  • the drive-related elasticity Through the drive-related elasticity, the one acting on the valve disk Exhaust gas pressure and the flow conditions in the intake duct result with a stepless adjustment, especially in part-load operation undesirable inaccuracies with small valve gaps.
  • the subject of the invention is a device for exhaust gas recirculation at on the one hand the exhaust gas feed channel, as well as the adjustment drive in the intake duct is arranged and on the other hand, the valve parts are formed in this way are that minimal of the exhaust gas and fresh gas flow caused forces on the closing element and its drive Act. To this end, it projects approximately perpendicular to the intake duct Fresh gas flow an essentially cylindrical exhaust gas supply pipe as part of an exhaust gas inlet connection, which in has an outlet opening in its cylindrical wall. about the outlet opening is a rotary valve bell as a closing element arranged, which protrudes into the intake duct Exhaust gas supply pipe includes at least in some areas. The rotary valve bell is with an electric swivel motor serving as an adjustment drive coupled.
  • the electric swivel motor is, for example, a so-called electromagnetic one Turntable.

  • the resulting torque of the rotor acts against one Return spring.
  • the Coil winding together with an iron yoke and a stator The permanent magnet together with the swivel shaft form the rotor.
  • the pivoting movement of the closing element can also be done with Can be realized with the help of a stepper motor.
  • the closing element or the rotary valve bell is aligned opposite the exhaust gas supply pipe and the exhaust gas supply pipe.
  • the center lines of the exhaust gas supply nozzle and the Rotary vane bell can also be slightly offset in parallel be arranged.
  • An offset that has a small gap in the area the outlet and a large gap on the opposite Generated side of the exhaust gas supply pipe, causes good valve tightness without the risk of the rotary valve bell jammed by dirt in the gap.
  • the exhaust gas recirculation device has a closing element, due to its design only a small amount to operate Force is needed.
  • the bell shape the locking element on the one hand a high security against one vibration excitation from the exhaust system and the other it is shake-proof due to a balanced mass distribution with respect to their swivel axis.
  • Furthermore enables the direct drive has a highly dynamic and precise adjustment behavior.
  • Figure 1 shows an exhaust gas recirculation valve in an intake duct (10) an internal combustion engine is arranged.
  • the intake duct (10) is behind in the direction of the fresh gas flow the exhaust gas is introduced into a throttle valve (1).
  • This is at the Outside wall of the intake duct (10), an exhaust gas supply nozzle (11) arranged on which an exhaust gas feed line, not shown here is flanged.
  • an exhaust gas supply nozzle (11) arranged on which an exhaust gas feed line, not shown here is flanged.
  • the Exhaust gas supply pipe (12) which is also connected to the exhaust gas supply nozzle (11) molded tubular portion a cylindrical outer contour and is with a bottom (13) locked.
  • Part of the exhaust gas supply pipe (12) has a round outlet opening (15).
  • the imaginary center line of the outlet opening (15) runs, for example, parallel to the center line of the intake duct (10).
  • Part of the exhaust gas supply pipe (12) is a pivotable one Rotary vane bell (20) positioned.
  • the pivot axis of the Rotary vane bell (20) corresponds to the center line of the exhaust gas feed pipe (12).
  • the rotary valve bell (20) is a thin-walled in Figure 1 Master cylinder with bottom. On the outside of the bottom is a smaller diameter cylinder concentric with the master cylinder arranged.
  • the master cylinder has one as a rotary valve opening serving bore (21), with the exhaust gas recirculation valve open with the outlet opening (15) for example is congruent. Since the exhaust gas recirculation valve in FIG is shown closed position, the rotary valve opening (21) on the back of the exhaust gas supply pipe (12) and is therefore only drawn in dashed lines.
  • the outlet opening (15) of the exhaust gas supply pipe (12) and the rotary slide valve opening (21) can have different sizes and surfaces have different contours.
  • the cross sections of the openings (15) and (21) can be coordinated with one another, if necessary, that each pivot angle of the rotary valve bell (20) corresponds to a certain opening cross section, so that e.g. With increasing pivoting angle the opening cross section increases.
  • the rotary vane bell (20) can also have several Have openings in the area of the master cylinder. To this For example, different opening cross sections per Realize swivel angle.
  • the bottom of the rotary valve bell (20) can have several recesses or have holes to exhaust gas that is in the gap between the exhaust gas supply pipe (12) and the rotary valve bell (20) pending to let escape.
  • No recesses can affect the rotary valve bell (20) train acting axial force. It also penetrates the edge of the Exhaust gas escaping from the floor is not in the adjustment drive (30) on.
  • a Electric swivel motor (30) used to store and adjust the rotary valve bell (20. It is in a drive housing (31) housed in the form of a tube from the Intake channel (10) protrudes.
  • the drive housing (31) is like this aligned that its center line with the center line of the Hole for receiving the exhaust gas supply pipe (11) matches and at the same time with the center line of the intake duct (10) cuts vertically. Furthermore, the outside facing end face of the drive housing (31) normal to the housing center line aligned.
  • a rotary slide flange (32) is mounted on which is followed by a rotary valve axis (35).
  • the free The end of the rotary valve axis (35) engages in one in the floor (13) of the exhaust gas supply pipe (12) existing bearing bore (16).
  • the rotary valve bell (20) sits with the help of the bearing cylinder on a hollow shaft (36) on the rotary valve axis (35) is double-bearing. That near the rotary valve flange (32) arranged roller bearing (37) is a fixed bearing. If necessary, the drive housing (31) with slight Overpressure to be applied to the rolling bearing before possibly penetrating To protect exhaust gas particles. In addition, before free end of the hollow shaft (36) between the rotary valve bell (20) and the rotary valve axis (35) or the bottom (13) for example, a gap seal can be provided before free end of the hollow shaft (36) between the rotary valve bell (20) and the rotary valve axis (35) or the bottom (13) for example.
  • Coil (41) One sits on the rear part of the hollow shaft (36) Coil (41). Among other things these two components form the rotor of the Electric swivel motor (30). Around the coil (41) is a magnetic stator (42) arranged. It is in one in the rotary valve flange (32) existing annular groove (33) attached.
