Definitions
- the present invention relates to an injection valve for injecting a medium, in particular for injecting fuel into a combustion chamber.
- the injection process can be designed as a channel or direct injection.
- valves for the injection of gasoline with a valve needle which is moved by an actuator, such as an electromagnet or piezo actuator, against a closing spring so that a desired amount of fuel is introduced directly targeted into the combustion chamber.
- an actuator such as an electromagnet or piezo actuator
- an injection valve in which the armature is decoupled from the valve needle.
- the armature When opening the injector, the armature should quickly release from the located on the valve needle lower stop (second stop), overcome the Ankerokweg quickly and at
- Stop rebounds the anchor several times until it reaches its rest position again.
- the time it takes for the armature to return to the rest position is critical to the ability of the valve to rapidly eject successive injections with high accuracy.
- a crimp gap is formed at the lower stop, that is to say between magnet armature and the corresponding stop sleeve on the valve needle. In this nip the medium to be injected is squeezed, so that when closing the
- the nip prevents rapid opening by stopping the movement dampens when opening.
- the nip must therefore be designed as a compromise so that the armature opens the valve sufficiently quickly, and is reset sufficiently quickly to the rest position. Disclosure of the invention
- the injector according to the invention with the features of claim 1 makes it possible to better dampen the armature and thus the armature after closing the injector faster than before in his
- Valve needle which increases the dynamics of the valve and thus improves the function.
- the force required to open is reduced, which reduces the power consumption of the injector and thus the total energy consumption of the vehicle. As a result, the consumption of the vehicle decreases.
- closing the injection valve the following advantages result: The movement of the armature is attenuated more than previously. As a result, the magnet armature reaches its rest position earlier than previously, resulting in short successive ones
- Valve needle is created. All these benefits are achieved through a
- Injection valve comprising a housing with at least one injection opening on an outlet side, a magnetic coil and a magnetic armature linearly movable by the magnetic coil. Furthermore, the
- Injection valve on a valve needle. This valve needle is used for opening and
- the valve needle extends along a longitudinal axis and is linearly movable.
- a through hole is formed in the magnet armature.
- the valve needle is in this through hole.
- the armature is linearly movable between a first and a second stop relative to the valve needle. This creates a
- the first stop is on a side facing away from the outlet formed of the armature.
- the first stop is formed by a ring on the valve needle.
- the second stop is formed on an outlet-facing side of the magnet armature.
- the second stop is formed by a stop element and a counter element. At the second stop, the stop element and the counter element hit each other.
- the stop element on a stop surface. On the counter element one of the stop surface opposite counter surface is formed. The stop surface and the counter surface meet each other at the second stop.
- the stop element is designed to be elastic, so that an angle between the longitudinal axis and stop surface changes when striking counter surface and stop surface. In particular, it is provided that the stop surface before and after the contact of stop element and
- stop element is firmly connected to the valve needle. Accordingly, then the counter element is located on
- the counter element is in particular an integral part of the magnet armature.
- the counter surface is the
- Stop surface facing side of the armature it is possible that the stop element is firmly connected to the armature.
- the counter element is then firmly attached to the valve needle. It is crucial that at least one of the two opposing surfaces is formed elastically on the second stop. This at least one elastic surface is referred to in the present application as a stop surface.
- the stop element or counter element is integrated in the valve needle.
- the angle between the longitudinal axis and abutment surface is at least in places smaller than 90 ° without contact of abutment surface and counter surface. The angle is on the
- Counter-surface is inclined towards. It is sufficient if the stop surface only in places has this inclination with the appropriate angle.
- the stop surface is deformed, so that the angle is increased.
- the abutment surface is inclined in the direction of the mating surface, so that a relatively large, filled with the medium space between abutment surface and mating surface is present.
- the movement is first damped by a throttle flow and as soon as the stop surface and counter surface meet, the stop surface is deformed, so that the stop surface is aligned parallel to the counter surface. This creates a nip for damping the movement of the magnet armature.
- the Damping effect thus increases with the decreasing distance between the stop surface and counter surface.
- Stop surface and counter surface not more than 89.99 °, preferably a maximum of 89.85 °. As already described above, this angle does not have to be present over the entire stop surface.
- Counter surface and stop surface of the angle by at least 0.01 °, preferably at least 0.15 °, is elastically deformed.
- the stop surface is deformed so far until stop surface and counter surface are aligned parallel to each other.
- the stop surface is divided into an inner portion and an outer portion.
- the inner portion is closer to the longitudinal axis than the outer portion. Particularly preferred is the
- Stop surface an annular surface around the valve needle around.
- the inner portion is an inner annular surface.
- the outer section is an outside of the
- Inner section lying further annular surface. The angle without the contact of abutment surface and mating surface is greater at the outer portion than on
- the stop surface tends towards the counter surface with increasing distance from the longitudinal axis.
- the inner portion is formed without the contact of the stop surface and counter surface parallel to the counter surface.
- the inner portion may be slightly inclined to the opposite surface or concave.
- On the stop element is a side facing away from the opposite surface than
- This outer surface should also be shaped accordingly, so that sufficient elasticity for deformation of the stop surface is given. Therefore, the outer surface is preferably inclined towards the counter element or at least locally concave. Alternatively, the outer surface may be partially parallel to the stop surface. It is also decisive that the stop element is formed as thin as possible, so that the stop surface can deform elastically.
- grooves are preferably provided in the stop element. Particularly preferably, these grooves are formed completely circumferentially about the longitudinal axis.
- the first stop is preferably formed by a paragraph or by a ring on the valve needle.
