Definitions

  • the invention relates to a highly dynamic servo-valve control device with a tax-containing in a base body sleeve and a tax-containing in the body tax-carrying slide, wherein at least one of the control edges of the slider is designed to be displaceable relative to a control edge of the sleeve, wherein the slide and the sleeve to each other the servo valve control device comprises a primary drive device and a high frequency drive device, wherein the primary drive device comprises at least one pilot valve which influences the movement of the sleeve or the slide.
  • Highly dynamic servo-valve control devices are known from the prior art. These servo-valve control devices are used in the prior art to control or regulate flow rates and / or pressures in hydraulic systems. In order to change volume flows, control cross sections are changed via a movement of control edges, for example on a slide and with the aid of a direct or indirect drive.
  • Valve control is disclosed in British Patent GB 677,672A. From the European patent application EP 1 098 101 A2 a further valve control device is known. U.S. Patent 4,205,590 A also discloses another valve control device, as does U.S. Patent 4,333,387 A.
  • Directly controlled valves include electromechanical converters, proportional solenoids, linear motors, plunger coils or piezoelectric transducers. Pilot-operated valves are indirectly operated drives, such as mechanical-hydraulic converters, spool valves, nozzle baffle plates and jet pipes. High dynamic servo valve control devices include both direct and pilot operated valves.
  • control cross sections are bounded by two control edges, wherein the prior art, an active, i. in its position variable control edge, such as on the slider and a passive, i. fixed control edge, about on the sleeve includes.
  • the achievable frequency of the servo-valve control device is specified in the existing cases via a drive of the slide and an associated drive or control electronics.
  • the high-frequency drive device comprises a piezoelectric element or a plunger coil.
  • the servo-valve control device comprises a sleeve position determining device for determining a position of the sleeves relative to a position of the slider. In such an embodiment, it is possible to determine the exact position of slide to sleeve and accordingly to operate the servo-valve control device.
  • the sleeve position determining device comprises an eddy current sensor.
  • a non-contact eddy current sensor is wear-free and robust. Also, it is extremely resistant to corrosion, which increases the longevity of the servo-valve control device.
  • the servo-valve control device has an absolute position determining device for determining the position of the sleeve and slide in relation to the main body, the exact position of sleeve and slide can be advantageously determined in this variant in this variant. This allows avoiding drift of sleeve and slider in the body. Thus, a fault-free operation of the servo-valve control device is made possible even over long periods of use. An absolute measurement is only necessary if the slide and sleeve are pilot-operated.
  • the sleeve position determining device or the absolute position determining device comprises an eddy current sensor, a Hall effect sensor, or an inductive displacement transducer (LVDT). Since, for example, the use of the property that a movement of electrons in the magnetic field is influenced, and a resulting deflection as voltage on the Hall effect sensor can be tapped off, this has the advantage that this is very large magnetic fields can be measured and the measuring range of Hall effect sensors is significantly larger than other sensors.
  • the use of known measuring sensors in the sleeve position determining device or the absolute position determining device is particularly advantageous in this variant, since costs and troubles are avoided in the procurement of the corresponding sensors.
  • the servo-valve control device comprises at least one pilot valve controlling the movement of the sleeve and a pilot valve controlling the movement of the slide. It is thus used for slide and sleeve drive side robust and particularly small-sized elements.
  • the servo-valve control device comprises at least one high-frequency drive device.
  • a high frequency drive device has the significant advantage of having very short response times.
  • the high-frequency drive device controls at least one displacement of the sleeve. This minimizes the response time of the sleeve in the control.
  • the high-frequency drive device has a high inherent momentum and a low lift
  • the primary drive device has a low inherent dynamics and a large stroke.
  • the high-frequency drive device complements the primary drive device in terms of its own dynamics and speed increase in the expression, particularly fast control times become possible.
  • the combination of high dynamics / short stroke and medium (low) dynamics / long stroke results in a high speed gain.
  • the high-frequency drive device has a low momentum and a large stroke, and the primary drive means a high momentum and has a small stroke, so in a further variant, an exchange of high-frequency drive device elements with primary drive device elements is possible.
  • the advantage of a particularly fast control of the individual components of the servo-valve control device is nevertheless maintained.
  • the servo-valve control device 1 is shown in a section.
  • the servo-valve control device 1 comprises a base body 2 in which a sleeve 3 is mounted.
  • the sleeve 3 has control edges 5.
  • the control edges 5 are pronounced inside the sleeve 3.
  • a slide 4 In the interior of the sleeve 3, a slide 4, with a pronounced on the circumference of the control edges 5 displaceable within the sleeve 3 pronounced.
  • Through the sleeve 3 pass through openings.
  • the passage openings 14 are connected to passage openings 14 in the base body 2.
  • the sleeve 3 is designed displaceable via a high-frequency drive device 11 in this embodiment.
  • the high-frequency drive device 11 pushes the sleeve 3 in one direction.
  • the high-frequency drive device 11 comprises a piezoelectric element 13.
  • the piezoelectric element 13 has the advantage of a very fast response and pushes the sleeve 3 in one direction.
  • a return movement is effected by a spring 20.
  • the spool 4 is moved by pressurized liquids either in one direction or the other.
  • the liquids are conveyed by pilot valves 12 to one side or the other of the slide 4 from a prime mover 10.
  • the pilot valves 12 are supplied via the primary drive device 10, which has supply channels for the liquid supply to the pilot valves 12, preferably with an incompressible liquid.
  • the supply channels are connected to the pilot valves.
  • supportive also offers the use of the spring 20.
  • the position of the slider 4 in the sleeve 3 is determined by an incorporated in the sleeve 3 eddy current sensor 7, which is part of a sleeve position determining means 6.
  • the housing 2 and an absolute position determining device 8 is incorporated.
  • the Hall effect sensor 9 is thus located between the housing 2 and sleeve 3.
  • the sleeve position determination device 6 and the absolute position determination device 8 comprise further sensors known from the prior art.
  • the primary drive device 10 and the high-frequency drive device 11 also use standard known elements from the prior art.
  • the movement of the sleeve 3 via a force flow through a transmission medium such as an incompressible fluid, e.g. Oil advantageously reachable, wherein the movement of the slider 4 is also achieved via a transmission medium, such as an incompressible liquid such as oil.
  • a transmission medium such as an incompressible fluid, e.g. Oil
  • the two transmission media are controlled separately from each other. However, the possibility of a predefined forced coupling between the two transmission media can also be used.
  • the slide can be designed to be displaceable in both directions by the action of the transmission medium alone.
