Definitions

  • the invention relates to a force-balanced control valve for controlling a fuel injector of an internal combustion engine according to the preamble of claim 1.
  • a force balanced control valve for a fuel injector is off EP 1 612 403 A1 known in which on a guide pin of a valve member, a valve sleeve is guided axially movable.
  • the valve sleeve defines a valve chamber to the outside, which is connected to a control chamber of a nozzle needle of the fuel injector via a drain hole.
  • a closing spring By a closing spring, the valve sleeve is pressed against a valve seat formed on the valve seat and thereby closes the valve chamber to the outside.
  • the valve sleeve is moved by an electromagnetic actuator and thereby operated balanced force, ie, that on the valve sleeve by the fuel in the valve chamber no resultant force is exerted in the direction of movement.
  • the control chamber of the nozzle needle is connected via the valve seat with a low pressure / return system and as a result pressure relieved.
  • Such force-balanced control valves are characterized by the fact that because of the high fuel pressures of more than 2000 bar for reasons of strength, a comparatively large valve seat diameter is necessary, otherwise the There is a risk of breakage of the valve piece in the area of the present bore intersections.
  • valve sleeve encloses a separate pressure pin, which only has the task of sealing the valve sleeve located within the valve chamber in the axial direction upwards.
  • the separation of valve piece and pressure pin eliminates the complicated Bohrungsverschneidungen and thus in particular the high tensile stresses loaded areas of the valve piece.
  • the valve seat diameter can be designed much smaller than that of the EP 1 612 403 A1 known prior art is the case.
  • valve sleeve To simplify the guidance of the valve sleeve, was also in the DE patent application 10 2007 022 586.7 proposed to guide the valve sleeve at its outer periphery in a guide sleeve which is formed as a separate component from the valve member and fixed to the valve member by means of a self-locking frictional engagement.
  • valve seat can only be processed by a complex grinding technique. Even with a necessary coating of the surface of the valve seat for the coating process is very difficult to access.
  • valve seat located at the bottom of the guide bore can only be designed as a flat seat or as a concave conical seat, but not as a convex conical seat, the latter seat design being advantageous for reasons of robustness.
  • Object of the present invention is to provide a guide for the valve sleeve with the same accuracy, as is the case with the previous technical solution.
  • the geometry of the guide should allow the valve seat to be freely accessible for machining and coating the surface.
  • a hold-down spring acts, such that the guide sleeve rests self-centering on the axis of the conical outer surface on the valve piece. Due to the spring force of the hold-down spring, the guide sleeve rests with a biasing force on the valve piece. As a result, the guide sleeve is aligned coaxially with the axis of the conical outer surface of the valve piece.
  • the alignment of the guide sleeve on the conical outer surface aligns the guide sleeve and thus also the valve sleeve centered on the valve seat on the valve piece. It thus eliminates a complex, coordinated machining of guide surface and valve seat surface to ensure that match the axis of symmetry of the guide for the valve sleeve and the axis of symmetry of the valve seat.
  • the valve seat surface for processing and / or coating to the outside protruding and thus freely accessible.
  • a secure self-centering of the guide sleeve is achieved when the guide sleeve rests with a circumferential edge on the conical outer surface of the valve piece.
  • the guide sleeve has a conical inner surface, wherein the circumferential edge is formed by an existing between the conical inner surface and a guide bore intersection.
  • a circumferential, circular bearing of the guide sleeve on the valve piece is achieved when the conical outer surface of the valve piece a cone angle ⁇ and the conical inner surface of the guide sleeve have a cone angle ⁇ , and if the cone angle ⁇ of the conical inner surface is greater than the cone angle ⁇ of the conical outer surface ,
  • the hold-down spring can either be supported on a housing-fixed component or advantageously on the valve sleeve or on the magnet armature. In the latter case, the Difference between valve spring force and hold-down spring force acts as a mechanical closing force on the valve seat of the valve sleeve.
  • the hydraulic connection can be achieved by at least one transverse bore in the guide sleeve and / or by at least one legislativenanschliff on the valve sleeve and / or by at least one outflow hole in the valve piece, which then the Abêtbericht, z. B. also down from the low pressure chamber, can dissipate, executed.
  • FIG. 1 shows a schematic representation of a control valve side section of a fuel injector in conjunction with a common rail system.
  • the illustrated control valve-side section of a fuel injector 1 is connected to a common rail system of an internal combustion engine.
  • the common rail system comprises a return line 2, a reservoir 3, a high-pressure pump 4, a fuel reservoir 5 (common rail) and a fuel supply line 6.
  • the control valve-side section of the fuel injector 1 shows a valve body 11, a nozzle needle piston 12 of a nozzle needle, not shown, a control valve 13, an electromagnetic actuator 14 and a housing 15 for the actuator 14.
  • the electromagnetic actuator 14 includes a magnetic coil 43, in a receptacle 44th of the housing 15 is fixed.
  • the valve body 11 is hydraulically tightly inserted in an injector housing, not shown, and separates a low-pressure chamber 17 from a high-pressure chamber 18.
  • the high-pressure chamber 18 is connected to the high-pressure chamber 18, which supplies the high-pressure chamber 18 with system pressure of the high-pressure accumulator 5 by means of the high-pressure pump 4.
  • the low pressure space 17 is on connected to the return line 2, which is acted upon by leak oil pressure and belongs to a Nider horr- / return system.
  • the nozzle needle piston 12 is guided in the valve body 11 and exposed to a pressure surface 21 a control chamber 20. From the high-pressure chamber 18, an inlet bore 23 with an inlet throttle leads into the control chamber 20.
  • the control valve 13 comprises a valve piece 25, a valve sleeve 30 and a guide sleeve 50.
  • the valve piece 25 is integrally connected to the valve body 11.
  • the valve piece 25 is formed with a first conical portion 26, a second conical portion 27 and a coaxial cylindrical recess 37.
  • the first conical section 26 forms a conical outer surface 28 at an angle ⁇ .
  • the second conical section 27 forms a conical valve seat surface 29.
  • the valve sleeve 30 has a plate-shaped magnet armature 31, a receiving bore 32, an end-side annular surface 33 and an outer circumferential surface 34.
  • a push rod 35 is accommodated, which is supported on the housing 15 of the actuating element 14.
  • the push rod 35 has a valve seat-side end face 36.
  • the front-side annular surface 33 is conical, so that it cooperates with a sealing edge with the conical valve seat surface 29 of the valve member 25 and forms a valve seat 38 with this.
  • a valve chamber 40 which is hydraulically connected via a bore 41 with an outlet throttle 42 with the control chamber 20.
  • valve sleeve 30 Due to the fact that the valve sleeve 30 has no axially acting pressure application surface for the fuel within the valve chamber 40, the control valve 13 is a pressure-balanced in the axial direction servo-valve.
  • the guide sleeve 50 has a guide bore 51 in which the outer peripheral surface 34 of the valve sleeve 30 is guided.
  • the guide sleeve 50 is on a valve piece 25 facing end face with a conical Inner surface 52 executed with a cone angle ⁇ .
  • the cone angle ⁇ of the conical inner surface 52 is slightly larger than the cone angle ⁇ of the conical outer surface 28 of the conical portion 26 of the valve piece 25.
  • the intersection between the conical inner surface 52 and the guide bore 51 forms a circular edge 54, with which the guide sleeve 50 rests on the conical outer surface 28 of the valve piece 25.
  • the guide sleeve 50 is aligned coaxially and parallel to the axis of the conical section 26 on the valve piece 25. Since the conical portion 26 and the valve seat 38 forming conical valve seat surface 29 have the same axis of symmetry, the valve sleeve 30 is aligned with the front side annular surface 33 coaxially with the conical valve seat surface 29 of the valve member 25 by the leadership of the valve sleeve 30 in the guide sleeve 50. As a result, the valve seat 38 is present between the valve sleeve 30 and the valve piece 25 as a closed, circumferential line support.
  • annular space 55 is further arranged, which is connected via a guided through the guide sleeve bore 50 56 with the low-pressure chamber 17.
  • the executed as a hydraulic connection bore 56 may also be carried out by means of aassinanschliffs to the valve sleeve 30 or at least one outflow bore in the valve member 25, which then discharges the Abêt fie in the low-pressure chamber 17.
  • one or more radially extending grooves may be provided in the conical inner surface 52.
  • the valve sleeve 30 is biased by a first closing spring 46 in the closing direction of the valve seat 38 against the conical annular surface 29.
  • the guide sleeve 50 is pressed against the valve piece 25 by means of a second hold-down spring 47, which is supported for example on the valve sleeve 30.
  • a closing force for the valve sleeve 30 and valve seat 38 it is necessary that the force of the closing spring 46 is greater than the pressing force of the hold-down spring 47, because the mechanical closing force for the valve seat 38 results from the difference in the spring forces of the closing spring 46 and hold-down spring 47.
  • the actuator 14 is actuated by the armature 31 is pulled to the solenoid 43.
  • the valve sleeve 30 moves in the axial direction upwards and the valve seat 38 is released.
  • This creates a hydraulic connection between the valve chamber 40 and the low-pressure chamber 17 via the annular space 55 and the bore 56.
  • the control chamber 20 is consequently connected to the low-pressure chamber 17 and thereby pressure-relieved.
  • On an unillustrated pressure shoulder of the nozzle needle acts an outgoing from the high-pressure chamber 18 opening force, which is greater than the force acting in the control chamber 20 on the pressure surface 21 closing force.
  • the nozzle needle lifts off the nozzle needle seat and fuel is injected at the system pressure of the high-pressure fuel accumulator 6 into the combustion chamber of the internal combustion engine.
