Definitions
- the invention relates to a valve for metering a fluid, in particular a
- a valve for metering fluid is known.
- the known valve has an electromagnet for actuating a valve needle controlling an orifice.
- the electromagnet is used to operate one on one
- Valve needle movable anchor has a valve needle adjacent to the bore, which forms a spring receptacle for a Vorhubfeder.
- This embodiment has the disadvantage that a guide between the anchor and the
- valve according to the invention with the features of claim 1 has the advantage that an improved design and operation are possible.
- an improved guide between the armature and the valve needle and the valve needle along a longitudinal axis of the housing can be realized.
- valve for metering the fluid serving as armature armature is not fixedly connected to the valve needle, but mounted between stops flying.
- a stop may be formed on a stop element, which can be realized as a stop sleeve and / or stop ring.
- the stop element can also be formed integrally with the valve needle.
- the anchor is in
- Hibernation adjusted to a relative to the valve needle stationary stop, so that the armature rests there.
- the complete armature free travel is then available as an acceleration section, whereby the spring is shortened during acceleration.
- the Ankerokweg can be specified via the axial clearance between the anchor and the two stops.
- Pen holder is. This makes it possible, for example, that the spring seat directly adjacent to the valve needle.
- Advantageous embodiments of this guide extension and the anchor are specified in claim 4. As a result, in particular a robust design is possible in which the guide extension can absorb impact forces.
- the development according to claim 5 has the advantage that the guide extension can be formed in particular with an outer diameter within
- Mouth openings of through openings of the armature is located, which serve for passing a fluid through the armature. This has a favorable effect on the operating behavior.
- the development according to claim 6 has the advantage that a guide can be realized, which is just as good or even better than an anchor without spring retainer.
- the development according to claim 7 has the advantage that the spring can dip completely into the spring receptacle during actuation, so that an optimal compromise can be achieved with respect to several disadvantages of a conventional design.
- the disadvantages of a conventional embodiment relate to the first manufacturability, cost and installation, if an embodiment is realized without spring receiving, in which an additional component for receiving the spring and its connection to the Anchor is required.
- a third disadvantage relates to a magnetic short circuit across the spring and the consequent loss of magnetic force, resulting in a slower force build-up and a lower holding force in the open state. This usually applies to the magnetic spring steels used, which constitute a bypass for the magnetic flux between the armature and the inner pole.
- a fourth disadvantage relates to the smaller contact surface between the armature and a stop ring in a variant in which the stop ring is immersed in the spring receptacle formed on the armature. This can cause increased wear and reduced hydraulic damping.
- a lever arm between the upper needle guide and the anchor may arise, which in particular relates to the above-mentioned embodiment, in which the stop ring is immersed in the spring receptacle.
- a sixth possible disadvantage concerns embodiments in which a large spring diameter is needed. Due to the limited radial space then lower spring forces can be realized, which is bad for a fast anchor calming after the first injection, especially with respect to multiple injections. For the same spring force means a larger spring diameter also has a greater tilting moment on the armature, which is also disadvantageous for the injector function and in particular may have a tilted anchor stop result.
- Disadvantage relates to the risk of buckling of the spring under load and the consequent contact of the inner pole and / or the stop ring due to a relatively long
- Undefined friction which in addition to a possible wear and the formation of particles has significant variations in the injection behavior.
- the stop element can be made of a non-magnetic material, whereby it can separate the inner pole from a magnetic point of view of the anchor.
- the lever arm can be kept short.
- Both a pole face and a stop surface between the armature and the stop element, in particular stop ring, can be chosen to be sufficiently large.
- a relatively small Inner diameter of the spring can be realized so that relatively high spring forces can be achieved even with a comparatively thin wire thickness of the spring.
- the spring can also be designed to be relatively short, so that the risk of bulging and a corresponding wear occurring is reduced and an in this regard initiated on the anchor tilting moment remains within reasonable limits.
- Housing can be achieved. Furthermore, in a further possible embodiment, an annular gap between the armature and the housing can be minimized. In terms of predetermined housing dimensions, this results in a fast power and a large holding power.
- Spring receptacle can also be designed to be larger the inner pole facing end side of the armature than when separate through holes are realized.
- Flow cross-section can be increased disproportionately to the consequent reduction in the area of the front side of the armature.
- the development according to claim 10 has the advantage that an advantageous fuel flow in the region of the stop element can be achieved without the inner bore of the inner pole has to be increased.
- FIG. 1 shows a valve in an excerpt, schematic sectional view according to a first embodiment.
- FIG. 2 shows a valve in an excerpt, schematic sectional view according to a second embodiment.
- Fig. 1 shows a valve 1 for metering a fluid in an extract
- the valve 1 has a housing (valve housing) 2, in which a stationary inner pole 3 is arranged. Through the housing 2, a longitudinal axis 4 is determined here as
- Reverence for guiding a arranged within the housing 2 valve needle 5 is used. This means that during operation, an alignment of the valve needle 5 along the longitudinal axis 4 should take place.
- an armature (armature) 6 is arranged at the valve needle 5.
- a stop element 7 and a further stop element 8 are also arranged.
- stops 7 ', 8' are formed at the stop elements 7, 8 stops 7 ', 8'.
- the armature 6 can in this case be moved during an actuation between the stop elements 7, 8, wherein a
- Ankerokweg 9 is specified.
- the armature 6, the inner pole 3 and a solenoid, not shown, are components of an electromagnetic actuator 10th
- valve closing body 11 On the valve needle 5, a valve closing body 11 is formed, which cooperates with a valve seat surface 12 to a sealing seat. Upon actuation of the armature 6, this is in
- the valve 1 has a return spring 14, which the valve needle 5 via the
- Stop element 7 adjusted to its initial position in which the sealing seat is closed.
- the armature 6 is based on a cylindrical basic shape 20 with a through hole 21, wherein the armature 6 is guided on the through hole 21 on the valve needle 5.
- the basic shape 20 of the armature 6 has a length L between an end face 22 facing the inner pole 3 and an end face 23 facing away from the inner pole 3.
- the armature 6 has a spring receptacle 25.
- the spring receptacle 25 is in this case opened at the end face 22 of the armature 6.
- the spring receptacle 25 has along the longitudinal axis 4 a length f between the end face 22 and a spring support surface 26 of the armature 6.
- the spring support surface 26 in this case represents the bottom 26 of the spring seat 25.
- Spring seat 25 arranged spring 27 on a spring length F.
- the spring length F is thus the spring length F of the spring 27 in the unactuated initial state.
- the spring 27 is supported on the one hand on the spring support surface 26 of the armature 6 and on the other hand on the stop 7 'of the stopper 7 from.
- the spring length F is greater than the length f of
- a guide web 28 is formed in this embodiment.
- the armature 6 has a (shortened) length I along the longitudinal axis 4. Without the guide bar 28, only this shortened length I would be available as a guide length.
- the length I is extended by the length s of the guide web 28 along the longitudinal axis 4.
- the length s of the guide web 28 is preferably the same size or even greater than that
- Length f of the spring seat 25 is selected.
- the guide length I + s of the armature 6 on the valve needle 5 is equal to or even greater than the length L of the armature 6 between its end faces 22, 23.
- Housing 2 results in this embodiment via the stop element. 7
- the stop element 7 is guided in a guide region 30 on an inner bore 31 of the inner pole 3. Possible embodiments of the stop element 7, which allow an advantageous passage of the fluid, in particular fuel, are described with reference to FIGS. 5 to 8.
- an annular gap 34 results between an outer side 32 of the armature 6 and an inner side 33 of the housing 2.
- the guidance of the valve needle 5 can additionally or alternatively also be realized via the armature 6.
- the outer side 32 of the armature 6 extends at least partially up to the inner side 33 of the housing 2. In this case
- valve needle 5 along the longitudinal axis 4 can be realized.
- Fig. 2 shows a valve 1 in an excerptive, schematic sectional view according to a second embodiment.
- a guide extension 40 is provided.
- the guide extension 40 has a length s' along the longitudinal axis 4, around which the guide of the armature 6 on the valve needle 5 extends. This means that in this embodiment, the guide length s' + I along the longitudinal axis 4 between the armature 6 and the valve needle 5 is realized.
- the spring seat 25 directly adjacent to the valve needle 5.
- This facilitates, in particular, the production of the armature 6, since the spring receiver 25 can be realized by a cylindrical recess aligned with the longitudinal axis 4.
- shortened length I is available directly to the basic shape 20 of the armature 6. This shortened length I is thereby extended to a certain extent via the guide extension 40 by the length s'.
- the length s ' may be predetermined so that the guide length s' + I is equal to or even greater than the length L of the armature 6 between its end faces 22, 23.
- the guide extension 40 is designed sleeve-shaped. This means that an outer diameter 41 on the guide extension 40 is chosen to be significantly smaller than an outer diameter 42 on the outer side 32 of the armature 6.
- the spring 27 in this embodiment with beveled spring ends 43, 44 configured. This results in an even better edition. Furthermore, reduced wear and a more uniform introduction of force on the one hand into the armature 6 on the spring support surface 26 and on the other hand on the stop T of the stop element 7.
- 3 and 4 show possible embodiments of the armature 6 of the valve 1 from the viewing direction indicated in Fig. 1 with III, wherein for better understanding, the valve needle 5 is shown as a sectional area.
- the end face 22 is divided into partial surfaces 22A and 22B, between which the spring receiver 25 is provided. Further, passage openings 51 to 54 are provided, which are configured in this embodiment as through holes 51 to 54 of circular cross-section. This results in intersections between the through holes 51 to 54 and the spring seat 25.
- Total area of the end face 22, which is composed of the partial surfaces 22A, 22B, is further reduced. This has a favorable effect on the control behavior during actuation of the armature 6, since both a large magnetic force and a reduced hydraulic throttling result.
- Fig. 5 to 8 show possible embodiments of the stop element 7 of the valve 1 against the direction of view designated in Fig. 1 with III, wherein the valve needle 5 is shown in section for the purpose of illustration.
- a support portion 60 is predetermined for the spring 27.
- the support portion 60 is bounded radially outwardly by an interrupted line 60A.
- the support portion 60 is bounded radially inwardly by an interrupted line 60I.
- the support portion 60 serves as the structurally given support portion 60 in which the selected spring 27 is to be supported.
- the embodiments preferably relate to an application in which a guide between the stop element 7 and the inner pole 3 is realized, as illustrated for example in FIG. 1.
- depressions 61 to 64 are provided.
- hollow cylindrical basic shape 65 characterized by an outer diameter D. is to be modified by such recesses 61 to 64. This results in both the possibility of a guide on the outer diameter D and a
- the recesses 61 to 64 are here designed so that they are considered from the longitudinal axis 4 from a maximum of up to a diameter d. This means that from the valve needle 5 to the diameter d an annular surface 66 remains.
- the diameter d is set to be between the outer line 60A and the inner line 601.
- the spring 27 also lies at least partially in the region of the depressions 61 to 64, namely at least on the annular surface 66, against the support region 60. This results in a compromise between a good contact of the spring 27 on the support portion 60 and the largest possible recesses 61 to 64 and at the same time the possibility of a guide on the outer diameter D.
- FIGS. 5 to 8 show various possibilities, the depressions 61 to 64
- Fig. 5 as an intersection with cylinder bores
- Fig. 6 as intersections with rectangular cutouts
- Fig. 7 as an intersection with flats.
- the flow cross-section can be formed by ring segments.
