Definitions
- the invention is based on a fuel injection valve for internal combustion engines according to the preamble of claim 1.
- a fuel injector known from the patent DE 41 01 235 C, has two closing springs which are arranged in a spring chamber formed in the valve holding body and which counteract the force of the fuel pressure on the valve member.
- the first closing spring is clamped between the end of the spring chamber facing away from the combustion chamber and a spring plate connected to the valve member via a push rod.
- the second closing spring is supported on a stop sleeve that can be connected to the valve member, while the end facing away from the combustion chamber comes to rest on an adjusting bolt.
- thinnings are formed in the wall of the spring chamber, which are caulked inward to fix the adjusting bolt.
- the procedure for assembling the fuel injector is as follows: the first closing spring is inserted into the spring chamber and the spring plate on which the closing spring is supported, facing the combustion chamber.
- the opening pressure of the first closing spring can be adjusted via the length of the push rod and the thickness of the shim the opening pressure of the second closing spring.
- the adjusting bolt is inserted and caulked at the intended location.
- the push rod is pushed through the adjusting bolt to the spring plate and the second closing spring, the shim and the stop sleeve are arranged.
- the valve base body is clamped against the valve holding body with the clamping nut, the valve member coming into contact with the push rod.
- the opening pressure of the two closing springs is measured on the fully assembled fuel injector. If the opening pressure does not match the specifications, the valve body is loosened from the valve holding body again and the shim and the push rod are exchanged according to the measurement result. The fuel injection valve is then reassembled and the opening pressures are measured again. This procedure is repeated until the opening pressures meet the specifications.
- At least two inward-facing caulking holes are formed at the level of the adjusting bolt.
- At least one circumferential rib is formed on the lateral surface of the adjusting bolt, which rib can be pressed into the remaining wall between the bottom of the caulking hole and the spring chamber, in order to achieve better fixation of the adjusting bolt.
- the adjustment bore through which the adjustment tool is inserted into the spring chamber is formed perpendicular to the axis of the valve member, which can be implemented in a technically simple and inexpensive manner.
- the setting tool has a beveled shape at the end of the part which is inserted into the setting hole, as a result of which the setting tool slides on the corresponding advantageously designed bevel on the side of the setting tool facing away from the combustion chamber when it moves into the setting hole.
- the adjustment bore is inclined at an angle of preferably 45 degrees to the axis of the valve member, which makes it possible to exert high axial forces on the adjustment bolt.
- the end of the adjusting tool is advantageously rounded, which allows the adjusting tool to slide on the adjusting bolt when the adjusting bolt is moved in the spring chamber.
- the end face of the adjusting bolt facing away from the combustion chamber is convexly curved outwards. As a result, a bevel is formed on the adjusting bolt, on which the adjusting tool can engage advantageously in the axial displacement of the adjusting bolt.
- a method for producing a fuel injection valve is also advantageous, in which the adjusting bolt is inserted into the spring chamber and the remaining parts of the fuel injection valve are fully assembled.
- the adjusting bolt can be displaced in the spring chamber in a simple manner and the opening pressure can be set permanently without parts of the fuel injection valve having to be replaced or the fuel injection valve having to be disassembled and reassembled.
- FIG. 1 shows a section through Fuel injection valve with two closing springs
- FIG. 2 shows an enlarged section of FIG. 1 in the area of the intermediate disk
- FIG. 3 shows an enlarged section of FIG. 1 in the area of the adjusting bolt of the first closing spring
- FIG. 4 shows the same section as FIG. 3 with an alternative embodiment of the adjusting hole and the Adjustment tool.
- FIG. 1 shows an inventive fuel injection valve for internal combustion engines in longitudinal section.
- the fuel injection valve has a valve holding body 1, against which a valve base body 2 is clamped with a clamping nut 3 with the interposition of an intermediate disk 5.
- a bore 21 is formed in the valve body 2, in which a piston-shaped, axially movable valve member 12 is arranged, which is guided in the section of the bore 21 facing away from the combustion chamber.
- a pressure shoulder 10 is formed on the valve member 12, which is arranged in a pressure chamber 7 surrounding the pressure shoulder 10.
- the pressure chamber 7 can be connected to a high-pressure fuel source, not shown in the drawing, via an inlet channel 4 formed in the valve base body 2, the intermediate disk 5 and the valve holding body 1.
- the end of the valve member 12 on the combustion chamber side is designed as a valve sealing surface 14 which interacts with a valve seat 17 formed in the valve body 2.
- At least one injection channel 19 is arranged in the valve seat 17, which is closed by the valve sealing surface 14 in the closed position of the valve member 12 and in the open position of the valve member 12 via an annular channel 16 formed between the valve member 12 and the bore 21 with the pressure room 7 is connectable.
- a pressure rod 37 which is acted upon by a first closing spring 27, comes to rest, which is arranged largely coaxially with the longitudinal axis 13 of the valve member 12 and which extends into a spring chamber 30 formed in the valve holding body 1.
- FIG. 2 shows an enlarged section of FIG. 1 in the area of the intermediate disk 5.
- the push rod 37 is made smaller in diameter than the guided section of the valve member 12, so that an annular shoulder 11 is formed at the transition of the valve member 12 to the push rod 37.
- the annular shoulder 11 of the valve member 12 comes to rest against a stop sleeve 8 which surrounds the push rod 37 and is guided in the intermediate disk 5.
- the stop sleeve 8 which can be constructed in several parts, protrudes into the spring chamber 30, its end facing away from the combustion chamber being designed as a spring plate against which one end of a second closing spring 28 comes to rest, by means of which the valve member 12 can be brought into the closed position.
- a stop shoulder 25 is formed by reducing the cross section, with which the stop sleeve 8 comes to rest on a stop surface 26 formed in the intermediate disk 5 during its stroke movement.
- the maximum opening stroke of the valve member 12 is thereby limited.
- the stop sleeve 8 comes into contact with its end face 23 under the action of the closing spring 28 on the end face 22 of the valve body 2.
- a piston-shaped first adjusting bolt 31 is arranged near the end of the spring chamber 30 facing away from the combustion chamber, and a piston-shaped second adjusting bolt 32 approximately in the middle between the two ends of the spring chamber 30.
- the second adjusting bolt 32 has a central bore which serves as a guide for the push rod 37.
- the adjusting bolts 31, 32 are fixed in the spring chamber 30 by caulking. Between the First adjusting bolt 31 and a spring plate 24 arranged on the end of the push rod 37 facing away from the combustion chamber, the first closing spring 27, which is preferably designed as a helical compression spring, is arranged under prestress. Correspondingly, between the second adjusting bolt 32 and the spring plate formed on the stop sleeve 8, the second closing spring 28, which is preferably designed as a helical compression spring, is arranged under prestress.
- the spring chamber 30 is connected to a drain line, not shown in the drawing, via a leak oil channel 36 formed in the valve holding body 1.
- One or more circumferential ring webs are formed on the outer circumferential surface of the adjusting bolts 31, 32, into which the remaining wall 46, which remains between the bottom of the caulking bore 43 and the spring chamber 30, is pressed.
- an adjusting bore 52 designed as a through bore is formed in each case.
- FIG. 3 shows a detail from FIG. 1 in the area of the first adjusting bolt 31.
- the side of the adjusting bolt 31 facing away from the combustion chamber is conical, as a result of which a bevel 33 is formed.
- a bore 55 is formed in the center of the axis of the adjusting bolt 31, through which leakage oil can flow from the spring chamber 30 into the drain line 36.
- the adjustment bore 52 is formed in the radial direction towards the center of the valve holding body 1 and approximately forms a right angle with the axis of the adjustment bolt 31.
- An adjustment tool 49 can be inserted through the adjustment bore 52, the part of the adjustment tool 49, which is inserted into the adjustment bore 52, is approximately rod-shaped and is chamfered at the end.
- the setting tool 49 Due to the movement of the setting tool 49 into the spring space, the setting tool comes to bear on the bevel 33 of the setting bolt 31. As a result of the further movement of the setting tool 49, the bevel of the setting tool 49 slides on the bevel 33, which results in an axial force on the setting pin 31 which pushes the setting pin 31 towards the combustion chamber.
- FIG. 4 shows an alternative embodiment of the adjustment bore 52, which here has an angle between 30 and 60 degrees, preferably 45 degrees to the axis of the adjustment bolt
- the part of the setting tool 49 which is inserted into the setting hole 52 is rounded at its end and comes to bear on the bevel 33.
- the adjusting bolt 31 is moved towards the combustion chamber in the axial direction.
- the setting tool 49 slides on the bevel 33.
- the adjustment is made via the adjustment bore or adjustment bores 52 in the second adjustment bolt 32.
- the side of the adjusting bolt 31 facing away from the combustion chamber is not conical, but convexly curved in another form.
- the 32 can also several adjustment bores 52 symmetrically the axis of the spring chamber 30 can be arranged around and used for adjustment at the same time.
- the fuel injector works as follows: At the beginning of the injection cycle, fuel is introduced into the pressure chamber 7 under high pressure through the inlet channel 4. This results in a resulting force on the pressure shoulder 10 in the axial direction away from the combustion chamber, since the valve member 12 is pressed by the first closing spring 27 via the push rod 37 with the valve sealing surface 14 onto the valve seat 17, the fuel injection valve opens only when the fuel pressure in the Pressure chamber 7 has reached the opening pressure and the force on the pressure shoulder 10 is greater than the force of the first closing spring 27. By lifting the valve sealing surface 14 from the valve seat 17, the injection channel 19 is connected to the pressure chamber 7 via the ring channel 16 and fuel is injected into the Injected combustion chamber.
- the valve member 12 After the stop of the valve member 12 with the annular shoulder 11 on the stop sleeve 8, the valve member 12 therefore remains in this position until a correspondingly higher fuel pressure has built up in the pressure chamber 7 due to the fuel that has been added, which fuel pressure is able to pass through the resulting force the annular shoulder 10 to counteract the force of both closing springs 27, 28.
- the stop sleeve 8 comes with its impact shoulder 25 on the abutment surface 26 and the opening stroke movement is ended.
- the opening stroke movement at the beginning against the closing force of one and after a partial stroke of the force of two closing springs (27, 28) results in a favorable course of the injection, in particular when the fuel injection valve is used in self-igniting internal combustion engines.
- the closing of the fuel injection valve is initiated in that the fuel pressure in the pressure chamber 7 drops until the force on the pressure shoulder 10 is no longer sufficient to counteract the force of the closing springs 27, 28.
- the valve member 12 is accelerated via the stop sleeve 8 and the push rod 37 in the direction of the valve seat 17 until the valve member 12 with the valve sealing surface 14 comes into contact again with the valve seat 17 and closes the injection channel 19.
- the two adjusting bolts 31 and 32 are arranged, which are axially displaceable in the spring chamber 30.
- the remaining parts are arranged in the spring chamber 30 and the valve base body 2 is braced against the valve holding body 1 with the clamping nut 3 with the interposed washer 5.
- An adjustment tool 49 is inserted through the adjustment hole 52 of the first adjustment bolt 31 and the first adjustment bolt 31 is moved into a position counter to the force of the first closing spring 27.
- the opening pressure caused by the first closing spring 27 is then measured, whereupon the position of the adjusting bolt 21 or the adjusted opening pressure can be corrected by moving the first adjusting bolt 21 in its axial position according to the measurement result by means of the adjusting tool 49. Is the measured opening pressure of the fuel injection valve tils too large, the adjusting bolt 31 must be moved away from the combustion chamber, it is too small, accordingly towards the combustion chamber. This procedure is repeated until the desired opening pressure has been set on the fuel injector.
- the opening pressure is measured continuously by means of a suitable device when the adjusting bolt 31 is moved.
- the adjusting bolt 31 is then caulked in the manner described above by pressing in the remaining wall 46 of the caulking hole 43 in the spring chamber 30.
- the setting tool 49 is removed from the setting hole 52 and the setting hole 52 is closed. This can be done, for example, by pressing a steel ball into the setting bore 52. The same procedure is now followed when positioning the second adjusting bolt 32.
- the tool has a cam-like formation at its end inserted into the spring chamber having . The force on the adjustment bolt is then generated by turning the adjustment tool.
- Way can be adjusted by moving an adjusting bolt.
