Definitions

  • the invention relates to a lever device for an injection valve, comprising a housing, at least one lever element, a drive element and an output element.
  • the invention further relates to an injection valve for an internal combustion engine of a motor vehicle, which comprises the lever device and a valve needle which is coupled to the output element or which forms the output element.
  • Injection valves for an internal combustion engine of a motor vehicle may have actuators which are designed in particular as piezoactuators. Such actuators have a piezoceramic material. Such actuators may change their longitudinal extent depending on an electric field acting in the piezoceramic material. Piezoelectric actuators, which are used as actuators, in particular in injection valves for internal combustion engines in motor vehicles, are arranged in a housing so that they can perform a lifting movement in the axial direction. The actuator may in particular be coupled to a lever device by means of which the stroke of the actuator can be translated.
  • the international publication WO 2007/116007 A1 discloses an injection valve having a lever member in a housing recess of the injection valve, which is able to convert the downward movement of an actuator of the injection valve in an upward movement of a nozzle needle of the injection valve.
  • the object of the invention is to provide a lever device for an injection valve, which is permanently reliable.
  • the object is also to provide an injection valve, which has a long life.
  • the invention is characterized by a lever device for an injection valve, comprising a housing having a housing recess, at least one lever element which is arranged in the housing recess and has a coupling portion which is coupled to a portion of the housing Drive element which is arranged in the housing recess and is coupled to the at least one lever element for acting on the at least one lever element in the direction of a force action axis, and arranged in the housing recess output element which is coupled to the at least one lever element such that the output element of the at least one lever element is movable in the direction of the force action axis.
  • the coupling portion of the lever member has at least one recess, by means of which at least two contact surfaces of the coupling portion are formed, which are spaced apart and bear against the portion of the housing.
  • lever element in a region between the contact surfaces of the coupling portion can achieve a low rigidity. It can thus be achieved that mechanical irregularities on the at least one lever element and / or on the portion of the housing only slightly influence the movement of the lever element and thus changes in the injection quantities can be low or avoided. As a result, a long-term reliable operation of the lever device and thus of the injection valve can be made possible.
  • the at least two contact surfaces of the coupling portion are formed as convex curved surfaces. This has the advantage that the friction and the wear of the lever element can be very small. For example, a rolling rolling of the lever element keep the load on the contact surfaces low relative to the section of the housing. This can be made possible by the at least one lever element permanently reliable operation of the lever device.
  • the invention is characterized by an injection valve, which comprises the lever device and a valve needle.
  • the valve needle is coupled to the output element or forms the output element.
  • the drive element and the valve needle are coupled to one another via the lever device in such a way that the valve needle in a closed position prevents fluid flow through the injection valve and otherwise releases it. Due to the distance between the at least two contact surfaces of the coupling portion such a valve can be operated permanently reliable.
  • FIG. 1 shows a valve, in particular an injection valve 10 for an internal combustion engine in a motor vehicle.
  • the injection valve 10 has a housing 12.
  • the housing 12 has a plurality of sections 12a, 12b.
  • the housing 12 has, in particular, a disc-shaped section 12 a, which is arranged between two tubular sections 12 b of the housing 12.
  • the disc-shaped portion 12 a and the two tubular portions 12 b are fixedly coupled together and together form the housing 12.
  • a housing recess 14 with a fluid inlet 16 and a fluid outlet 18 is formed in the housing 12.
  • fuel can be supplied to the injection valve 10 in the region of the fluid inlet 16.
  • a valve needle 20 is arranged axially movable, which closes an injection nozzle 22 in a closed position and otherwise allows fuel flow through the injection nozzle 22.
  • the injection valve 10 includes a piezoelectric actuator 24.
  • the piezoelectric actuator 24 may also be be provided other actuator, such as a magnetostrictive actuator or an electromagnetic actuator.
  • the injector 10 further includes a drive element 26 coupled to the actuator 24.
  • the drive element 26 preferably includes a pin or rod that transmits the stroke and a drive force of the actuator 24.
  • the actuator 24 and the drive element 26 are coupled together in the axial direction.
  • a stroke of the drive element 26 is dependent on an axial extent of the piezoelectric actuator 24, which is dependent on a control signal which can be supplied to the piezoelectric actuator 24.
  • the drive element 26 further comprises a preferably bell-shaped component 27.
  • a lever device 28 is further arranged.
  • the lever device 28 comprises the drive element 26 and a lever element 30 or a plurality of lever elements 30.
  • the lever device 28 has two lever elements 30 (see also FIGS FIG. 2 ).
  • the lever elements 30 are coupled to the drive element 26.
  • the lever elements 30 are coupled to an output element 32.
  • the output element 32 is arranged in the housing recess 14.
  • the output element 32 is preferably coupled to the valve needle 20.
  • the valve needle 20 may also form the output element 32.
  • the drive member 26, the lever member 30 and the output member 32 cooperate such that the stroke of the drive member 26 is transmitted to the valve needle 20 and that the valve needle 20 is thus moved to its closed position or to an open position.
  • a force action axis A of a drive force of the drive member 26 passes through the drive member 26 and as a force action axis of a driven force further through the Output element 32.
  • the force action axis is offset by the drive element 26 to the force action axis by the output member 32nd
  • FIG. 2 shows an embodiment of the lever device 28 in a cross section.
  • the lever elements 30 each have a coupling region 134.
  • the output element 32 has two plane wall sections 136.
  • the planar wall sections 136 face one another with respect to the force action axis A of the output element 32.
  • the coupling regions 134 of the lever elements 30 each have a planar wall section 138.
  • the planar wall sections 138 of the lever elements 30 are assigned to the planar wall sections 136 of the output element 32. In each case one of the planar wall sections 138 of the lever element 30 is opposite to a planar wall section 136 of the output element 32.
  • planar wall portions 136 of the output member 32 cooperate with the planar wall portions 138 of the lever member 30, and thus allow the lever members 30 are rotatably coupled to the output member 32 with respect to the force axis A of action. It can thus be achieved that the lever elements 30 can no longer rotate with respect to the valve needle 20. Thus, the conditions in the injection of the injection valve 10 can be kept constant over many injection events.
  • the coupling portions 134 of the lever members 30 have planar wall portions 138.
  • the housing recess 14 of the housing 12 has two planar wall portions 140, which face each other with respect to the force axis A of action.
  • one of the planar wall sections 138 of one of the lever elements 30 acts with one of plan wall portions 140 of the housing recess 14 together. It can thereby be achieved that the lever element 30 is coupled to the housing 12 in a rotationally fixed manner with respect to the force action axis A.
  • the rotationally fixed coupling of the lever members 30 to the housing 12 it is possible that the contact conditions between the lever members 30 and the housing 12 can be kept constant over a long period of time.
  • the injection behavior of the injection valve 10 can be kept constant over a long period of time.
  • FIGS. 3 to 6 show an embodiment of the lever member 30 in different views.
  • the lever member 30 has a coupling portion 34.
  • the coupling portion 34 is coupled to the disk-shaped portion 12a of the housing 12 (see also Figs FIG. 1 ).
  • the coupling portion 34 has a recess 36.
  • the recess 36 is formed such that on the coupling portion 34, two contact surfaces 38 are formed, which are spaced apart.
  • the two contact surfaces 38 of the coupling portion 34 abut against a contact surface 40 of the disk-shaped portion 12 a of the housing 12.
  • the contact surface 40 of the disk-shaped portion 12a of the housing 12 has a surface normal which is parallel to the force action axis A.
  • the two contact surfaces 38 of the coupling portion 34 are formed as convex curved surfaces. It can thus be achieved that the lever element 30 can roll over the disk-shaped section 12a of the housing 12 in a rolling manner.
  • the disc-shaped portion 12a of the housing 12 has a raised portion 44 which lies between the contact surfaces 38 of the coupling portion 34 in the region of the recess 36 of the coupling portion 34. Due to the design of the recess 36 of the coupling portion 34, the lever member 30 may be supported without interference by the survey 44 relative to the disc-shaped portion 12 a of the housing 12. A movement of the lever member 30 relative to the disk-shaped portion 12a of the housing 12 via the contact surfaces 38 of the coupling portion 34 and the contact surface 40 can be done so undisturbed by the survey 44.
  • the disk-shaped portion 12 a of the housing 12 has a further elevation 44 a, which lies in the region of one of the contact surfaces 38 of the coupling portion 34. Due to the formation of the recess 36 of the coupling portion 34, the lever member 30 in the region of the recess 36 has a low rigidity. It can thereby be achieved that upon movement of the lever element 30 relative to the disk-shaped section 12a of the housing 12, the lever element 30 can yield in the region of the recess 36. It can thereby be achieved that the further elevation 44a has only a slight influence on the movement of the lever element 30 and thus the movement of the output element 32.
  • the lever element 30 has further coupling sections 42a, 42b ( FIG. 9 ).
  • One of the further coupling sections 42a is coupled to the output element 32.
  • Another of the further coupling sections 42b is coupled to the bell-shaped component 27 of the drive element 26 (see FIG FIG. 1 ).
  • the further coupling section 42a which is coupled to the output element 32, is arranged opposite the further coupling section 42b, which is coupled to the drive element 26, such that the greatest possible distance to the lever element 30 is achieved between the further coupling sections 42a, 42b becomes.
  • the lever element 30 may have a lower rigidity in the area between the further coupling sections 42a, 42b than in the region of the further coupling sections 42a, 42b. It can thus be achieved that upon movement of the lever element 30 relative to the drive element 26 or the output element 32, the lever element 30 can yield in the region between the further coupling sections 42a, 42b. It can thus be achieved that mechanical irregularities on the drive element 26 or the output element 32 have only a small influence on the movement of the lever element 30 and, as a consequence, on the movement of the output element 32.
  • lever elements 30 with the recess 36 of the coupling portion 34 can be achieved that the lever elements 30 can interact via a plurality of injection operations with the disc-shaped portion 12 a of the housing 12 without the transfer behavior between the lever members 30 and the disk-shaped Section 12a of the housing 12 changed significantly.
  • 10 stable injection conditions of the injection valve 10 can be achieved via a variety of injection processes of the injection valve 10. It can thereby be achieved that component tolerances, in particular of the lever element 30 and / or the disk-shaped portion 12a of the housing 12, such as by the elevations 44, 44a only to a small extent or not at all affect the injection quantities of the injection valve 10.
