Definitions

  • the present invention relates to an injection valve in order to be used in internal combustion engines.
  • the spraying of the fuel into the combustion chamber is realized by means of injection valves.
  • the fuel entering into the injection valve through an inlet channel, is transferred towards the valve region through a control chamber. Afterwards, in the valve region, the fuel is transferred to the combustion chamber in a controlled manner by the valve member.
  • the fuel moves in a vortex manner inside the control chamber, in other words, it is desired that the fuel moves by rotating around the center axis inside said control chamber.
  • the present invention relates to an injection valve, for eliminating the above mentioned disadvantages and for bringing new advantages to the related technical field.
  • the main object of the present invention is to provide an injection valve where the fuel advances by rotating inside the control chamber.
  • the present invention is an injection valve for use in internal combustion engines and having at least one control chamber, at least one center axis extending at the center of said control chamber, and at least one inlet channel in order to provide fuel entry into the control chamber. Accordingly, the present invention is characterized in that the inlet axis of the inlet channel defined in the extension direction of the inlet channel is positioned in a manner not intersecting the center axis.
  • pluralities of inlet channels are provided around the center axis such that equal distance is provided in between.
  • the inlet channel is positioned at different heights.
  • the subject matter injection valve comprises a control chamber (10), and at least one inlet channel (20) providing fuel entry to said control chamber (10).
  • Said control chamber (10) preferably has a circular form.
  • a center axis (a) is defined at the center of the control chamber (10).
  • the center axis (a) is extending in the direction of the height of the control chamber (10).
  • X axis (x) and y axis (y) are defined which separate the control chamber into four regions in an orthogonal manner with respect to the center axis (a).
  • the inlet axis (b) which defines the extension direction of the inlet channel (20).
  • the inlet axis (b) preferably extends in a parallel manner with respect to the x axis (x) or y axis (y).
  • the inlet axis (b) extends in a parallel manner with respect to the x axis (x) or y axis (y) such that a distance remains in between, and the inlet axis (b) extends in an orthogonal manner with respect to the other axis. In other words, the inlet axis (b) does not intersect the center axis (a).
  • two or more inlet channels (20) can be provided. Accordingly, in case there are two inlet channels (20), it is preferred that there is an angle of 180 degrees between the two inlet channels (20) as can be seen in Figure 3a. In alternative embodiments, the number of inlet channels (20) can be further increased as can be seen in Figure 3b. And accordingly, the inlet channels (20) are arranged such that they are preferably at equal distances with respect to each other.
  • the inlet channels (20) can be provided at different heights.
  • the fuel, coming from the inlet channel (20) hits the inner wall of the control chamber (10) at an angle which is smaller than 90 degrees.
  • the fuel enters into the control chamber (10) in a manner close to the tangent of the inner wall.
  • pluralities of inlet channels (20) are provided, vortex formation inside the control chamber (10) is facilitated.
  • the fuel, entering into the control chamber (10), obstructs the rotation of the fuel existing inside the control chamber (10); however, in the subject matter injection valve, the fuel, entering into the control chamber (10), facilitates the rotation of the fuel existing inside the control chamber (10).
  • the inlet channels (20) are provided at different heights as mentioned, the intersections of the fuel during entry of the fuel through the inlet channels (20) are prevented.
