltages or drive currents. This has an advantageous effect on the design of the piezoelectric actuator as an actuating means.
  • a further bore 8 is provided in the throttle plate, which the valve chamber. 6 connects directly to the high pressure channel 9.
  • the bores 8, 12 and 21 each have a reduced flow cross-section in the region of the underside of the throttle plate 7.
  • the reduced flow cross section is followed in each case by a long outlet bore, which opens into the valve chamber 6 in the region of a radial widening, that is to say a spout.
  • Both the long outflow holes, as well as the volume of the Schnaupen contribute to an undesirable increase in the volume of the valve chamber 6.
  • the disadvantage of an enlarged valve space volume due to the use of a sleeve 18 for pressure relief of the valve member 16 is compensated by the fact that the throttle 11 of the bore 8 has been moved into the mouth region of the bore 8. A long the valve chamber 6 enlarging discharge hole thus eliminated. Furthermore, the spout has been replaced by an axial gap 10 between the valve plate 5 and the throttle plate 7, over the height h of the throttle effect can be influenced. The axial gap 10 thus forms a part of the throttle 11.
  • the serving as a drain passage bore 12 is in the embodiment of Fig.
  • a throttle 14 which is formed in the lower region of the bore 12 and to which a long outflow bore connects.
  • a throttle 14 which is formed in the lower region of the bore 12 and to which a long outflow bore connects.
  • Alternatively, however, also serving as a drain passage bore 12 may be formed according to the bore 8 with a throttle 14 in the mouth region.
  • FIG. 3 Another alternative embodiment of serving as a drain passage bore 12 goes out of the in Fig. 3 illustrated embodiment of a fuel injector according to the invention.
  • the height h is selected such that a back pressure is applied to the outflowing fuel.
  • the back pressure should reduce the entry of gas bubbles in the valve chamber 6.
  • the axial gap 13 has a height h which is opposite to the height of the in Fig. 1 shown spout is significantly reduced, so that a reduction of the valve chamber volume is achieved.
  • the height h of the axial gap 13 is greater than the height h of the axial gap 10 chosen, since within the bore 12 is already formed a flow restrictor 14 for throttling the fuel flow.
