Definitions

  • the invention relates to a fuel injector of a fuel injection system of an internal combustion engine, wherein the fuel injector comprises a hydraulic coupler having a movable in a coupler body coupler piston and a coupled thereto via a coupler gap also movable in the coupler body working piston, and wherein the coupler gap via at least one filling channel with a is connected outside the coupler body arranged low pressure space.
  • Such a fuel injector is from the DE 10 2009 001 266 A1 known.
  • This fuel injector of a common rail fuel injection system has a hydraulic coupler which has a coupler piston movable in a coupler body and a piston which is also coupled to it in the coupler body via a coupler gap.
  • the coupler gap is connected via a filling channel with a arranged outside the coupler body low pressure space.
  • This filling channel is arranged in the coupler body, that the filling channel is closed during a downward movement of the coupler piston, while the filling channel is opened during an upward movement of the coupler piston.
  • a fuel injection device with a hydraulic coupler in which two coaxially arranged coupling pistons limit a fillable via a connecting line filling space.
  • the invention has for its object to provide a fuel injector with a coupler, wherein the filling of the coupler gap space is improved with hydraulic fluid.
  • This object is achieved in that in the region of a connection of the filling channel with the Kopplerspaltraum an opening in the direction of the coupler gap, one-piece and elastically formed valve is arranged.
  • This embodiment is based on the finding that with each switching operation in the coupler, a significantly higher pressure than in the surrounding low-pressure space arises. This results in the games on the piston guides of the coupler piston and the working piston in the coupler body to a leakage from the coupler, more precisely from the Kopplerspaltraum out.
  • a hydraulic coupler has a speed limit, with which it can be operated at a required number of injections in dependence on the pressure of the fuel.
  • the inventive design of the coupler a significantly improved refilling is achieved, which significantly improves the speed resistance of the coupler.
  • the valve is designed as an axially slotted sleeve.
  • Such axially slotted sleeve is easy to manufacture and also has a high closing accuracy of the filling channel.
  • the valve or the slotted sleeve is a leaf spring valve.
  • This leaf spring valve is very first simply constructed and also extremely durable by a very small adjustment. Furthermore, only a very small dead volume is shown by the design of the valve as a leaf spring valve and the arrangement of the leaf spring valve within the coupler body. Furthermore, by a good fit of the leaf spring valve in the coupler body to close the filling channel of the coupler gap space, if any, increased only very slightly, which is why the coupler function over other known solutions is improved.
  • the diameter of the leaf spring valve is greater than the inner diameter of the coupler body in the region of the mouth of the filling channel in the coupler gap. Because of this slightly larger outer diameter of the leaf spring valve than the inner diameter of the coupler body and the radially resilient properties, the leaf spring valve is against the inner wall of the coupler body at a higher pressure in the coupler gap than in the low pressure chamber and thus reliably seals the filling channel.
  • an actuator of the fuel injector is actuated, a movement of the coupler piston into the coupler gap space results in an immediate buildup of pressure in the coupler, which, as described above, improves the function of the coupler.
  • a securing device for fixing the leaf spring valve is provided.
  • This safety device is generally designed so that the leaf spring valve is neither radially nor axially in relation to the mouth of the filling channel in particular during operation of the fuel injector can move. This ensures that a possible failure of the coupler is excluded by a no longer be shut off by the leaf spring valve filling channel.
  • the securing device is an anti-rotation device.
  • Such anti-rotation device is usually sufficient for trouble-free operation of the coupler.
  • the anti-rotation device is in a retaining groove of the coupler piston (or the coupler body) engaging the fold of the leaf spring valve.
  • the rotation can also be formed by a separate component in the form of, for example, a metal sheet, which cooperates with the coupler piston (or the coupler body), so that the leaf spring valve can not rotate.
  • the anti-rotation device is a nose which cooperates with a recess either in the coupler body or else with a corresponding design of the recess in the coupler piston.
  • the material of the leaf spring valve spring steel This is the most suitable material for producing the leaf spring valve.
  • FIG. 1 shows a fuel injector 1 of a common rail injection system for injecting fuel into a combustion chamber, not shown, of an internal combustion engine.
  • a high-pressure pump 2 conveys fuel from a tank 3 into a high-pressure accumulator 4.
  • fuel in particular diesel fuel
  • the high-pressure accumulator 4 of the fuel injector 1 is connected in addition to other, not shown fuel injectors via a high pressure line 5.
  • the high-pressure line 5 opens into an axial supply channel 6 belonging to a high-pressure region of the fuel injector 1, through which fuel flows into a pressure chamber 7.
  • the fuel flows from the pressure chamber 7 in the axial direction past an injector needle 8 through injection bores 16 into the combustion chamber of the internal combustion engine.
  • the fuel injector 1 is connected via an injector return port 9 to a return line 10.
  • a control quantity of fuel Via the return line 10, a control quantity of fuel, which will be explained below, can flow away from the fuel injector 1 to the tank 3 and from there can again be supplied to the high-pressure circuit.
  • the injector needle 8 is guided axially adjustable within a stepped bore 11 of an injector needle body 12.
  • the injector needle body 12 is clamped in conjunction with a throttle plate and a valve body against a holding body 13 by means of a clamping nut.
  • the Injektornadel 8 has at its needle tip 15 designed as a sealing surface closing surface with which the Injektornadel 8 is mounted in a tight contact with a trained within the Injektornadel stressess 12 Injektornadelianusitz. If the Injektornadel 8 rests against the Injektornadelianusitz, so is in the closed position, the fuel outlet from the at least one injection hole 16 is locked. By contrast, if the injector needle 8 is lifted off the injector needle body seat, fuel can flow from the pressure chamber 7, which is at least approximately under the pressure of the fuel in the high-pressure accumulator 4, into the combustion chamber.
  • a control chamber 17 is limited, which is supplied via an inlet throttle 18 with fuel under high pressure from the supply channel 6.
  • the pressure chamber 14 encloses a control chamber 17 limiting, spring-loaded sleeve body 32 radially outward.
  • the formed in the sleeve body 32 control chamber 17 is connected via an outlet throttle 19 with a control valve chamber 20 which is connected by means of an axially adjustable control valve element 21 with a low-pressure chamber 22 and thus with the injector return port 9.
  • the control valve element 21 is part of a normally designed as a 3/2-way valve control valve 23.
  • a first (lower) switching position befindettess control valve element 21, fuel from the control chamber 17 via the outlet throttle 19 and the control valve chamber 20 in the low pressure chamber 22 to the injector return port stream.
  • a bypass 35 opening out of the pressure chamber 14 and opening into the control valve chamber 20 is blocked by the control valve element 21.
  • befindliches control valve element 21 When in a second (upper) switching position befindliches control valve element 21, the connection between the control valve chamber 20 and the low-pressure chamber 22 is locked and the bypass 35 is released, so that the control chamber 17 via the bypass 35, the control valve chamber 20, the outlet throttle 19 and the inlet throttle 18 is brought quickly to high pressure.
  • a piezoelectric actuator 24 is provided, which is coupled via a hydraulic coupler 25 with the control valve element 21.
  • the control valve 23 can be actuated directly by the hydraulic coupler 25, more precisely by a working piston 28 of the hydraulic coupler 25 which will be explained below.
  • the piezoelectric actuator 24 is energized and expands.
  • the working piston 28 presses on the control valve element 21, which is moved away in the sequence counter to the force of a control closing spring 30 from its upper control valve seat 26 and thus releases the flow of fuel from the control chamber 17 to the injector return port while blocking the bypass 35.
  • a control closing spring 30 By adjusting the flow cross-sections of the pressure in the control chamber 17 decreases rapidly, whereby the injector needle 8 lifts from her Injektornadel stresses so that fuel can flow out of the pressure chamber 7 through the injection hole 16.
  • the energization of the piezoelectric actuator 24 is terminated, whereby the piezocrystal stack of the actuator 24 contracts and the coupler piston 27 is supported by the spring force of a Bourdon tube 38 in the drawing plane moves upward.
  • the working piston 28 presses supported by the control closing spring 30 in the plane of the drawing down against the control valve element 21. Between the working piston 28 and the control valve element 21 thus a permanent contact is ensured.
  • the working piston 28 and the control valve element 21 are moved at not energized actuator 24 upwards into the upper switching position in which the control valve element 21 rests against its upper control valve seat 26 and the hydraulic connection from the control chamber 17 to Injector return port 9 locks.
  • the fuel flowing in through the inlet throttle 18 and via the bypass 35 into the control chamber 17 ensures a rapid pressure increase in the control chamber 17 and a hydraulic closing force acting on the injector needle 8.
  • the resulting closing movement of the Injektornadel 8 is supported by a closing spring 31 which is supported at one end to the Injektornadel 8 and the second end to a control chamber 17 limiting sleeve body 32.
  • FIGS. 2 to 4 show the detailed configuration of the coupler 25 with the arranged in a stepped recess 34 in a coupler body 33 coupler piston 27 and working piston 28 in different switching positions.
  • the coupler piston 27 has a larger outer diameter than the working piston 28 and is thus arranged in the stepped recess 34 with the larger inner diameter.
  • the coupler piston 27 may also have a same or smaller diameter than the working piston 28.
  • the coupler piston 27 protrudes with an actuation-side end, on which an actuation plate 36 is arranged, out of the coupler body 33 and cooperates with the actuator 24 by means of the actuation plate 36.
  • the working piston 33 has an actuating nose 37, which - as described above - the control valve element 21 from the control valve seat 26 down ( FIG. 1 ) can press.
  • the coupler 25 has a Bourdon tube 38 which is supported on a lower annular shoulder 39 of the coupler body 33 and the actuator plate 36 and presses apart the two components.
  • a retaining ring for a working piston spring 40 is arranged on the working piston 28, which presses the working piston 28 down from the coupler body 33 to the abutment of the actuating lug 37 on the control valve element 21.
  • a filling channel 41 in the Wall of the coupler body 33 inserted is preferably a filling channel 41 in the Wall of the coupler body 33 inserted.
  • the filling channel 41 is closed in the region of an orifice in the coupler gap 29 by a one-piece and elastically deformable valve opening in the direction of the coupler gap 29 in the form of a leaf-spring valve 42 designed as a slotted sleeve.
  • the leaf spring valve 42 has a slightly larger outer diameter than the inner diameter of the coupler body 33 and the step recess 34. Due to the slightly larger outer diameter of the leaf spring valve 42 and the radially resilient properties of the leaf spring valve 42 abuts the stepped recess 34 and seals the hydraulic connection through the filling channel 41 from.
  • the valve is closed ( FIG. 2 ).
  • the leaf spring valve 42 is arranged in the region of a stepped shoulder 43 of the coupler piston 27, which saves space and has no effect on the function of the coupler 25. With regard to the arrangement of the leaf spring valve 42 but other solutions are conceivable.
  • FIG. 6 shows a basically same construction of the coupler 25 with a coupler piston 27, as has been previously described.
  • a securing device 44 is provided here, which ensures that the leaf spring valve 42 in particular does not rotate and thus reaches the region of the mouth of the filling channel 41 with a slot 45 (the slotted sleeve). In such a case, the function of the leaf spring valve 42 would not be ensured.
  • the securing device 44 is formed as an angled sheet, which is clamped to the stepped shoulder 43 of the coupler piston 27 in a suitable manner.
  • the securing device 44a may also be formed by a fold 46 of the leaf spring valve 42 at an end adjoining the slot 45.
  • the fold 46 which may also be connected to the leaf spring valve 42, for example, welded, part engages in a retaining groove 47 in the coupler piston 27 a.
  • the securing device may also be a nose, which engages in a corresponding depression in the coupler piston 27. Basically, the rotation of the leaf spring valve 42 can also take place relative to the coupler body 33.
