Definitions
- the present invention relates to a
- WO-A-03/095825 discloses an injector for fuel injection in which an annular gap is formed between an injector body and a throttle module used as a separate component. To seal this annular gap, plastically deformable cutting edges are provided on the throttle module, which are pressed onto steps in the injector housing during assembly of the throttle module.
- a control chamber is delimited on one side by a spring plate which is arranged loosely, ie not sealingly, in a bore in a nozzle body.
- This spring plate is pressed against a counter body by the pressure prevailing in the high pressure chamber of the valve and the force of a spring.
- the present invention has for its object to provide a fuel injector of the type mentioned, in which the manufacture and installation of the control body in the housing is simpler and thus less expensive than the known fuel injectors.
- control body is no longer pressed into the housing as in the prior art, but is inserted loosely and not sealingly into the opening in the housing. This enables the control body to be easily installed and removed. Furthermore, the control body can be manufactured more cost-effectively, since the dimensional accuracy and the machining quality do not have to be so demanding.
- the sealing of the high-pressure chamber from the low-pressure chamber is ensured on the one hand by the interaction of sealing surfaces on the control body and on the holding body and on the other hand by the application of a further sealing surface on the holding body to a seat surface formed on the housing.
- 1 is a longitudinal section of a fuel injection valve
- FIG. 3 shows a partial section of the representation according to FIG. 2 in longitudinal section and on an enlarged scale compared to FIG. 2, and
- Fig. 4 is a perspective view of the holding body of the fuel injector shown in Figs. 1-3.
- the fuel injector 1 shown schematically in longitudinal section in FIG. 1 has a housing 2, which is formed by an upper housing part 2a and a valve seat element 2b.
- the valve seat element 2b is tightly connected to the upper housing part 2a by means of a holding element 3 designed as a clamping nut.
- the valve seat element 2b has a valve seat 4 and injection openings 5.
- This high-pressure chamber 7 is connected to a high-pressure fuel inlet 8 and extends to the valve seat 4.
- an injection valve member 9 which is designed as a valve needle and is coaxial with the longitudinal axis A of the housing and which cooperates with the tip of the valve seat 4 in the closed position shown in FIG.
- the injection valve member 9 is lifted off the valve seat 4 by means of a hydraulic control device 10, the construction of which will be explained in more detail with reference to FIGS. 2 and 3.
- the injection valve member 9 is guided with a section designed as a guide 9a by means of a close sliding fit in the valve seat element 2b.
- the injection valve member 9 is provided in the area of this guide 9a with contact surfaces.
- the injection valve member 9 is pressed down by a closing spring 11 in the closing direction.
- the closing spring 11 is supported at its lower end on a support ring 12 which rests on a shoulder 13 on the injection valve member 9. At the other end, the closing spring 11 is supported on a spacer sleeve 14 surrounding the injection valve member 9.
- the relatively long, hollow cylindrical spacer sleeve 14 spans the region of the confluence of the high fuel pressure inlet 8 into the central bore 6 and is guided at its ends by means of guide surfaces 15, 16 on the wall of the bore 6 (FIG. 2).
- the play between the guide surface 15, 16 and the wall of the bore 6 is between 1/100 and 1/10 mm.
- the spacer sleeve 14 has a smaller diameter, so that an annular space 17 is formed between the wall of the bore 6 and the outer circumference of the spacer sleeve High-pressure fuel inlet 8 communicates.
- the spacer sleeve 14 is provided with passage openings 18 through which fuel can pass from the annular space 17 into the interior of the spacer sleeve 14.
- a stop shoulder 19 is formed in the housing 2, which serves as a stop for the spacer sleeve 14 when the latter is displaced upwards and is intended to cooperate with a stop surface 20 formed at the lower end of the spacer sleeve 14 (FIG. 2).
- the spacer sleeve 14 presses against a hollow cylindrical guide sleeve 21 belonging to the hydraulic control device 10, which is guided at the upper end by means of a guide surface 22 in the central bore 6.
- An annular space 23 is present between the guide sleeve 21 and the wall of the bore 6, which is connected to the interior of the spacer sleeve 14 via passages 24, which are provided at the lower end of the guide sleeve 21 or at the upper end of the spacer sleeve 14, and to the high-pressure chamber 7 heard.
- the injection valve member 9 has a double-acting control piston 25, which is guided in the guide sleeve 21 in a narrow sliding fit.
- the control piston 25 is acted upon on its underside by the high-pressure fuel in the high-pressure chamber 7 and delimits with its top side a control chamber 26 which is delimited laterally by the guide sleeve 21.
- In the guide sleeve 21 there is an intermediate valve body 27, which in the direction the longitudinal axis A is displaceable and has a lower end face 27a.
- the intermediate valve body 27 is guided in the guide sleeve 21 with a play of typically 0.03 to 0.2 millimeters.
- a throttle passage 31 coaxial with the longitudinal axis A extends in the intermediate valve body 27 and extends between the lower and upper end faces 27a, 27b of the intermediate valve body 27.
- a spring element 28 is arranged in the control chamber 26, which is supported on the one hand on the intermediate valve body 27 and on the other hand on a support element 29 which rests on an annular shoulder 30 on the guide sleeve 21 (FIG. 3).
- the spring element 28 surrounds a central one
- the intermediate valve body 27a of the intermediate valve body 27 is arranged at a distance a from the upper side 29a of the support element 29 (see FIG. 3).
- the support member 29 serves as the movement of the
- the support element 29 could also be in one piece with the guide sleeve 21 and with the latter as one
- the intermediate valve body 27 bears against a lower end face 32a of a control body 32, which serves as a sealing surface and is arranged loosely, ie not sealingly, in the central bore 6.
- the lower end face 32a of the control body 32 together with the upper side 21a of the guide sleeve 21, seals the control chamber 26 from the high-pressure chamber 7.
- the control body 32 lies with a upper end face 32b on the underside 33a of a holding body 33.
- the holding body 33 is screwed into a recess 35 in the housing 2 by means of an external thread 34.
- the holding body 33 is provided with countersunk holes 36 which are used to insert a tool for screwing in and tightening the holding body 33 (see also FIG. 4).
- the holding body 33 is screwed so tightly into the housing recess 35 that it rests with a first annular sealing surface 37 formed on its underside 33a on a seat surface 38 which is formed on the bottom of the recess 35 in the housing 2 and surrounds the central bore 6.
- a second, also annular sealing surface 39 adjoins this first sealing surface 37 of the holding body 33, which lies in the same plane as the first sealing surface 37.
- a sealing surface 40 formed on the upper end face 32b of the control body 32 bears against this second sealing surface 39.
- the sealing surfaces 37, 38, 39 and 40 preferably seal close to the circumference of the bore 6.
- the sealing surfaces 37 and 39 of the holding body 33 are advantageously formed on a single flat end surface of the holding body 33.
- the control body 32 has a continuous control passage 41 which runs coaxially to the longitudinal direction A and has a throttle constriction 42 at its end opening into the upper end face 32b of the control body 32.
- the control passage 41 is in hydraulic connection with the throttle passage 31 in the intermediate valve body 27.
- the sealing surface 40 on the upper end face 32b of the control body 32 surrounds the control passage 41.
- Passages 43 are also formed in the control body 32, which are laterally offset from the control passage 41 and which open into the lower end face 32a of the control body 32. At the other end, the passages 43 are connected to an annular groove 44 on the outer circumference of the control body 32, which is connected to the annular space 23 and in which the high fuel pressure therefore prevails.
- the passages 43 are closed by the intermediate valve body 27, which is pressed with its upper end face 27b against the lower end face 32a of the control body 32.
- an electromagnetically actuated pilot valve 45 is accommodated in the housing 2, which has a displaceable valve stem 46 and a closure body 47 which is separate therefrom and which rests between the injection processes on the upper end face 32b of the control body 32 serving as the valve seat surface Control passage 41 closes.
- a pilot valve spring 48 acts on the valve stem 46 and thus also on the closure body 47, which presses the closure body 47 against the upper end face 32b of the control body 32.
- an electromagnet arrangement 49 which consists of a magnet body 50 with a magnet coil 51 and a magnet armature 52.
- the valve stem 46 is fixedly connected to the magnet armature 52 and is displaceably guided in the magnet body 50.
- the holding body 33 also has a central bore 53 (see also FIG. 4) in which the valve stem 46 runs and in which the closure body 47 is guided.
- a stop shoulder 54 projects into this central bore 53 and engages in an annular groove 55 on the valve stem 46. The stop shoulder 54 serves to limit the stroke of the valve stem 46 when the electromagnet arrangement 49 is excited.
- the maximum possible stroke b of the valve stem 46 is smaller than the distance c between the magnet armature 52 and the magnet body 50, so that even when the pilot valve 45 is open Magnet armature 52 does not abut the magnet body 50.
- the stop shoulder 54 for the valve stem 46 lies outside the effective magnetic field of the electromagnet arrangement 49.
- valve stem 46 In order to be able to insert the valve stem 46 into the holding body 33, the latter is provided with an eccentrically arranged recess 56 which is open towards the central bore 53.
- the valve stem 46 is inserted laterally offset into the recess 56 with respect to the axis of the central bore 53. If the annular groove 55 of the valve stem 46 is at the level of the stop shoulder 54, the valve stem 46 is displaced in the transverse direction into the central bore 53.
- the closure body 47 which is guided loosely in the bore 53, serves to precisely adjust the stroke b of the valve stem 46.
- the size of the stroke b can be precisely determined by inserting a closure body 47 of a certain height. If such an exact adjustment should not be necessary - which can be the case, for example, with a different configuration of the stroke limitation of the valve stem 46 - the closure body 47 can be omitted.
- the control passage 41 is directly through closed the valve stem 46, as is known for example from EP-A-1 273 791.
- the lower, spherical end 46a of the valve stem 46 acts on the flat upper end surface 47b of the closure body 47 (FIG. 3).
- the upper end surface 47b of the closure body 47 could be spherical and interact with a flat end surface 46a of the valve stem 46. In both cases, the tightness of the pilot valve 45 is improved.
- the central bore 53 and the recess 56 in the holding body 33 belong to a low-pressure chamber 57, which is connected to the flow with a low-pressure outlet 58 (FIGS. 1 and 2). From this low pressure outlet 58, a line (not shown) leads back to a fuel reservoir.
- the closure body 47 is provided with longitudinal grooves 47a which, when the closure body 47 is lifted off the control body 32, allow fuel to flow from the control passage 41 into the low-pressure chamber 57.
- Control body 32 can get past the low-pressure space 57, the first sealing surface 37 of the holding body 33 screwed into the housing 2 is pressed in a sealing manner against the seat surface 38 in the housing 2.
- Control body 32 pressed by the fuel pressure in the high pressure chamber 7 with its sealing surface 40 against the other sealing surface 39 on the holding body 33.
- the surface quality of the sealing surfaces 37, 39 and 40 and the seat surface 38 are not particularly demanding. It can it is sufficient to grind these surfaces in order to achieve a sufficient sealing effect, because the sealing effect does not have to be one hundred percent. Expensive post-processing steps are therefore not absolutely necessary. If a 100 percent sealing effect is necessary or desirable, it can be achieved with finely lapped surfaces. However, if the leakage is substantially smaller than the amount of fuel discharged via the control passage 41 (for example 10% of the latter or less), the leakage generally plays no role.
- the mode of operation of the fuel injection valve 1 shown in FIGS. 1-3 is as follows: The starting point is the state shown in these figures, in which the injection valve member 9 is in the closed position and the intermediate valve body 27 lies sealingly against the control body 32. The electromagnet arrangement 49 is not energized and the closure body 47 closes the control passage 41. The pressure in the control chamber 26 is the same as in the high-pressure chamber 7.
- An excitation cycle is triggered by energizing the electromagnet arrangement 49.
- the magnet armature 52 is pulled against the magnet body 50, which has the consequence that the valve stem 46 lifts off the closure body 47.
- the closure body 47 can now move upward under the effect of the fuel pressure in the control passage 41 and releases the control passage 41.
- the control passage 41 and thus also the control chamber 26 are now connected to the low pressure chamber 57.
- the pressure in the control room 26 begins to decrease.
- the injection valve member 9 thereby moves away from the valve seat 4 and opens the injection openings 5.
- the injection process begins. In this case, fuel from the control chamber 26 through the Throttle passage 31 and the control passage 41 displaced into the low pressure space 57.
- the intermediate valve body 27 remains in contact with the control body 32.
- the opening stroke of the injection valve member 9 is, for. B. limited by the fact that the projection 25a of the control piston 25 comes to rest on the intermediate valve body 27.
- the electromagnet arrangement 49 is de-energized to end the injection process. The result of this is that, under the force of the pilot valve spring 48, the valve stem 46 and with it the closure body 47 are moved downward until the closure body 47 comes to rest on the control body 32. The mouth of the control passage 41 on the low-pressure side is closed again by the closure body 47. The pressure in the control passage 41 begins to rise. This, together with the fact that the high fuel pressure prevails in the passages 43 in the control body 32, leads to the intermediate valve body 27 moving away from the sealing abutment on the control body 32.
- the downward movement of the intermediate valve body 27 is ended by striking the upper side 29a of the support element 29 , Because the passages 43 in the control body 32 are opened by moving the intermediate valve body 27 away from the control body 32, fuel can be refilled under high pressure through these passages 43 and the throttle passage 31 and along the entire circumference of the intermediate valve body 27, which results in the closing process of the injection valve member 9 greatly accelerated. As soon as the injection valve member 9 rests against the valve seat 4 and closes the injection openings 5, the injection process is ended. Immediately thereafter, the intermediate valve body 27 is moved back into its sealing position under the force of the spring element 28. The fuel injection valve 1 is now ready for the next injection process.
- the spacer sleeve 14 transmits the force of the closing spring 11 to the control body 32 via the guide sleeve 21.
- the injection valve member 9 is inserted into the valve seat element 2b with the closing spring 11 and slipped-on spacer sleeve 14, this subassembly is introduced into the upper housing part 2a and fastened to the upper housing part 2a by means of the holding element 3.
- the stop shoulder 19 in the upper housing part 2a limits the insertion path of the spacer sleeve 14 in the central bore 6, which considerably simplifies the assembly of the control body 32.
- the support element 29 serves as a stop for the intermediate valve body 27, as a result of which the opening path of the intermediate valve body 27 is limited. This brings advantages for pre-injections with short intervals.
- control body 32 loosely in the central
- the fuel is supplied to the valve seat 4 via the central housing bore 6.
- the particular constructive solutions described can also be used in fuel injectors in which the fuel is supplied to the valve seat via a feed channel which is laterally offset with respect to the longitudinal axis A of the housing, such as from the US-A-5,775,301 is known.
