Definitions
- the invention relates to a control valve for a fuel injector, which can be used for the injection of fuel under high pressure in the combustion chamber of an internal combustion engine.
- a fuel injector is known from the prior art, for example, as it can be used for the injection of fuel into the combustion chamber, preferably by high-speed, self-igniting internal combustion engines.
- the fuel injector is supplied with fuel under high pressure by means of a high-pressure pump and has a valve needle which alternately releases or closes one or more injection openings as a result of its longitudinal movement.
- the fuel can be injected into the combustion chamber at a precisely determined time of the power stroke of the internal combustion engine, which takes place at very high pressure in order to achieve good atomization of the fuel.
- the movement of the valve needle is achieved on the one hand by the hydraulic pressure of the fuel, which acts on the valve needle in the opening direction.
- the opposite is a closing force, which is generated by the fuel pressure in a control room.
- the fuel pressure in the control chamber is adjusted via a control valve.
- the control valve known from DE 10 2006 021 741 A1 has a control sleeve, which is connected to a magnet armature and by the energizing or Non-energizing the electromagnet is moved in its longitudinal direction.
- the control sleeve is seated on a valve seat which limits a pressure chamber connected to the control chamber radially outward, wherein when the control sleeve lifts from the valve seat, the pressure chamber and thus the control chamber is connected to a leakage oil chamber, while sitting on the control sleeve on the Valve seat of the pressure chamber and thus the control room is separated from the leakage oil space.
- the control sleeve has on its end facing the valve seat on a sealing surface, which is formed substantially annularly circular. It can also be provided that a slightly conical shape of the sealing surface is provided in order to obtain a line contact. This increases the sealing effect, so that even with a relatively small spring force with which the valve sleeve is pressed onto the valve seat, a good seal is achieved.
- the injection pressure with which the fuel is introduced into the injector by the high-pressure pump is up to 1800 bar in modern high-pressure injection systems, such as those used for self-igniting high-speed internal combustion engines, and will continue to increase in the future.
- This high fuel pressure is also in the control chamber and thus in the pressure chamber and there leads to the control sleeve is radially expanded. Since the pressure drops when the control valve is open and rises again when the control valve is closed, this occurs
- the control valve according to the invention for a fuel injector has the advantage that the wear in the region of the valve seat is markedly reduced compared to the known valve, so that a reliable function over the entire service life of the control valve is ensured.
- a recess is formed on the side of the valve body, on which the valve seat is located, which is in hydraulic communication with the pressure chamber. Varying pressure in the pressure chamber, so on the one hand, the control sleeve, but also the recess in the valve body is radially expanded, wherein the recess is such that the relative movement of the valve seat and the sealing surface is at least approximately equal, which significantly reduces wear in this area ,
- the control sleeve is guided on a guide pin, which protrudes from the side facing away from the valve body side of the guide sleeve into the guide sleeve.
- the guide sleeve is guided independently of the valve body, so that an accurate alignment of the valve sleeve on the valve seat is possible.
- the guide pin has an extension which projects into the recess of the valve body. As a result, the volume of the pressure chamber can be reduced, which increases the dynamics of the control valve, since the pressure changes in the pressure chamber and thus in the control room can be made faster. In this case, the function of the recess in the valve body is maintained.
- valve seat is conical, thus has the shape of a truncated cone, wherein the valve seat is formed around the recess around.
- the inner diameter of the guide sleeve and the diameter of the recess have the same diameter on.
- control valve in a fuel injector for internal combustion engines, in which the fuel pressure is adjusted in a control chamber by the control valve. Due to the changing pressure in the control chamber, a valve needle can be moved in its longitudinal direction, which controls the fuel injection of the fuel injector into a combustion chamber of the internal combustion engine.
- FIG. 2 is an enlarged view of the control valve in the region of the valve seat or the sealing surface
- FIG. 3 shows another embodiment of the control valve, wherein the same
- FIG. 5 shows a fourth exemplary embodiment in which the guide pin projects far into the valve body.
- Description of the embodiments 1 shows a longitudinal section through a fuel injector, in which a control valve according to the invention is used.
- the fuel injector has a housing 1, in which a control valve 3 is formed, which controls the movement of a valve needle 10.
- the valve needle 10 is in this case in the form of a piston and, with its end facing away from the control valve 3, controls an injection opening through which fuel can be injected into a combustion chamber of an internal combustion engine.
- the valve needle 10 is guided in this case in a valve body 5, which is arranged in the housing 1 and which has a bore 12 in which the valve needle 10 is guided.
- a control chamber 7 is limited, the fuel pressure acts on the control valve side facing the valve needle 10 and so generates a closing force on the valve needle 10.
- the control chamber 7 is always supplied with fuel under high pressure. This is done via an annular space 14 which surrounds the valve body 5 and which is connected via a bore, not shown in the drawing, to a fuel port, via which fuel compressed by a high-pressure pump is supplied.
- the annular space 14 is connected through a throttle bore 15 with the control chamber 7, so that with a certain time delay always the same fuel pressure, both in the control chamber 7, as well as in the annular space 14 prevails.
- the annular space 14 is sealed off via a seal 17 with respect to the low-pressure region of the fuel injector.
- the pressure in the control chamber 7 is regulated by the control valve 3.
- the valve body 5 has a flow channel 20, which runs centrally and coaxially with the valve needle 10.
- a throttle 22 is formed, so that the amount of the outflowing fuel can flow only throttled through the drain passage 20.
- the outlet channel 20 opens into a recess 24, which is part of a pressure chamber 26, wherein the pressure chamber 26 is limited by a control sleeve 25, a guide pin 30 and through the recess 24 of the valve body 5.
- the control sleeve 25 is slidably guided on the guide pin 30 and connected to a magnet armature 34, which can be moved by an electromagnet 35.
- a closing spring 32 is supported between the control sleeve 25 and an annular disc 29, which is firmly connected to the guide pin.
- the electromagnet 35 is energized and the control sleeve 35 pulled by the armature 34 upwards, d. H. away from the valve seat 28.
- the pressure chamber 26 is connected to the leakage oil chamber 38, which is depressurized, since it is connected via a drain 40 with a low pressure system.
- the pressure in the pressure chamber 26 and in the control chamber 7 decreases then and the closing force on the valve needle 10 decreases so far that the valve needle 10 moves in the direction of the control chamber 7 and thereby releases injection ports through which fuel is now injected, for example, into a combustion chamber.
- a sealing surface 27 is formed, which is formed substantially annularly circular and which rests on a valve body 5 formed on the flat valve seat 28.
- the control sleeve 25 is pressed with sufficient surface pressure against the valve seat 28, so that the pressure chamber 26 is sealed against the pressureless leakage oil chamber 38.
- the valve body 5 has in the region of the valve seat 28 through the recess 24 has a substantially hollow cylindrical shape.
- the recess 24 is dimensioned such that due to the pressure in the pressure chamber 26, a widening of the valve body 5 in the region of the recess 24 takes place radially outward, just as the control sleeve 25 is radially widened by the pressure in the pressure chamber 26.
- FIG. 3 shows a further exemplary embodiment of the control valve 3 according to the invention.
- the valve seat 28 ' is conical here, and accordingly, the sealing surface 27' also has a conical shape.
- the sleeve is always centered relative to the valve seat 28' so that the outflow of the fuel from the pressure chamber 26 occurs symmetrically during the opening movement of the control sleeve 25.
- Figure 4 shows another embodiment, in which case an extension 31 is formed here on the guide pin 30 ', which projects into the recess 24.
- the volume of the pressure chamber 26 can be decisively reduced, which considerably shortens the response time of the control valve 3. The lower the volume in the
- valve seat 28 ' is also conical in this case, however, the conical angle compared to the embodiment of FIG. 3 is significantly increased. By this cone angle ⁇ , the wear between the sealing surface 27 'and the valve seat 28' can be further reduced: In the embodiment of FIG. 3, the sealing surface 27 'slides easily when placed on the conical valve seat 28' to the outside. At the same time, the valve seat 28 'is pressed inwards by the control sleeve 25, so that it turns into a valve for each closing movement of the control sleeve 25
- valve seat 28 'and sealing surface 27' Relative movement between valve seat 28 'and sealing surface 27' comes. If the valve seat 28 ', however, formed as a cone with a large opening angle, this sliding can be prevented when placing the control sleeve, at the same time the relative movement of the valve seat 28' and sealing surface 27 'is suppressed by the fluctuating pressure in the pressure chamber 26.
- cone angle ⁇ for the valve seat 28 ' so as the opening angle of the corresponding cone, a value of 155 ° to 175 ° has proven to be particularly advantageous, in particular an angle of about 160 °.
- the sealing surface (27 ') has at least approximately the same cone angle as the valve seat 28'.
- FIG. 5 shows a further exemplary embodiment of the control valve.
- a bore is provided here, which extends through the entire valve body 5 and extends into the control chamber 7, the diameter of the bore 12 'corresponding to the inner diameter of the control sleeve 25.
- the guide pin is provided here, which extends through the entire valve body 5 and extends into the control chamber 7, the diameter of the bore 12 'corresponding to the inner diameter of the control sleeve 25.
- valve body 5 is designed such that on the one hand it guides the control sleeve 25 and on the other hand projects far into the valve body 5.
- 5 bevels 33 are formed in the region of the valve body so that a hydraulic connection of the pressure chamber 26 'to the control chamber 7 is ensured is. Since the valve body 5 "in the region of the valve seat 28" exactly the same shape, namely a hollow cylindrical shape as the control sleeve 25, resulting in identical elastic properties, so that a relative movement between the valve seat 28 and sealing surface 27 "by the changing pressure in the pressure chamber 26th 'is excluded.
