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 injection valve is considered in which the armature is decoupled from the valve needle.
  • the armature should quickly release from the valve stop located on the lower stop (second stop), quickly overcome the Ankerokweg and open the valve quickly when hitting the top stop (first stop). If the energization of the valve is terminated, the valve needle closes again. The armature, after the valve needle closes the valve seat, continues to move until it encounters the lower limit stop.
  • the anchor From the bottom stop, the anchor rebounds 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.
  • the medium to be injected is squeezed, so that when closing the armature is damped and quickly returned to the rest position.
  • 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.
  • DE19849210A1 shows a known injection valve.
  • the injector according to the invention with the features of claim 1 makes it possible to better dampen the armature and thus reset the armature after closing the injector faster than before in its rest position. At the same time, the damping is reduced according to the invention when opening the injection valve, so that the injection valve opens faster.
  • the armature dissolves faster than before from the valve needle, whereby the dynamics of the valve is increased and thus the function is improved.
  • 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.
  • an injection valve according to the invention comprising a housing with at least one injection opening on an outlet side, a magnetic coil and a magnet armature linearly movable by the magnetic coil. Furthermore, the injection valve has a valve needle. This valve needle is used to open and close the at least one injection opening. The valve needle extends along a longitudinal axis and is linearly movable.
  • the magnet armature In the magnet armature, a through hole is formed.
  • 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 two-mass system.
  • 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.
  • the stop surface is inclined before and after the contact of stop element and counter element to the counter element.
  • the stop element is elastically deformed, so that the space between stop surface and counter surface decreases. Due to the elastic design of the stop element according to the invention, it is possible that the nip and the throttle flow between stop surface and mating surface to move when moving together and Vonfactwegbe admire from stop surface and mating surface. As a result, the damping during opening and closing of the injection valve can be set very precisely.
  • the stop element is firmly connected to the valve needle. Accordingly, then the counter element is located on the armature.
  • the counter element is an integral part of the magnet armature.
  • the counter surface is the side of the magnet armature facing the abutment surface. 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 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 defined on the opposite surface facing the stop surface. This means that the angle of less than 90 ° defines that the stop surface is inclined towards the opposite surface. It is sufficient if the stop surface only in places has this inclination with the appropriate angle. During the abutment of the counter surface on the stop surface, 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.
  • the angle without the contact of abutment surface and mating surface is a maximum of 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.
  • the angle is elastically deformed by at least 0.01 °, preferably at least 0.15 °, by the abutment of counter surface and abutment surface.
  • 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.
  • the stop surface is an annular surface around the valve needle.
  • the inner portion is an inner annular surface.
  • the outer portion is a further annular surface located outside the inner portion. The angle without the contact of abutment surface and counter surface is greater at the outer portion than at the inner portion.
  • 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.
  • outer surface a side facing away from the opposite surface.
  • 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.
