Definitions
- the invention is based on a fuel injection valve for internal combustion engines according to the preamble of claim 1.
- a fuel injection valve for internal combustion engines according to the preamble of claim 1.
- the fuel injection valve has a valve body with a bore formed therein, which is closed on one side, the closed end being designed as a valve seat and projecting into the combustion chamber of the internal combustion engine.
- a piston-shaped valve member is arranged longitudinally displaceably in the bore and has a first radial extension at its end facing away from the combustion chamber, with which it is sealingly guided in the bore.
- the valve member merges into a valve sealing surface which interacts with the valve seat for controlling at least one injection opening.
- a second radial extension is formed on the valve member, with which it is guided in the bore.
- a pressure chamber is formed in the valve body by a radial expansion of the bore, which can be filled with fuel under high pressure and which extends up to the combustion chamber as an annular channel surrounding the valve member continues the injection ports.
- Recesses are formed through which the fuel can flow to the injection openings. Due to the guided second radial expansion of the valve member, the valve member is guided exactly in the center of the bore, and the fuel inflow from the pressure chamber to the injection openings is symmetrical, so that the fuel - if several injection openings are provided - evenly through all injection openings into the combustion chamber of the internal combustion engine is injected.
- the high pressure in the pressure chamber results in a fuel leakage oil flow from the pressure chamber through the annular channel formed between the first radial extension and the bore, despite the slight play of the first radial expansion of the valve member guided in the bore.
- This leak oil flow is fed to a leak oil chamber and from there to a leak oil system.
- the play of the valve member can be increased on one of the two radial extensions, but this is disadvantageous in both cases: If the sealing radial extension facing away from the combustion chamber is increased in the play, the result is too great Leakage oil flow from the pressure chamber of the fuel injection valve into the leakage oil chamber; on the other hand, if the clearance of the second radial extension close to the valve seat is increased, inaccuracies in the position of the valve sealing surface with respect to the valve seat occur and thus problems that should be avoided with the second guide.
- the fuel injector according to the invention with the characterizing features of claim 1 has the advantage that the combustion chamber facing away, the first radial extension of the valve member can be equipped with a larger game in the bore and thus avoiding seizure or increased friction of the valve member in the bore, without an increased leakage oil flow occurring.
- the pressure chamber is sealed by an additional valve piston, which is directed away from the combustion chamber to the valve member in the bore and rests with its end face on the valve member. It is not necessary to connect the valve piston to the valve member.
- the first guide of the valve member facing away from the combustion chamber has only a leading function and is no longer used for sealing. By separating the functions of sealing the pressure chamber and guiding the valve member, very good sealing of the valve piston in the bore can be achieved without the risk of the valve member seizing in the bore.
- the injection valve according to the invention can be connected, for example, to a known valve holding body, as is used in so-called common rail injection systems. A structural adjustment of the valve holding body is not necessary.
- the valve piston rests on the valve member through an essentially punctiform contact surface. As a result, it is advantageously possible that the position of the valve piston and valve member relative to one another can be easily shifted relative to one another due to the slight interlocking of the contact surface. The play of the guide of the valve member facing away from the combustion chamber is thus not impeded by the valve piston.
- FIG. 1 shows a longitudinal section through a fuel injection valve according to the invention and FIG. 2 shows an enlarged section of FIG. 1 in the region of the valve member.
- FIG. 1 shows a longitudinal section through a fuel injection valve which is provided for a fuel injection system based on the common rail principle.
- the exact structure of the fuel injection valve in the area of the valve body is shown enlarged in FIG.
- a valve body 1 is clamped with a clamping nut 6 in the direction of a longitudinal axis 2 of the fuel injection valve against a valve holding body 3, the end of the valve body 1 facing away from the valve holding body 3 projecting into the combustion chamber of an internal combustion engine (not shown in the drawing). It can also be provided that an intermediate disk between the valve body 1 and the valve holding body 3 is arranged.
- a bore 5 is formed in the valve body 1, which is closed at the end on the combustion chamber side and forms a valve seat 32 there.
- a piston-shaped valve member 10 is arranged to be longitudinally displaceable, which is arranged coaxially to the longitudinal axis 2 and at the end of which the combustion chamber is located, a valve sealing surface 30 is formed.
- the valve sealing surface 30 interacts with the valve seat 32 for controlling the at least one injection opening 34.
- a pressure chamber 23 which is formed by a radial widening of the bore 5 and continues towards the valve seat 32 as an annular channel surrounding the valve member 10 and connects the pressure chamber 23 to the injection openings 34.
- the pressure chamber 23 is connected via an inlet channel 21 running in the valve body 1 and in the valve holding body 3 to a fuel connection 40, via which fuel can be introduced into the pressure chamber 23 under high pressure from a high-pressure fuel source not shown in the drawing.
- the valve member 10 has two radial extensions 110 and 210, offset with respect to one another in the axial direction, with which the valve member 10 is guided in the bore 5.
- the first radial extension 110 is arranged facing away from the combustion chamber from the pressure chamber 23.
- the second radial extension 210 is arranged near the valve seat 32, so that the valve sealing surface 30 is held exactly symmetrically coaxially with the valve seat 32.
- Recesses in the form of oblique grooves 25 are formed on the second radial extension 210, through which the fuel can flow from the pressure chamber 23 to the injection openings 34.
- a pressure shoulder 13 is formed on the valve member 10 in the pressure chamber 23 at the transition to its first vertical extension 110.
- a valve piston 12 is arranged in the bore 5 facing away from the combustion chamber 10 and is sealingly guided in the bore 5.
- the valve piston 12 is longitudinally displaceable in the bore 5 and has less clearance in the bore 5 than the first radial extension 110 of the valve member 10.
- a requirement 14 is formed, which is at least approximately has the shape of a spherical section, so that a punctiform contact of the valve piston 12 on the end face of the valve member 10 facing this comes about.
- Due to the molding 14, an intermediate space 15 is formed between the valve piston 12 and the valve member 10, which is connected to the pressure chamber 23 via the annular gap 20 formed between the first radial extension 110 of the valve member 10 and the bore 5.
- the valve piston 12 is connected away from the combustion chamber to a spring plate 29 arranged in a spring chamber 28. Between the spring plate 29 and the end of the spring chamber 28 facing away from the combustion chamber, a spring 27 is arranged under prestress, which acts on the spring plate 29 in the direction of the combustion chamber.
- the spring chamber 28 continues away from the combustion chamber as a guide bore 11, in which a longitudinally displaceable piston rod 8 is arranged, which rests on the spring plate 29 at its end on the combustion chamber side. With its end facing away from the combustion chamber, the piston rod 8 delimits a control chamber 42 which is connected via an inlet throttle 44 to the inlet channel 21 and via an outlet throttle 46 which can be closed by a control element 48 and to a leakage oil chamber 50 formed in the valve holding body 3.
- the outlet throttle 46 can be closed against the leak oil chamber 50 by an electrically controllable control element 48.
- the leakage oil chamber 50 is connected via a leakage oil connection 52 to a leakage oil system, not shown in the drawing.
- the spring chamber 28 is connected to the leakage oil chamber 50 via the annular gap formed between the piston rod 8 and the guide bore 11 and via a leak oil channel 54, which is formed in the valve holding body 3, so that the fuel flowing past the valve piston 12 into the spring chamber 28 into the Leakage oil chamber 50 can drain.
- the radial play of the radial extensions 110 and 210 of the valve member 10 in the bore 5 or of the valve piston 12 in the bore 5 is of different sizes: the second radial expansion 210 has very little play in order to guide the valve member 10 in precisely to ensure the bore 5 near the valve seat 32. Accordingly, the play of the first radial enlargement 110 in the bore 5 is made significantly larger in order to prevent the valve member 10 from seizing or to increase friction. It should be ensured that the annular gap 20 formed between the bore 5 and the first radial enlargement 110 still throttles so much that there is no significant fuel flow from the pressure chamber 23 into the intermediate space 15 during the opening phase of the valve member 10. The actual high-pressure sealing and throttling of the fuel flow from the pressure chamber 23 into the spring chamber 28 takes place due to the very small annular gap between the valve piston 12 and the bore 5 due to the small play.
- the operation of the fuel injector is as follows: Via the high-pressure fuel system, not shown in the drawing, fuel is introduced under high pressure into the high-pressure connection 40, so that a predetermined fuel pressure level is maintained in the inlet channel 21 and in the pressure chamber 23 during the entire operation of the fuel injector , When the fuel injection valve is closed, the control element 48 closes the Outlet throttle 46, so that the same fuel pressure prevails in the control chamber 42 as in the inlet channel 21. Since the annular gap 20 between the first radial extension 110 of the valve member 10 and the bore 5 is relatively large, at least approximately the same fuel prevails in the intermediate space 15 pressure as in the pressure chamber 23.
- the diameter of the piston rod 8 is larger than the diameter of the valve piston 12, so that the hydraulic force on the end of the piston rod 8 facing away from the combustion chamber and the force of the spring 27 outweigh the hydraulic force on the pressure shoulder 13 of the valve member 10 ,
- the valve piston 12 with the molded part 14 is pressed against the end face 17 of the valve member 10 facing away from the combustion chamber, and the valve member 10 with the valve sealing surface 30 is thus pressed against the valve seat 32.
- the flow restrictor 46 is opened by the control element 48. Fuel flows from the control chamber 42 into the leakage oil chamber 50 via the outlet throttle 46, and the pressure in the control chamber 42 decreases because the flow resistance of the inlet throttle 44 is greater than the flow resistance of the outlet throttle 46.
- the pressure drop in the control chamber 42 reduces the hydraulic pressure accordingly Force on the end of the piston rod 8 facing away from the combustion chamber, and the piston rod 8 is pressed away from the combustion chamber via the valve piston 12 due to the fuel pressure in the intermediate space 15. Due to the movements of the valve piston 12 away from the combustion chamber, the fuel pressure in the intermediate space 15 immediately drops sharply, as a result of which the valve member 10 also moves away from the combustion chamber due to the hydraulic force on the pressure shoulder 13 and at least on parts of the valve sealing surface 30. In this way, the valve member 10, the valve piston 12 and the piston rod 8 move away from the combustion chamber until the piston rod 8 comes to rest on the end of the guide bore 11 facing away from the combustion chamber.
- the injection process is ended by the control element 48 closing the flow restrictor 46.
- fuel flows again through the inlet throttle 44 into the control chamber 42, and the fuel pressure in the control chamber 42 increases until it corresponds to the fuel pressure in the inlet channel 21.
- the hydraulic force on the end face of the piston rod 8 facing away from the combustion chamber increases, and the piston rod 8 is moved towards the combustion chamber on account of its larger diameter in comparison to the valve member 10, until the valve member 10 with the valve sealing surface 30 comes into contact with the valve seat 32 and which closes at least one injection opening 34.
- the spring 27 plays only a subordinate role in the injection process of the fuel injection valve and mainly serves to keep the fuel injection valve closed when the internal combustion engine is switched off and thus in the depressurized state in the inlet channel 21.
- the recesses 25 on the second radial extension 210 of the valve member 10 are not designed as oblique grooves, but as grooves running parallel to the longitudinal axis 36 of the valve member 10.
- the bore 5 may also be advantageous to design the bore 5 to be stepped in diameter, so that the section of the bore 5 facing away from the combustion chamber viewed from the pressure chamber 23 has a larger diameter than the section facing the combustion chamber viewed from the pressure chamber 23.
- the radial extensions 110, 210 of the valve member 10 have correspondingly different diameters, so that the different clearances of the radial extensions 110, 210 described above remain the same.
- valve piston 12 It is also possible not to generate the closing force on the valve piston 12 by the hydraulic force in a control chamber, but by another, for example magnetically controlled device.
- the closing force generated by this device on the valve piston 12 must be able to exert a greater force than the hydraulic force acting in the axial direction on the pressure shoulder 13 and the valve sealing surface 30 on the valve member 10.
- the fuel injection valve described above is provided for a fuel injection system based on the so-called common rail principle, in which high pressure is constantly maintained by a high-pressure fuel pump in a fuel accumulator, the so-called rail, which is present in the inlet channel 21 and in the pressure chamber 23 during the entire operation ,
- the present injection valve according to the invention can also be used with valve holding bodies in which the closing force on the valve member 10 is generated by one or more closing springs and the injection takes place by controlling the fuel pressure in the pressure chamber 23.
- the pressure chamber 23 there is a low fuel pressure between the injections. Due to the relatively large Annular gap 20, the space 15 is also relieved and depressurized.
- fuel is injected into the pressure chamber 23, so that the pressure rises there.
- valve member 10 lifts off with its valve sealing surface from the valve seat 32 and releases the injection openings 34.
- the annular gap 20 throttles the fuel flow from the pressure chamber 23 into the intermediate space 15 to such an extent that no significant fuel flow into the intermediate space 15 can take place during the opening phase of the valve member 10.
- the end of the injection is initiated in that no more fuel is fed into the pressure chamber 23 and this is relieved.
- the valve member 10 moves towards the combustion chamber by the force of the closing spring until it rests with the valve sealing surface 30 on the valve seat 32.
- the entire opening phase of the valve member 10 is only a small part of the total duration of an injection cycle. During the closing phase of the fuel injection valve, there is therefore a sufficient period of time in which the small amount of fuel that has entered the intermediate space 15 during the opening phase can flow away either into the pressure chamber 23 or past the valve piston 12 into the leakage oil chamber 50.
