In addition, the fuel is discharged from the fuel tank; the heat of the fuel injection module can be discharged into the fuel tank. "The flow of the pump material can be realized with a small pressure loss. According to another preferred design, the ring The pump anchors are arranged substantially vertically, in this case' The bubbles that may exist in the oil can pass through the wrong parts during the ascending process and enter the fuel tank. When the fuel passes through the pump anchor, it is heated by the waste heat of the electromagnetic coil absorbed by the pump, thereby further enhancing the removal of the hot fuel. Gas action. This fuel circulation also ensures that the fuel oil is always cold fuel to the fuel injection module. The preferred design of the ring ΓΓ 'flat adjuster for the air conditioner is designed to ensure that the magnetic flux enters the flat tin piece axially. The J-shaped flat anchor can also make the fuel in the group. The air (4)...the soil is in the middle of the 4th through the injection mold. The 诵:!

According to another method of the invention, the zinc anchor is a 5-leaf solution, and the flat anchor is fixed by the resetting at the fuel injection module. Red, 'B λ is on. The return spring is preferably an annular disc spring that fixes the flat anchor to the outer casing. From the &&&&#; see the connection between the 'I room and the suction room' The passage is preferably arranged below the dead point of the upper side of the pump piston. In this case, when the pressure recovery phase of the oil pump starts, the pressure cannot be immediately recovered within the enthalpy, but the gas that may exist by the connecting passage is present. The pump chamber is discharged into the suction chamber. The n-piston can also be accelerated to its target speed because at the beginning of the pressure recovery phase, only the small liquid-dust reaction force generated by the fuel is present. After the connecting passage is closed by the piston, the sheet metal phase. 7 to the beginning of the real reconciliation 7 201002936 In order to maximize the structure and reduce costs, the connection between the pump chamber and the suction chamber is preferably arranged in the annular channel area below the suction chamber.

As shown in Fig. 2, the air adjusting seat 43 and the plenum 45 are provided. __ 'The flat material 23 is sealed to the outer casing 25, and the second reset: - the return spring 28 fixes the spring. For example, the second reset == 25 is between the cover 24. The seal is attached to the housing by a clamping member. The sealing seat 43 is provided with a plurality of through holes 5b52 and 53u which are more detailed in Figs. 3 and 4, and are divided into annular through holes 51, 52, and 53. The inner side of the brother 52 is defined by the "outer outer ring 55". The outer ring (4) and the outer 55 actually constitute the sealing surface for the sealing material of the flat 11 201002936. The through hole Mu is deeper than the inner ring 54 and the outer 璟μ with the area between the & a slightly n,, B ± " on the 岔 cover, so when the flat anchor 23 祜 open % 'open 3 is 4 @ 1 and outside The entire ring # between the exhibitions 55 is shown in Fig. 2, and the plenum chamber 4 is sectioned. Yajia At H Puppy 10 1 field piece 2 3 below, it is true that your giant field piece η can be opened when the coil 21 is energized. A connection passage 36 is also disposed between the suction chamber 30 and the pump officer 'H^. The connection passage 36 is connected to the suction chamber 3, and the garment-shaped passage region 30a is in communication. Wherein, the connecting passage 36 includes an opening 35a on the bank of the cylinder liner 3 and an opening 25b in the flange portion 25c of the outer casing 25. The white is connected, and the Z-X is seen from the axial X-X of the simmering oil module, and even 36 is slightly lower than the dead point on the upper side of the piston 26. In this way, the seam type gas can be realized by: the dust recovery of the dust force, because only when the piston % 疋 over the connecting passage 36, the connecting passage is closed by the side wall of the piston %: the pressure can be realized in the fruit chamber 29 restore. Among them, the piston % constitutes a control edge toward the pressure surface 26b of the pump chamber 29. The function of the fuel injection module of the present invention is as follows. Figure 2 shows the piston at the end of the suction stroke. In this state, the coil 21 is energized, thereby moving the flat tin member 23 in the direction of the arrow a, and the annular spring pin member 22 is moved in the direction of the arrow b. It should be pointed out here that depending on the specific current intensity, it is also possible to move only by the flat i-piece 23, thereby opening the air regulator view, and the oil is not manipulated. However, when the current intensity is sufficiently large, the air conditioner 2〇d and the oil pump 2〇a are under-operated, thereby moving the flat fault member on the one hand, and the ring pump anchor 22 in the direction of the arrow B on the other hand. motion. In this case, the piston 26 is also moved in the direction of the arrow b by the bow 3丨. However, when the compression stroke begins, no pressure recovery occurs in the pump chamber 29 because the piston 26 has not passed the connecting passage 36. Only when the piston 26 has passed the connecting passage 36, the pump chamber 29 will begin to recover. 2 = Once the pressure is sufficiently high in the crucible, the check valve 33 will open against the force of the return spring 34. At this time, fuel can be injected into the oil suction pipe 8 from the pump chamber 29 by the metering valve 32. Here, the injection head can be controlled by selecting the diameter of the metering valve and the elastic force of the third return spring 34. Once the pressure in the pump chamber 29 drops again below the opening pressure, the third return spring 34 will re-feed the check valve 33 to the starting position, and the check valve 33 in the initial position is closely abutted in an integral manner. The valve housing 29 is closed on the valve seat 25a on the outer casing. At the end of the fuel injection, the energization of the coil can also be ended. The first return spring 27 then re-feeds the piston % into the starting position, during which the annular pump anchor 22 is also reset by the action of the bow 31. Once the piston % has crossed the connecting passage, the process of drawing fuel from the annular passage region 3〇a into the pump chamber 29 is started. Since the inhaled fuel is only from the annular passage zone, it is only necessary to use the filter π to carry out the actual fuel intake 37 and thus has an extremely long service life. ...Because the pump anchor 22 is axially drilled, the fuel can be supplied axially from the supply g 6a 吸入 to the 3 〇 and the pump anchor 22 to the return line. In this way, the flow of the nozzle oil module can be realized. Since the fuel flows through the m 22 of the hollow tube, the waste heat of the coil 21 can be excellently absorbed. In this case, the fuel is heated up and flows back to the tank via the return line (9). Thereby, the fuel circulation is realized during the operation of the fuel injection device, and the heat of the joint and the shell is realized by the oil return pipe. The additional effect of this measure is that if bubbles are generated when the fuel is heated 13 201002936, the bubbles can be discharged upwards simply by the substantially vertically oriented bore 22a in the pump anchor 22. Since the flat malware 23 is also annular, a return path through the center of the fuel injection module can be set. This results in a very compact structure. It should be noted here that the magnetic circuit 40 can be designed as an insert into which the magnetic circuit can be injected when the outer casing 25 is manufactured by injection molding. The cylinder liner 35 is preferably pressed into the outer α 2 5 by a press-fit process. This makes it possible to manufacture the oil module at a low cost and with a small number of parts. Figure 6 and Figure 6 show an alternative design of the flat anchor 23. The flat anchor 23, which uses a ° meter solution, also has three through holes 5, Μ, Μ. Here, the sealing seat is separated along the outer circumference of each of the through holes 5, 52, 53: the advantage of the alternative flat material is mainly that only a relatively exert force is required when opening, because the flattening is shown in FIG. 3 and FIG. In comparison, the area between the through hole 5 and 52 is not included in the area where the flat anchor is in contact with the bypass pipe 12. It should be pointed out here that depending on the specific sealing requirements of the flat tin piece 23, it is also possible to provide a plastic element, a rubber element or a sealing coating on the seal for one or two rolls of the < μ #, in order to obtain a better seal. effect. Figure 7 shows the use of the same or the same example of the oil-filling device, the number. The 11° member adopts the same elements as the previous embodiment: the first embodiment is the same as the first embodiment, and the first embodiment is the difference, as shown in Fig. 7 "different from the first embodiment" The soil 26 is provided with - along the axial direction χ χ orientation 14 201002936

The slot 5 相连 connects the pump chamber 29 to the suction chamber 30 when the piston 26 is in a partial region above the piston stroke. In this case, only when the piston 26 is moved until the groove 50 is covered by the cylinder liner 35, the connection between the pump chamber 29 and the suction chamber 3 is released, and the pressure is again restored in the pump chamber 29. This pressure recovery is extremely easy to implement, and there is no need to provide openings in the flange region 25c and the cylinder liner 35. The disadvantage is only that the total fuel volume flow has to be filtered, since it is no longer possible to filter only the fuel that is sucked into the pump chamber 20. Therefore, the oil filter must be placed in the oil supply pipe 6a. This embodiment is in other respects in accordance with the previous embodiment, so that the description given in the previous embodiment can be referred to. The above embodiments all point to a particularly dense fuel injection module 2, and the annular design of the flat anchor member 23 and the pump anchor member 22 enables axial flow of fuel in the fuel injection, and inside. This avoids heat-related problems because the fuel absorbs the heat generated by the unit during its cycle and returns it to the tank. This allows for particularly high operational reliability.
