Definitions
- the invention is based on a method for mounting a filter on the circumference of a valve body delimiting a valve in the radial direction to the outside according to the preamble of patent claim 1 41 010, which is regarded as the closest prior art, a filter element is pushed onto the valve housing, so that the at least one continuous opening formed on the circumference of the valve housing is covered by the filter fabric in the area of the throughflow openings of the filter element.
- the filter element is produced by extrusion-coating a filter fabric with plastic in an injection mold.
- diameter gradations with rounded edges are required on the valve body in order to enable the filter element to be pushed onto the valve body, for example onto the valve housing of the valve.
- the formation of these diameter gradations increases the manufacturing costs of a valve manufactured in this way.
- the inventive method for mounting a filter on the circumference of a valve in the radial direction outwardly delimiting valve body with the features of claim 1 has the advantage that the contamination of the valve interior is avoided because no filter is pushed onto the valve body, so that no material particles can scrape off.
- the tightness between the plastic overmold serving as a tissue holder and the valve body is achieved by shrinking the plastic overmold onto the valve body immediately after the spraying process due to the cooling of the plastic material.
- a further advantage is that the valve can be manufactured more easily and cost-effectively, since no diameter gradations with rounded edges on the circumference of the valve body are required for mounting the filter.
- valve body has at least one recess on its circumference, which is filled by the plastic encapsulation. This ensures a secure and reliable hold of the filter on the circumference of the valve body.
- valve body has at least one flattened portion on its circumference, which is closely surrounded by the plastic encapsulation of the filter. This effectively prevents the filter from rotating around the circumference of the valve body.
- FIG. 1 shows a first exemplary embodiment of a valve with a filter mounted according to the invention
- FIG. 2 shows a partial section of the first exemplary embodiment shown in FIG. 1
- FIG. 3 shows a second
- FIG. 4 shows a third exemplary embodiment of a valve with a filter mounted according to the invention.
- valves shown in FIGS. 1 to 4 in the form of electromagnetically actuated fuel injection valves for fuel injection systems of, for example, mixture-compression-ignition internal combustion engines have a filter 1 mounted according to the invention, which is used to filter a fluid supplied to the valve.
- the same and equivalent parts are identified in the four figures by the same reference numerals.
- the filter 1 is arranged on the circumference of a tubular nozzle body 5 delimiting the valve in the radial direction towards the outside.
- the nozzle body 5 has at least one, for example two through openings 7 in the form of partially circumferential slots on its circumference, all of which are at least approximately at the same axial height of the nozzle body 5.
- These through openings 7 are used for supply e.g. a fuel into the interior of the tubular nozzle body 5.
- this has at one end an electrical connector 11 which serves to contact a magnetic coil, not shown.
- a seat body 13 is inserted into a longitudinal opening 14 of the nozzle body 5, which is concentric with a longitudinal valve axis 9.
- the seat body 13 is connected on its circumference to the wall of the longitudinal opening 14 at its end facing away from the electrical connector 11, for example by a laser weld 16.
- the seat body 13 has, in the upstream direction toward the through openings 7 of the nozzle body 5, a guide bore 15 which runs concentrically to the longitudinal valve axis 9 and in which a ball 17 serving as a valve closing body is slidably mounted.
- a fixed valve seat 19 is formed in the seat body 13 downstream of the guide bore 15 and cooperates with the ball 17.
- the wall of the guide bore 15 is interrupted by fuel channels 21 running in the axial direction, which enable fuel flow to the valve seat 19.
- Downstream of the valve seat 19, for example, two spray openings 23 are formed in the seat body 13, which spray the fuel into a treatment bore 25 of the seat body 13 which extends concentrically to the longitudinal valve axis 9 and widens in the downstream direction.
- the ball 17 serving as a valve closing body is connected to the valve seat 19, directly connected to a tubular armature 27, for example by laser welding.
- the armature 27 interacts with the magnet coil and a core (not shown) of the valve and serves to actuate the valve.
- a holding shoulder 31 is formed, on which a return spring 33 is supported, facing the valve seat 19 of the seat body 13.
- the return spring 33 strives to act as a valve closing body serving ball 17 to move in the direction of its valve seat 19 and thus close the valve.
- a filter fabric 35 is arranged on the circumference of the nozzle body 5 in a first method step according to the invention in such a way that the two through openings 7 of the nozzle body 5 are covered by the filter fabric 35, for example.
- an annular filter fabric 35 In order to enable simple assembly of the filter fabric 35 on the circumference of the nozzle body 5 and to ensure that the filter fabric 35 is held on the nozzle body 5 until the filter 1 is finished, it is expedient to use an annular filter fabric 35.
- Such a filter cloth 35 can be e.g. by welding the two ends of a band-shaped filter fabric.
- FIG. 3 shows a second exemplary embodiment of a valve with a filter mounted according to the invention
- the filter fabric pieces thus only partially extend over the circumference of the nozzle body 5.
- At least one recess 37 is formed on the circumference of the nozzle body 5, for example in the area covered by the filter fabric 35, which in the first exemplary embodiment shown has the shape of a circumferential groove.
- the nozzle body 5 is provided in the area of the filter fabric 35 with a plastic overmold 39 which partially covers the filter fabric 35 and which cools and shrinks after the spraying process, so that the filter fabric 35 is fixed in its position in relation to the through openings 7 of the nozzle body 5 and the plastic extrusion 39 sealingly encloses the nozzle body 5.
- the most The circumference of the nozzle body 5 formed recess 37 is filled by the plastic extrusion 39 and thus a particularly firm and secure hold of the filter 1 consisting of filter fabric 35 and plastic extrusion 39 is achieved in the axial direction on the circumference of the nozzle body 5.
- at least one flattening 38 is formed on the circumference of the nozzle body 5 in the region of the plastic encapsulation 39, which is caused by the plastic encapsulation 39 is closely surrounded.
- the plastic encapsulation 39 of the filter 1 has an upper collar 40 at its end facing away from the valve seat 19 and a lower collar 42 at its end facing the valve seat 19.
- flow openings 48 are formed in the plastic encapsulation 39, which cover the filter fabric 35 in the area of the through openings 7 of the nozzle body 5 and thus serve to supply the valve with fuel.
- the throughflow openings 48 are delimited by axially extending webs 50, which connect the upper collar 40 and the lower collar 42 of the plastic encapsulation 39 of the filter 1 to each other, support the filter fabric 35 of the filter 1 and securely and reliably surround it in the area of the throughflow openings 48 hold the nozzle body 5.
- the nozzle body 5 In the area of the laser weld seam 16 running in a circumferential reduction in cross section 52 of the nozzle body 5, the nozzle body 5 is surrounded by a retaining collar 54.
- the circumferential retaining collar 54 becomes partial when a valve is formed in the axial direction surrounding plastic sheath 56 applied.
- the plastic material of the retaining collar 54 fills the circumferential reduction in cross section 52 of the nozzle body 5 and thus protects the laser weld 16 in a simple manner against external damage.
- a sealing ring 58 is arranged on the circumference of the nozzle body 5 in the axial direction between the lower collar 42 of the filter 1 and the retaining collar 54.
- the sealing ring 58 serves to seal between the circumference of the valve and a valve receptacle, not shown, for example an intake line of the internal combustion engine.
- FIG. 4 shows a third exemplary embodiment of a valve designed, for example, as a fuel injection valve with a filter 1 mounted according to the invention.
- the filter 1 is arranged on the circumference of a valve housing 61 which delimits the valve in the radial direction towards the outside.
- the valve housing 61 has, for example, six through openings 7 in the form of bores on its circumference, all of which are at least approximately at the same axial height and which are used for supplying e.g. a fuel through the wall of the valve housing 61 into the interior of the valve or the outflow of excess fuel from the valve.
- the filter fabric 35 for example in the form of a ring, is arranged on the circumference of the valve housing 61 in a first method step according to the invention in such a way that the six through openings 7 are covered by the filter fabric 35.
- the valve housing 61 is provided in the region of the filter fabric 35 with a plastic coating 39 which partially covers the filter fabric 35 and cools and shrinks after the injection process, so that the filter fabric 35 is held in its position in relation to the through openings 7 of the valve housing 61 and the plastic extrusion 39 sealingly encloses the valve housing 61.
- the upper collar 40 and the lower collar 42 of the plastic encapsulation 39 of the filter 1 essentially serve to hold the filter 1 on the circumference of the valve housing 61.
- Flow openings 48 are formed which cover the filter fabric 35 in the area of the passage openings 7 of the valve body 5.
- the webs 50 formed in the axial direction between the upper collar 40 and the lower collar 42 limit the throughflow openings 48 in the circumferential direction of the filter 1, support the filter fabric 35 of the filter 1 and hold it on the circumference of the valve housing 61.
- a sealing ring 63 is arranged on the circumference of the valve housing 61.
- the axial mobility of the sealing ring 63 is limited by the upper end face 44 of the upper collar 40 of the filter 1 and a holding flange 65 of the plastic jacket 56 of the valve, which faces the electrical connector 11 of the valve.
- the method according to the invention has the advantage that a filter 1 is formed in a simple manner by directly applying the plastic encapsulation 39 to the circumference of the valve body 5, 61 in the area of the filter fabric 35, so that contamination of the valve interior is avoided.
