Definitions

  • the invention relates to a device for transmitting a deflection of an actuator, in particular a piezo actuator of an injection valve, with at least one first lever device that has a first transmission element that transmits the deflection of the actuator.
  • Actuators that are based on the piezoelectric principle are suitable for the highly precise and very fast control of actuating processes, such as are expedient, for example, for controlling injection devices or valves of internal combustion engines.
  • these In order to realize larger linear deflections of the piezo actuators, these must consist of a large number of individual piezoelectric elements stacked on top of one another. This has the disadvantage that the size assumes impermissible dimensions for some purposes.
  • the installation space for injection valves in the cylinder head of an internal combustion engine is limited in such a way that there is generally no space for piezo actuators in the length dimension required for the desired adjusting movements. For this reason, smaller piezo actuators are used, the linear deflections of which are translated into larger deflections by means of suitable lever devices.
  • an injection valve in which mechanical transmission elements are provided for the transmission and translation of a deflection of a piezo actuator to an actuator, which essentially have the shape of a cylinder, the boundary surfaces of which are essentially triangular , with the corners rounded. Flat contact areas are formed by the width of the transmission elements.
  • O-rings have already been used for this purpose.
  • the use of O-rings is problematic in that O-rings can be damaged relatively easily. This problem is exacerbated by the fact that damage to a 0-ring cannot be reliably determined during a subsequent inspection.
  • a metallic seal of the actuator space therefore offers advantages, and in preferred embodiments it can be provided that the sealing surfaces run perpendicular to the actuator axis.
  • the surface pressure required for the sealing function can be applied, for example, via a connection thread.
  • the guidance of the transmission element is not non-positively fastened to the actuator, but can move spatially within the clearance tolerance. This mobility can cause kinematic changes and thus scatter in the stroke ratio.

  • the first spring element and / or the second spring element or the third spring element has a spring characteristic which is flat in relation to the force generated in each case.
  • the sealing force is reduced by the pre-tensioning forces, which is why high accuracy requirements are placed on them.
  • the spring elements are designed in such a way that the forces exerted by them on the first transmission element are just zero, it being possible for there to be a slight play between at least one spring element and the first transmission element.
  • the device according to the invention for transmitting a deflection of an actuator it is furthermore provided that it has a second lever device which surrounds a second transmission element. summarizes, wherein the deflection of the first transmission element is transmitted to the second transmission element.
