Definitions
- the present invention relates to a device for controlling an injector, which can be used for example as a fuel injection valve.
- An injector has a nozzle needle (also known as an injector needle) that allows a high pressure fuel to escape when an injector outlet hole is released.
- This nozzle needle acts in conjunction with this outlet opening like a plug, which in a lifting an escape of the Fuel allows. Accordingly, it is therefore necessary to lift this needle in relatively short time intervals and to let slide back into the outlet opening after a short time.
- hydraulic servo valves are used, which are controlled by solenoid valves. The servo valves are required for the controlled opening and closing of the nozzle needle. This makes it possible to determine the start of injection, the duration of injection and the end of injection.
- so-called servo valves are used instead of the direct control, which control the nozzle needle and are themselves controlled by a solenoid valve.
- a pressure level which acts on the nozzle needle in the closing direction is established in a control space cooperating with the nozzle needle with the aid of the fuel which is available under high pressure.
- This control chamber is typically connected via an inlet throttle to the high-pressure region of the fuel.
- this control chamber has a small closable outlet throttle, from which the fuel can escape. If this is done, the pressure in the control chamber and the closing force acting on the nozzle needle is reduced. This leads to a movement of the nozzle needle, which releases the outlet opening at the injector tip.
- the servo valve includes the inlet throttle, the control chamber as well as the outlet throttle.
- the outlet throttle of the control chamber is optionally closed or opened by means of a solenoid valve or another suitable valve. Due to the controlled opening of this outlet throttle, the pressure in the control room is combined with the inlet throttle of the valve. This pressure is then, as already briefly explained above, responsible for the opening and closing of the nozzle needle.
- a certain spring force is required, which a closure member (in the jargon also: anchor) pressed against the outlet throttle to drain fuel and thereby reducing pressure in to prevent the control chamber from the drain throttle.
- the set spring force with which the closure member is pressed against the sealing point of the outlet throttle must be overcome so that the closure member releases the outlet throttle as quickly as possible.
- Typical required switch-on times that is to say the time from the beginning of the current supply to the closing of the closure member at an upper stroke limit of such solenoid valves, are in the range of approximately 200 microseconds.
- an anchor element closure member
- the device is characterized in that the valve is designed to create a direct connection between the high-pressure side and the control chamber, when the pressure level in the passage space equal to or greater than a predetermined Value is or if a certain ratio of the pressure in the control room to the pressure in the passage space is exceeded.
- valve described herein may be the closer considered in the introductory part of the description servo valve.
- high pressure fluid also flows out of the control space toward the passage space, so that the force acting on the injector component decreases due to the pressure reduction.
- the closure member is then again sealingly connected to the outlet throttle of the passage space, there is an inhibition of the outflow of fuel.
- the fuel With the aid of the first connection, the fuel then flows from the high-pressure region at high pressure into the passage space, so that a pressure rise occurs therein.
- the control chamber is also flooded with the aid of the second compound with the fuel under high pressure, so that the force acting on the injector (eg., Düsennadel) force increases and leads to a closing of the injector.
- the valve of the present invention reacts differently.
- the valve is designed to to create a direct connection between the high pressure area of the fuel and the control room.
- the direct connection between the high-pressure region and the control chamber does not extend beyond the passage space. Rather, the direct connection is thus a coupling of the high pressure fuel to the control room.
- the first connection is provided by means of an inlet throttle, which is a throttled connection from the passage space to the high pressure area of the injector, preferably this connection being independent of a condition of the valve.
- the anchor member is not set to an opening of the passage space, high pressure fluid (such as fuel) escapes in the direction of the low pressure area released by the anchor member, so that also a continuous flow through the inlet throttle of a pressure decrease in the passage space or in the control room can not counteract in such a state.
- high pressure fluid such as fuel
- the valve is further designed to establish the direct connection between the high-pressure region and the control chamber only when the pressure level in the passage space is equal to or greater than a predetermined value, whereas otherwise this connection is closed.
- the direct connection between the high-pressure region of the injector and the control chamber is thus realized by the valve only when a certain pressure level is reached in the passage space. If, due to the connection of the control chamber to the high-pressure region, the pressure level in the control chamber has matched that of the passage space, the valve is optionally designed to close the direct connection again.
- the valve is configured to establish a direct connection between the high pressure side and the control chamber when the pressure level in the passage space is equal to or greater than a predetermined value, this predetermined value being based on a difference in pressures between the Passage space and the control room based.
- a predetermined value being based on a difference in pressures between the Passage space and the control room based.
- the valve establishes the direct connection when the pressure in the passage space is greater than a pressure prevailing in the control space.
- the second connection is a throttled connection and / or the direct connection is an unthrottled connection.
- a throttled connection means that a fluid flowing through such a conduit is inhibited in its flow, so that a pressure equalization over such a throttled connection takes some time.
- an unthrottled connection it is assumed that there are no flow impediments for the fluid in order not to prevent a pressure compensation of the fluid via such a connection.
- the valve is a valve guide, between the other of the two sides of the passage space and the Control chamber is arranged, and comprises a valve insert which is slidably mounted in the valve guide.
- the valve guide has a channel which does not establish a direct fluid connection between the high-pressure region and the control chamber in a first position of the displaceable valve insert in the valve guide and establishes a direct fluid connection between the high-pressure region and the control chamber in a second position of the displaceable valve insert in the valve guide , Accordingly, there is no direct connection between the high-pressure region and the control chamber in the first position of the valve insert.
- a particularly simple implementation of the valve is achieved.
- the valve insert moves at a predetermined pressure level in the passage space at least temporarily in the second position, whereby the two control chambers are separated.
- valve insert to move into the first position when the pressure drops below a predetermined pressure level in the passage space. It can also be provided that the valve insert moves into the first position when a pressure difference between the passage space and the control chamber falls below a predetermined value. Thus, for example, at a higher pressure in the control chamber relative to a pressure level in the passage space, the valve core can be moved into the first position.
- the movement of the valve insert is done automatically by the different applied pressures in the control chamber and the passage space because they exert a certain force on the valve core on the respective side of the valve insert (side in the passage space or side in the control chamber) and this corresponding to the prevailing pressure levels in In connection with the effective pressure surface of the valve insert a shift in one direction can be made.
- this further comprises a stop element which limits the stroke of the valve insert in a movement from the first position to the second position. This makes it possible to make the manufacturing tolerances on the components generous and overall to reduce the cost of the claimed device.
- the stroke of the valve insert limiting stop element causes the advantageous circumstance, after which the return travel of the valve core is reduced to the first position, so that the activation of the valve can be achieved faster in the next injection.
- the stop element is a disk-shaped body which has one or more passage openings.
- stop element attached to the valve guide preferably welded.
- stop element is arranged in the control chamber or is arranged on the side facing the control chamber side of the valve guide.
- the optional provision of at least one passage opening in the stop element serves to flow through the fuel toward the control chamber or to the second connection.
- the device further comprises a return element, which acts on the valve core with a force urging it from the second layer to the first layer.
- a return element acts on the valve core with a force urging it from the second layer to the first layer.
- the restoring element is an elastic element, preferably a spring or a spiral spring, which urges the valve core with a certain force in the first layer.
- the elastic element is arranged on a side facing the control chamber side of the valve core.
- the valve is a 3/2-way valve, since it has over the 2/2-way valves used in the prior art, an additional fuel passage in the high pressure region of the injector, which has a direct fluid connection in a certain state of the valve with the control chamber.

- FIG. 6 several plan views of a variety of possible
- Fig. 7 shows several variants of a stop element for limiting the
- FIG. 1 shows a partial sectional view of a schematic representation of an injector 2.
- the movable injector needle 6 can be seen, which can be moved in the direction of the valve 7 arranged above it. If the Injektornadel 6 moves toward the valve 7, it comes at the end of the injector, not shown, to a flow of fuel. In the other case, in which the injector needle 6 is arranged at its location remote from the valve 7, no fuel flows out of the injector 2.
- a control chamber 5 In the immediate vicinity of the Injektornadel 6 is located between the valve 7, a control chamber 5, in which a variable pressure can be generated.
- the valve 7 with its passage opening 3 connects directly to the closure member or the anchor element 4, which can close the passage opening 3 fluid-tight.
- a certain pressure is required, which urges the anchor element 4 in the direction of the passage opening 3. This is achieved by means of the spring interacting with the anchor element 4. If you now want to lift the anchor element 4 from the through hole 3, so that there is a pressure change in the through hole 3 and the control chamber 5, so with the aid of an electromagnet, the armature element 4 of the passage opening 3 wegssende force generated.
- a magnetic inner pole 23 and a Magnet outer pole 22 provided in the injector 21, which together with a coil form an electromagnet for driving the closure member.
- FIG. 2 shows an enlarged view of the device 1 according to the invention, in particular of the valve 7. It now only recognizes the lower portion of the anchor member 4, which closes in a direction acting in the direction of the valve a passage space 3 tight, whereas in an attracted state of the Anchor member 4 of the passage space 3 has a fluid connection with the surrounding the anchor member 4 area.
- the sealing seat 41 ensures a tight connection.
- a passage opening 32 is therefore closed by means of the anchor element 4.
- the passage space 3 also has an inlet throttle 8, which allows a fuel under high pressure to flow into the passage space 3.
- a second throttle 9, which is referred to as outlet throttle 9, which allows a fluid connection to the control chamber 5.
- the valve insert 72 is arranged movable relative to the valve guide 71. In the case of a concern of certain pressures in the control chamber 5 and the passage space 3, therefore, the valve core 72 can be moved toward or away in the direction of the passage opening 3.
- FIG. 3a shows the state in which the pilot valve, that is to say the opening of the anchor element 4 with respect to the passage opening 3, in a closed state and accordingly the injector 2, does not inject fuel.
- the passage opening is provided in a so-called seat plate 31.
- the armature member 4 separates the high pressure area HP from the low pressure area of a fuel.
- FIG. 3 b shows a state in which the pilot valve is open and injection is performed by the injector 2.
- Opening the pilot valve means raising the anchor member 4 so that fuel can flow from the high pressure area HP to the low pressure area LP from the passage space 3. Accordingly, raising the anchor element 4 allows a direct fluid connection between the passage space 3 and the area surrounding the anchor element 4. Accordingly, there is an outflow of fuel from the passage space 3 in the direction of the anchor element 4. This also means that the fuel in the control chamber 5 under high pressure flows through the discharge throttle 9 to the low pressure region of the injector due to the existing pressure difference. This leads to a pressure reduction above the Injektornadel 6, whereby the resulting Reduction of the pressure on the Injektornadel stresses 6 leads to a lifting of the Injektornadel 6 from its nozzle seat and an injection takes place.
- the inlet throttle 8 and the outlet throttle 9 and the passage space 3 are dimensioned so that the operations described take place.
- Fig. 3c shows the state in which the pilot valve is closing and an injection of the injector 2 is still present.
- 3d shows a state in which the pilot valve is closed, the injector needle 6 closes and the injection of the injector 2 is ended.
- FIG. 3 d also shows a sectional view of the device shown in FIGS. 3a-3c discussed section, but in Fig. 3d shows a different sectional plane in order to better illustrate the features of the invention can.
- the anchor element 4 has just been brought into a sealing position with respect to the opening of the passage space 3, so that now a fuel under high pressure flows into the passage space 3 via the inlet throttle 8.
- the pressure level in the passage space 3 increases, so that due to the very high pressure in the passage space 3 with respect to the control chamber 5, a movement of the valve core 72 away from the passage space 3 is generated.
- Figure 4 is a sectional view of another embodiment of the present invention.
- valve insert 72 which serves to reset the valve core 72 after injection back to the starting position.
- the valve insert 72 will not remain in a position in which there is a fluid connection through the channel 10 provided in the valve guide, but will be returned to its starting position with the aid of the spring 13 , This has the advantage that the valve core 72 does not respond to the activation of the next injection first has to overcome the valve lift and thereby shorten the reaction time of the injector.
- Fig. 5 shows a further embodiment of the present invention, in which a stop element 1 1 is provided in the form of a disc-shaped body to limit the stroke of the valve core 72.
- the stop element 1 1 is attached by means of laser welding to the valve guide 71.
- the manufacturing tolerances on the components can be made generous.
- the stop element 1 1 through openings 12, which serve to flow fuel through the stop element 1 1.
- FIG. 6 shows four different embodiments of the outer shape of the valve guide 71. If these are then inserted into a bore which is flush with the circular outer sections of the valve guide 71, the flattened sections can serve to guide fuel past the sleeve laterally.
- each of the two stop elements 1 1 has at least one through hole 12.
- the function of two components is combined in one component.
- the blank of the valve 7 is preferably designed as MIM (Metal Injection Molding) and already has all holes except for the outlet throttle 9 and the inlet throttle 8, which are subsequently eroded.
- a metal injection molding process is a manufacturing process in which a green body is injection molded and then finish sintered in a furnace. This can be very Cost-effective implementation of complex component geometries and cutting of the component to a minimum.
