Definitions
- the invention relates to a valve for metering a fluid, in particular a fuel injection valve for internal combustion engines.
- the invention relates to the field of injectors for fuel injection systems of motor vehicles, in which fuel is preferably injected directly into the combustion chambers of an internal combustion engine.
- a valve for metering fluid is known.
- the known valve has an electromagnet for actuating a valve needle controlling a metering opening.
- the electromagnet is used to actuate an armature that is displaceable on a valve needle.
- the armature has a bore adjoining the valve needle which forms a spring receptacle for a forward stroke spring.
- the valve according to the invention with the features of claim 1 has the advantage that an improved design and functionality are made possible.
- improved guidance between the armature and the valve needle, in particular damping and calming of the armature, and at the same time an advantageous passage of the fluid through an armature space can take place.
- the armature serving as a magnet armature is not permanently connected to the valve needle, but is mounted overhung between stops.
- a stop can be formed on a stop element that can be implemented as a stop sleeve and / or stop ring.
- the stop element can, however, also be designed in one piece with the valve needle.
- the anchor in the Rest position adjusted to a fixed stop with respect to the valve needle, so that the armature rests there.
- the entire armature free travel is then available as an acceleration path, with the spring being shortened during acceleration.
- the armature free travel can be specified via the axial play between the armature and the two stops.
- a guide length between the armature and the valve needle can be increased in that the spring receptacle is configured by an annular groove that is not adjacent to the valve needle.
- the spring receptacle can advantageously be designed close to the longitudinal axis, i.e. with a small radial distance from the longitudinal axis, in order to enable an advantageous introduction of the fluid from the first area of the armature chamber into the spring receptacle with a corresponding design of the valve.
- the resulting situation has the advantage of a low adhesion effect when the anchor is released from the respective stop element during an actuation process, it also leads to a reduction in the damping desired for damping an impact or for anchor calming. Especially when closing the valve, this can mean that too long a duration is required for the armature to settle sufficiently in relation to the desired activation times. With regard to possibly very short pause times, for example of less than 1.2 ms, as may be desired in the case of a multiple injection, there are thus considerable disadvantages of a straight through-flow bore through the armature designed close to the valve needle.
- a proposed fluid channel can be used to conduct fluid through the armature space and at the same time reduce impairment of damping behavior, which is particularly advantageous for calming the armature when the valve is closed.
- the structural design of the stop surface on the stop element at least A specification or setting of the desired damping can be achieved largely unaffected by the passage of the fluid through the armature.
- a further development in which a point of a first opening of the fluid channel that is radially as far outward as possible from the longitudinal axis is closer to the longitudinal axis than a point of a second opening of the fluid channel which is radially as far outward as possible from the longitudinal axis, has the advantage that on the first end face of the Armature, the fluid can advantageously be introduced into the fluid channel near the longitudinal axis, while the opening of the fluid channel can be relocated to an area further away from the valve needle on the second end face of the armature.
- the further development according to claim 2 has the particular advantage that an overlap of the opening of the fluid channel on the second end face of the armature with a stop surface on the second stop element can be reduced or avoided entirely.
- the point of the second opening of the fluid channel that is located maximally inward can lie radially outside a stop surface of the second stop element.
- the further development according to claim 5 has the advantage that, on the one hand, a fluid channel configuration that is favorable in terms of flow can be realized.
- a configuration of the fluid channel that is favorable in terms of production technology can optionally be implemented, as is possible in particular according to the development according to claim 6.
- an optimization with regard to a tilt angle with which an axis of the inclined bore is tilted relative to the longitudinal axis can be implemented, the tilt angle, for example, given given specifications for the opening on the second face of the armature can be kept optimally small.
- the cross section available for the passage of the fluid along the coaxial direction can be enlarged over the entire course through the armature, if this is useful in the respective application.
- armature free travel spring armature free travel spring
- the development according to claim 9 in particular enables the spring receptacle to be used along its entire extent along the longitudinal axis.
- the fluid channel can be designed in an advantageous manner by means of coaxial blind bores which are easy to implement in terms of manufacturing technology.
- a combination of an armature free travel spring located in the armature with an armature which has a radially outwardly extending fluid channel, in particular an inclined bore, can thus be implemented in an advantageous manner.
- This combination makes it possible that a maximum large damping surface can be realized between a stop element and the armature. In particular, a reduction in the damping area can be avoided by overlapping the corresponding opening.
- several fluid channels are preferably provided in the design of a valve, which are preferably implemented instead of conventional flow bores, this can have a significant influence on the functioning of the valve, in particular significantly improved damping.
- two to ten fluid channels, in particular two to six fluid channels can be implemented.
- Such fluid channels can here together at least partially include the spring receptacle. This can also improve the flow behavior.
- an embodiment with only a single fluid channel or a combination with at least one proposed fluid channel with at least one conventional through-hole is also conceivable.
- an embodiment can thus be implemented in which, with respect to a stop surface on the relevant stop element, there is no longer any overlap between the relevant opening or the relevant openings of the at least one fluid channel and the stop surface on the stop element. This means that the maximum damping area is available.
- Fig. 1 shows a valve 1 for metering a fluid in a partial, schematic sectional illustration according to a first embodiment.
- the valve 1 can in particular be designed as a fuel injector 1.
- a preferred application is a fuel injection system in which such fuel injection valves 1 are designed as high pressure injection valves 1 and are used for direct injection of fuel into assigned combustion chambers of the internal combustion engine. Liquid or gaseous fuels can be used as fuel. Accordingly, the valve 1 is suitable for metering liquid or gaseous fluids.
- the valve 1 has a housing (valve housing) 2 in which an inner pole 3 is arranged in a stationary manner.
- An armature (magnet armature) 6 is arranged on the valve needle 5.
- a stop element 7 and a further stop element 8 are also arranged on the valve needle 5.
- Stop surfaces 7 ', 8' are formed on the stop elements 7, 8.
- the longitudinal axis 4 can be referred to here as the longitudinal axis 4 of the valve needle 5 or as the longitudinal axis 4 of the armature 5.
- the armature 6, the inner pole 3 and a magnetic coil (not shown) are components of an electromagnetic actuator 10.
- a valve closing body 11 is formed on the valve needle 5, which cooperates with a valve seat surface 12 to form a sealing seat.
- the armature 6 When the armature 6 is actuated, it is accelerated in the direction of the inner pole 3.
- the armature 6 strikes the stop 7 'of the stop element 7 and thereby actuates the valve needle 5, fuel can be injected into a space, in particular a combustion chamber, via the open sealing seat and at least one nozzle opening 13.
- the valve 1 has a return spring 14 which moves the valve needle 5 via the stop element 7 into its starting position in which the sealing seat is closed.
- the armature 6 is based on a cylindrical basic shape 20 with a through hole 21, the armature 6 being guided on the through hole 21 on the valve needle 5.
- the basic shape 20 of the armature 6 has a length 24 between a first end face 22 of the armature 6 facing the inner pole 3 and a second end face 23 of the armature 6 facing away from the inner pole 3.
- the armature 6 is arranged in an armature space 16.
- the first end face 22 adjoins a first area 17 of the armature space 16.
- the second end face 23 adjoins a second region 18 of the armature space 16.
- fuel can be passed through the armature over at least part of its length 24 through at least one fluid channel 15.
- the armature 6 has a spring receptacle 25.
- the fluid channel 15 here includes the spring receptacle 25.
- the fluid channel 15 thus leads at least over part of the spring receptacle 25.
- the spring receptacle 25 is open on the end face 22 of the armature 6.
- a spring support surface 26, on which a spring 27 partially arranged in the spring receptacle 25 is supported, is formed by the base 26 of the spring receptacle 25.
- the spring 27 is also supported on the stop surface 7 ′ of the stop 7.
- the spring 27 is designed with ground spring ends 43, 44. This results in an even better print run. Furthermore, there is reduced wear and a more uniform introduction of force into the armature 6 on the spring support surface 26 on the one hand and on the stop 7 ′ of the stop element 7 on the other hand.
- a guide web 28 is formed on the armature 6.
- the guide length of the armature 6 on the valve needle 5 is equal to the length 24 of the armature 6 between its end faces 22, 23.
- valve needle 5 is guided with respect to the longitudinal axis 4 or with respect to the housing 2 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.
- the valve needle 5 can additionally or alternatively also be guided via the armature 6.
- the outside 32 of the armature 6 extends at least partially up to the inside 33 of the housing 2.
- an annular gap can then be implemented between the stop element 7 and the inner pole 3.
- the fluid channel 15 has an inclined bore 50.
- the fluid channel 15 preferably has exactly one inclined bore 50.
- the fluid channel 15 then leads over the inclined bore 50 and at least a part 51 of the spring receptacle 25.
- a direction 19 which is coaxial with respect to the longitudinal axis 4 and which is oriented from the first end face 22 to the second end face 23 results in an orientation opposite to an opening direction 52 in which the valve needle 5 is actuated when the valve 1 is opened.
- the inclined bore 50 is designed in the armature 6 such that it runs radially outward along the coaxial direction 19, i.e. away from the longitudinal axis 4, with an angle of inclination in the plane of the drawing between the coaxial direction 19 and an axis 53 of the inclined bore 50 54 results.
- the design of the inclined bore 50 is not limited to the fact that the axis 53 lies in the same plane as the longitudinal axis 4 of the valve needle 5, as is the case in the illustrated embodiment with the plane given by the plane of the drawing.
- the inclined bore 50 in this exemplary embodiment runs from the first end face 22 of the armature 6 to the second end face 23 of the armature 6.
- An advantageous hydraulic connection between the first area 17 and the second area 18 is made possible by the inclined bore 50 running from the first end face 22 to the second end face 23 of the armature 6.
- an inner part 57 of the second end face 23, on which the armature 6 and the second Stop surface 8 'interacts, corresponding to a predetermined and possibly large second stop surface 8' are given sufficiently large without the second opening 56 lying in this inner part 57 or without the fluid channel 15 intersecting this inner part 57 of the second end face 23.
- a large damping surface can be implemented between the second stop surface 8 ′ and the second end face 23.
- the inclined bore 50 is advantageously intersected over an entire length 58 of the spring receptacle 25 along the longitudinal axis 4 with the spring receptacle 25, the result is a favorable flow behavior and a first opening 55 of the fluid channel 15 which is still enlarged with respect to the spring receptacle 25
- Point 60 at which the first opening 55 is radially maximally spaced from the longitudinal axis 4, still outside the spring receptacle 25.
- points 62, 63 result at the second opening 56, the point 62 being at a maximum distance from the longitudinal axis 4 on the edge of the second opening 56 and the point 63 being minimally spaced from the longitudinal axis 4 on the edge of the second Opening 56 is located.
- the point 62 viewed radially, is further away from the longitudinal axis 4 than the point 60.
- the point 63 of the second opening 56 viewed radially, is further away from the longitudinal axis 4 than the point 61 on the edge of the first opening 55.
- the inclined bore 50 is also designed such that the bottom 26 of the spring receptacle 25 is cut by the inclined bore 50.
- the spring receptacle 25 can advantageously be used to guide the fuel through and can be integrated into the fluid channel 15 over its entire length 58.
- Fig. 2 shows a valve 1 in a partial, schematic sectional view corresponding to a second embodiment.
- the second opening 56 or a partial surface 56 ′ on the second end face 23 of the armature 6 in which the second opening 56 lies is oriented perpendicular to the axis 53 of the inclined bore 50.
- the partial surface 56 'of the armature 6 can be designed here via a circumferential groove 85 or individual countersunk bores.
- the partial surface 56 ′ can first be configured on the second end face 23 of the armature 6, and then the inclined bore 50 can be drilled starting from the second end face 23. This enables a drill tip to strike the partial surface 56 'of the armature 6 at right angles.
- a production-optimized modification to that based on FIG Fig. 1 described first embodiment which is used in particular to improve drilling. This can also prevent a drill from breaking, since drilling does not take place at an angle to a surface.
- Fig. 3 shows a valve 1 in a partial, schematic sectional view according to a third embodiment.
- a bevel 66 is configured on armature 6, which bevel cuts second end face 23 at its outer diameter 42.
- the bevel 66 then lies between the second end face 23 and the outer side 32 of the armature 6.
- the bevel 66 is preferably designed at right angles to the axis 53 of the inclined bore 50.
- this refinement has the advantage that production optimization is achieved, as can be seen from FIG Fig. 2 is described.
- the inner part 57 of the second end face 23, on which the armature 6 interacts with the stop surface 8 ' can be configured to be maximally large. This results in particularly great design freedom. In the respective application, a very large hydraulic damping can therefore be achieved.
- Fig. 4 shows a valve 1 in a partial, schematic sectional view according to a fourth embodiment.
- the fluid channel 15 has a first coaxial blind hole 71 and a second coaxial blind hole 72.
- the first coaxial blind hole 71 runs from the first face 22 in the coaxial direction 19.
- the second coaxial blind bore 72 runs from the second face 23 counter to the coaxial direction 19.
- An intersection area 73 can here be arranged close to the bottom 26 of the spring receptacle 25 when viewed along the longitudinal axis 4. This results in favorable flow conditions.
- the blind bores 71, 72 and at least a part 51 of the spring receptacle 25 can then be used.
- the spring receptacle 25 can advantageously be at least partially integrated into the fluid channel 15.
- the fluid is guided radially outward along the longitudinal axis 4, viewed in the coaxial direction 19. This also results in an advantageous introduction of the fluid starting from the inner bore 31 of the Inner pole 3 in the fluid channel 15 and at the same time advantageous damping on the second stop element 8.
- a point 60 of a first opening 55 of the fluid channel 15 that is radially as far outward as possible from the longitudinal axis 4 is closer to the longitudinal axis 4 than a point 62 of a second opening 56 of the fluid channel 15 that is radially as far outward as the maximum from the longitudinal axis 4. It is also advantageous if a centroid 64 of a first opening 55 of the fluid channel 15 is closer to the longitudinal axis 4 than a centroid 65 of a second opening 56 of the fluid channel 15.
- the fluid channel 15 exits at an exit surface 80 of the armature 6 to the second region 18 of the armature space (16), with an axis 81 of the fluid channel 15, along which the fluid channel 15 at the exit surface 80 of the armature 6 exits, is oriented perpendicular to the exit surface 80.
- This makes it possible, inter alia, to design the fluid channel 15 from this side with a bore that can be made in the armature perpendicular to the exit surface 80, which improves the manufacturability.
- the exit surface 80 can lie in a circumferential annular surface 82 with respect to the longitudinal axis 4, the annular surface 82 being configured as a partial surface 82 of a conical jacket 83 which is rotationally symmetrical with respect to the longitudinal axis 4 or as a partial surface 82 of a circular disk 84 oriented perpendicular to the longitudinal axis 4. This is possible, for example, by designing a circumferential groove 85 or a bevel 66.
