Definitions

  • the invention relates to an exhaust gas recirculation device for an internal combustion engine with an exhaust manifold coming from an exhaust system of the internal combustion engine, the fluidically via a rotary valve with air intake ducts of the Internal combustion engine is in communication, wherein the rotary valve a housing has a disk-shaped attached to a rotation axis Switching element corresponding to a control surface having openings, which exhaust control channels are assigned.
  • Such an exhaust gas recirculation device is known, for example, from DE-A1-199 41 035 known.
  • This document describes an exhaust gas recirculation device, the interacts directly with the air inlet ducts of the internal combustion engine.
  • a switching element of an exhaust gas recirculation valve is characterized by a along the Air intake ducts extending drive shaft adjustable. This embodiment takes up a relatively large amount of space and is also susceptible to faults external influences.
  • an exhaust gas recirculation device in which a Exhaust manifold via a rotary valve fluidly with an air inlet duct is connectable.
  • the rotary valve has a housing, on which a Drive module is mounted for actuating the rotary valve.
  • a disc-shaped Switching element corresponds to a control surface, which has an opening through which the fluidic connection by turning the Switching element can be produced.
  • the drive module is via a coupling member with the axis of rotation of Switching element connected.
  • the openings of the control surface prefferably have geometric shape, such. circular, elliptical, angular, etc. such, that a certain flow characteristic can be defined.
  • ceramics As a material for the control surfaces, ceramics has proven to be advantageous.
  • the disc-shaped switching element shown in the example is for a Four-cylinder internal combustion engine in cross-section circular with corresponding Passage openings or cross-shaped.
  • FIG. 1 shows a perspective view of an exhaust gas recirculation device according to the invention 1, in the for better illustration, the front housing was omitted.
  • a part of an exhaust manifold 2 is shown, the opens into a housing 3.
  • This exhaust manifold 2 is via a rotary valve 4 connected to exhaust gas control channels 5, which in turn to known Way open in not shown air intake ducts of the internal combustion engine.
  • the housing 3, a drive module 6 for the rotary valve 4 is arranged.
  • FIG 2 shows the exhaust gas recirculation device of Figure 1 in section.
  • the drive module 6, which is designed in a known manner as an electric drive module, drives a shaft 7, which via a coupling member 8 with a rotation axis 9 of a Switching element 10 is connected.
  • the disk-shaped, in cross-section circular switching element 10 driven by a driver 11, wherein the switching element 10 is gimbaled to the driver 11 is.
  • the switching element 10 has passages 12 for exhaust gas recirculation on, (see Figure 1) which correspond to openings 13 of a control surface 14.
  • the Openings 13 are, as Figure 2 clearly shows, the exhaust gas control channels 5 assigned.
  • the control surface 14 is in the present embodiment of a made ceramic material and has scraping edges 15, the one possible allow frictionless adjustment of the switching element 10 and deposits should prevent.
  • the further is the Switching element 10 by a spring 16, which is supported on the axis of rotation 9, opposite biased the control surface 14, whereby in the closed state the rotary valve 4, the tightness is ensured.
  • the openings 13 of the control surface 14 may have a defined geometric shape such as e.g. circular elliptical, angular, etc., such that in this way a specific flow characteristic for the exhaust gas recirculation flow is definable.
  • FIG 3 shows an alternative embodiment of the switching element 10, which in this case is cross-shaped, wherein the intermediate spaces 17 with the Openings 13 of the control surface correspond.
