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 fluidic via a rotary slide valve with air inlet channels Internal combustion engine is connected, the rotary slide valve being a housing has with a disk-shaped attached on an axis of rotation Switching element which corresponds to a control surface which has openings, to which exhaust gas control channels are assigned.
  • Such an exhaust gas recirculation device is, for example, from DE - A1 - 199 41 035 known.
  • This document describes an exhaust gas recirculation device that interacts directly with the air intake ducts of the internal combustion engine.
  • a switching element of an exhaust gas recirculation valve is by a along the Air inlet ducts adjustable drive shaft adjustable. This embodiment takes up a relatively large amount of installation space and is also prone to failure external influences.
  • the object of the invention is to avoid these disadvantages and an exhaust gas recirculation device to create the more compact in construction and less susceptible to interference external influences.
  • a drive module on the housing is provided for the rotary slide valve. That way a very compact design of the exhaust gas recirculation device is created.
  • the compact embodiment further reduces the susceptibility to failure, since now Drive module and exhaust gas recirculation valve are no longer arranged separately in the engine compartment are.
  • the drive module is connected to the axis of rotation via a coupling member of the switching element connected. It has proven to be advantageous that the openings of the control surface have a defined geometric shape, such as e.g. circular, elliptical, angular, etc. in such a way that a certain flow characteristic is definable.
  • Ceramic has proven to be advantageous as a material for the control surfaces proven, the control surface furthermore has scraping edges which are in contact with the switching element for the frictional forces between To keep the switching element and control surface as small as possible.
  • That in the example disk-shaped switching element shown is for a four-cylinder internal combustion engine circular in cross-section with corresponding through openings or cross-shaped.
  • the fact that the switching element by means of a The spring function is biased against the control surface, the sealing function of the exhaust gas recirculation valve guaranteed, it is particularly advantageous if that Switching element can be driven by a gimbal-connected driver.
  • Figure 1 shows a perspective view of an exhaust gas recirculation device according to the invention 1, in which the front housing wall for a better representation was omitted.
  • Part of an exhaust manifold 2 is shown, the opens into a housing 3.
  • This exhaust manifold 2 is via a rotary slide valve 4 connected to exhaust gas control channels 5, which in turn are known Way open air intake channels of the internal combustion engine, not shown.
  • a drive module 6 for the rotary slide valve 4 is arranged.
  • FIG. 2 shows the exhaust gas recirculation device from Figure 1 in section.
  • the drive module 6, which is designed in a known manner as an electrical drive module, drives a shaft 7, the one via a coupling member 8 with an axis of rotation 9
  • Switching element 10 is connected.
  • the disc-shaped, in cross section circular switching element 10 driven by a driver 11, the switching element 10 gimbally suspended on the driver 11 is.
  • the switching element 10 has passage openings 12 for exhaust gas recirculation on (see FIG. 1) which correspond to openings 13 of a control surface 14.
  • openings 13 are assigned to the exhaust gas control channels 5.
  • control surface 14 is made of one made of ceramic material and has scraping edges 15, the one as possible enable smooth adjustment of the switching element 10 and deposits should prevent.
  • this is furthermore Switching element 10 opposite by a spring 16, which is supported on the axis of rotation 9 the control surface 14 biased, whereby in the closed state of the rotary valve 4, the tightness is guaranteed.
  • the openings 13 of the control surface 14 can have a defined geometric shape have, such as circular elliptical, angular, etc., such that in this way a specific flow characteristic for the exhaust gas recirculation flow can be defined.
  • Figure 3 shows an alternative embodiment of the switching element 10, which in this case is cruciform, the spaces 17 with the Openings 13 of the control surface correspond.
