Description of the invention (/) The present invention relates to a type of citation according to the first item of the patent application scope. 〆 A solenoid valve for controlling an injection valve of an internal combustion engine. For example, in order to control the fuel pressure in the pressure chamber of an injection valve of an injector (Injektor) of, for example, a common-rail injection device, such a type (for example, German patent DE 194 08 104 A1) solenoid valve. The fuel pressure in the control pressure chamber is used to control the movement of a valve piston, which is used to open or close an injection opening of the injection valve. This conventional solenoid valve has an electromagnet provided in a housing portion. A movable armature, and a "control valve element" (which applies force in the closing direction with a "close spring" of the element and the solenoid valve), the control valve element cooperates with a valve seat of the solenoid valve, and The fuel flow from the control pressure chamber is thus controlled. This type of solenoid valve, if its armature plate is integrated with the armature pin, has a conventional disadvantage: the so-called "armature bounce" (Ankerprellen). When the magnet is OFF, the armature and the "control valve element" are accelerated toward the valve seat by the "close spring" of the solenoid valve to close a "fuel outflow channel" coming out of the control pressure chamber. As a result of the "control valve element" bounce on the valve seat, it may cause adverse vibration on the valve seat and / or bounce of the control valve element on the valve seat, which may adversely affect the control of the injection process. Therefore, in the solenoid valve published in German patent DE 109 08 104 A1, the armature is made in two parts, which has an armature pin and an armature plate (which is slidably supported on the armature pin). Top), so when the control valve element rebounds on the valve seat, the top of the armature plate continues to move against the stress of a return spring. The return spring then returned the armature piece to its 4 paper sizes on one of the stops of the armature pin. The paper size applies to the Chinese National Standard (CNS) A4 (210 X 297 mm) -------- ------------- Order --------- line (please read the notes on the back before filling out this page) 575715 A7 _______B7 ___ 5. Description of the invention (T " /) Initially set. 〆Of course, using the two-part design of the armature, the inertia is effectively stopped and reduced, and the kinetic energy that causes bouncing on the valve seat is reduced, but after the solenoid valve is closed, the armature plate will be on the armature pin. The unfavorable way is "post vibration". Because the control of the solenoid valve can cause a certain amount of injection only when the armature plate no longer vibrates, some measures are needed to reduce the armature plate's post-vibration. This is particularly necessary to describe, for example, the short time interval between a "front injection operation" and a "main injection operation". In DE 197 008 104 A1, an “over-travel stop” (tlberhubanschlag) is used for this purpose in the form of an “over-travel adjustment disk”, which is placed on the slider, and the over-travel adjustment disk limits the length of the path.俾 The armature plate can be moved on the armature pin. The over-travel adjusting disc is fixedly positioned in the solenoid valve housing between the armature plate and a slider (which guides the armature pin). When the armature plate approaches the over-travel adjustment disk, a hydraulic buffer space is formed between two flat sides of the armature plate facing each other and the over-travel adjustment disk. The fuel contained in this buffer space generates a force that counteracts the movement of the armature plate. Therefore, the rear vibration of the armature plate is greatly buffered. In the conventional solenoid valve, when the solenoid valve is installed in the housing of the solenoid valve, it is necessary to adjust the required "over-stroke" (tjberhub) of the armature plate. Thickness adjustment ~ path. After the control valve element is placed on the valve seat, the armature plate can be restored against the force of the return spring. There is a disadvantage here: the over-travel adjusting disk must be installed in a complicated manner below the return spring of the armature plate. For this reason, China National Standard (CNS) A4 specification (210 X 297 mm) is applied to 5 paper sizes. '--- --------------------- Order --------- Line (Please read the precautions on the back before filling out this page) 575715 A7 B7 V. Description of the invention (j) The over-travel adjustment disk needs a complicated structure with a keyhole-shaped opening. Since the stroke adjustment disc also affects the distance between the pole face of the electromagnet and the armature plate, when the thickness of the stroke adjustment disc is changed, the remaining air gap is also affected, which makes installation more difficult. [Advantages of the present invention] The solenoid valve of the present invention, which has the characteristic point of the first item of the patent application scope, can avoid the disadvantages occurring in the background art, and can make the installation of the armature group much simpler. The armature can be advantageously installed with the armature plate, the armature pin, the return spring and the intermediate piece outside the installation line of the injection valve, and the armature plate can be mounted on the armature pin by selecting the thickness of the intermediate piece Make adjustments to the required travel path or "overtravel path" outside the injection valve. When the axial length of the armature plate, slider and armature pin is known, the correct thickness of the intermediate piece can be obtained. The pre-assembled armature is then built into the solenoid valve housing. During installation, the maximum opening stroke of the armature pin can also be adjusted using an adjusting disc between the slider and an inner shoulder of the solenoid valve housing. Advantageous embodiments and further features of the present invention can be achieved by using the features in the appendix of the scope of patent application. It is particularly advantageous to design the intermediate part in the form of a sickle-shaped (meniscus) disc, which is pushed onto the armature pin from the side. • A safety box pushed onto the slider can advantageously prevent the meniscus from sliding away from the armature pin. The safety box can advantageously be fixed to the slide by means of a snap-in element.

Description of the invention (I) Apply force to the closing direction, so when the solenoid is not excited, the control valve element (25) leans against the valve in the closing direction. Seat (24), and closed the control pressure chamber (14) to the pressure relief chamber (19) side, so in this process, the "inflow channel" can quickly establish a high pressure, which also exists in the high-pressure fuel storage In the device, through the surface on the front side (13), the pressure generates a closing force in the control pressure chamber (14) to act on the valve piston (6) and the valve needle connected to it. This force is compared with the other The force in the lateral opening direction is large, and the force in the opening direction is caused by the existence of high pressure. If the solenoid valve is opened so that the control pressure chamber (14) is opened toward the pressure relief chamber (19), The pressure in the small volume of the pressure chamber (14) is quickly dissipated, because the control pressure chamber is (15) The reason for decoupling from the high pressure side. Therefore, the force caused by the high pressure of the fuel on the valve needle (which acts on the valve needle in the open direction) is dominant, so the valve needle is also moving upwards and therefore The at least one injection opening is opened to inject fuel. However, if the solenoid valve (30) closes the "fuel outflow passage" (17), the pressure in the "control pressure chamber" (14) will be subject to the passage " The fuel flowing after the "inflow channel" (15) is established again, so the original closing force is generated and the valve needle of the fuel injection valve is closed. When the solenoid valve is closed, the "close spring" of the armature pin (27) (31) The control valve element (25) is pressed against the valve seat (24) in a pulsating manner. An unfavorable rebound (Abprellen) or post-vibration effect of the control valve element is caused by the following manner: the armature pin strikes The valve seat is caused to undergo elastic degeneration. This elastic deformation has the effect of storing energy. Among them, a part is transmitted to the control valve element, which then rebounds away from the valve with the armature pin.

Description of the Invention (p) The conventional electromagnetic shown in this figure uses a two-part armature, which has an armature that is decoupled from the armature pin (27) In this way, the total inertia acting on the valve seat (24) can be reduced, but the armature plate (28) will post-vibrate in an unfavorable manner. Therefore, it is known here that the solenoid valve design There is an "overtravel adjustment disk" (70) (shown in Figure 1), which is located between the armature plate (28) and the slide box (24). Figure 1 shows when the solenoid (29) is turned off. Closed solenoid valve. The over-travel adjusting disc (70) has a complicated keyhole-shaped opening (71) to pass through the power supply armature pin. This opening (71) is necessary, and the armature pin (28) can be attached to the joint neck during installation. Move through this opening (71) and push the meniscus disk (26) onto the armature pin. The over-travel adjustment disc limits the movement path of the armature plate (28) on the armature pin (27) to an amount of d. The back vibration of the armature plate (28) is reduced by the over-travel adjustment disk (70), and the armature plate (28) returns to it more quickly at the stop portion (26) [the stop portion design Into a meniscus disk form], the adjusting disk (38), the flange (32) of the slider (34) and the over-stroke adjusting disk (70) are clamped into the solenoid valve housing to become a fixed position. . The thickness of the over-travel adjusting disc (70) also affects the distance of the armature plate (28) from the electromagnet (29). The manufacture of the solenoid valve and the manufacture of the injection valve provided with the solenoid valve are relatively expensive and complicated. Fig. 2 shows an embodiment of a solenoid valve according to the present invention. Identical parts are indicated by the same reference numerals. In the solenoid valve of the present invention, the maximum opening stroke of the armature pin (27) is adjusted using an adjustment disk (38). Slider (34)-as in the prior art, a surrounding flange (32) is used to clamp the surrounding edge (41) of the casing portion (60) and the "clamping shoulder portion" of the casing portion (4) ”(42), there is an adjusting disc (38) and another adjusting disc (70a) between the sliding part (34) and them. 13 This paper size is applicable to China National Standard (CNS) A4 (210 X 297 mm) ------------- Fee -------Order --------- Line (Please read the precautions on the back before filling this page) 575715 A7 ____B7_______ 5. Description of the Invention (tI) The adjustment disc is used to adjust the interval between the pole surface of the electromagnet (29) and the armature plate (28), but the over-travel path of the armature plate (28) is the same as the first The conventional solenoid valve shown in the figure is different and is not adjusted by the dial (70a). In order to explain the present invention more clearly, the armature group [has an armature plate (28), an armature pin (27), a return spring (35), an intermediate piece (50), and a slide piece (34)] is shown in FIG. 3 Zoom in icon. The installation of this armature group can be advantageously performed outside the casing of the injection valve. The armature pin (27) shown in Fig. 3 is different from that in Fig. 2 in that its position corresponds to the position where the solenoid valve is fully opened and the armature plate (28) is attracted by the electromagnet (29). The armature plate (28) is pressed against a stopper (26a) on the armature pin (27) by a return spring (35). The stopper is formed by a surrounding protrusion. The armature pin (27) is An end of the axial slider has an annular shoulder (33) which faces the slider and stops on an intermediate piece (50) which is pushed onto the armature pin. The middle piece (50) is supported on an annular stop surface (37) of the sliding piece (34). With the stop function of the annular shoulder (33) on the stop surface (37) and the middle piece (50) placed in the middle, the maximum opening stroke of the armature pin (27) when the solenoid valve is opened And the maximum opening stroke of the associated control valve element (25) is limited. The middleware can be designed as a one-part or several-part 'and especially a disc-shaped one. In the embodiment shown here, the intermediate piece is designed as a meniscus, as shown in Figures 4 and 5. By using the distance of the side edges (51) and (52) facing away from each other or the thickness (C) of the meniscus plate (50), the overtravel path (d) of the armature plate can be adjusted. The inner diameter (g) of the meniscus disk is designed to be slightly larger than the groove diameter of an annular groove (44) of the armature pin (27), and the meniscus disk (50) is pushed into the annular groove. The size of the annular groove (44) is so large that the width of the annular groove is often larger than all of the relevant 14 meniscus discs.

DESCRIPTION OF THE INVENTION (| λ) The thickness C is larger. The axial length a of the armature plate. The axial length b of the slider and the axial length f of the armature pin from the first stop (26) to the annular shoulder (33) can be measured. From the relationship of the formula f = a + b + c + d + e or the formula d + e = fabc in another way, the conversion of d + e can be determined by the thickness of the meniscus, because a, b, And c are known. d + e 値 corresponds to the sum of the maximum open stroke (e) of the armature pin and the maximum over-travel path (d) from the armature plate to the stop surface (36). If the maximum open stroke (e) to be adjusted is preset, the over-travel path (d) of the armature plate (28) can be determined in accordance with the thickness or the thickness (c) of the meniscus plate (50). Precisely adjusted when the pivot group is pre-installed. The meniscus (50) pushed onto the armature pin is secured in its radial position by a cassette (80). The box (80) is shown in Figs. 6 and 7. The inner diameter of the box (80) is larger than the outer diameter (h) of the meniscus plate (50). One end of the box (80) is provided with a rib that projects inwardly ( 83). The recess (82) extending in the axial direction is used to form an engaging element (81) on the cassette (80). As shown in Figures 2 and 3, the box (80) is pushed onto the slider (34)-the joint neck (45) [the joint neck faces away from the stop surface (36)]-until the engaging element (81 ) Until it snaps into the recess (46) on the outer shell of the joint neck (45). Here, the box (80) slides through the meniscus plate (50), and the plate (50) is accommodated so that the meniscus plate (50) is secured on the armature pin (27) Radial position. The pre-assembled armature assembly of Fig. 3 is embedded in the valve housing as shown in Fig. 2. The thickness of the adjusting disc (38) is selected so that the predetermined maximum opening stroke between the "control valve element" (25) and the valve seat (24) is accurately maintained. At this time, the interval between the armature plate (28) and the electromagnet can also be adjusted via the adjustment plate (70). 15 This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) — " -------------------- Order ------ --- Wire (please read the sounds on the back?

In this way, in the magnetic valve of the present invention, the stop surface (36) is advantageously designed in the form of a flat surface. Comparison of the solenoid valve shown in Figure 1 [wherein the armature plate is provided with an open (71) Adjusting disk (70)], the magnetic valve in Fig. 3 can achieve better cushioning. The doctor can design a larger crack seam. Obviously, it can also be combined with the embodiment shown here. Somewhat different, the middleware is composed of several disks. Non-disk-shaped middleware can also be considered. If the middleware is fixed to the armature pin in a form-fitting manner, the safety box can be omitted.
