Definitions

  • the invention has for its object the structural effort for a regulated Exhaust gas recirculation and a shutdown of the exhaust gas recirculation in engine braking mode to keep it as low as possible.
  • the axial displaceability of the stop for the sealing element makes it possible to to vary the effective valve cross-section so that the recirculation rates for the exhaust gas can be regulated.
  • the sealing element can also function as a barrier take over with engine braking operation. Since the check valve according to the invention is multifunctional, considerable savings are made in construction costs and volume.
  • An advantageous embodiment of the movable stop can claim 3 be removed.
  • the stop can be moved axially by the cam and allows the control of the valve cross-section up to the complete shut-off.
  • valve cross section Another advantageous possibility for regulating the valve cross section can be Remove claim 4. Because the sealing element is designed as an elastic tongue or plate which is regulated directly by the cam becomes an inexpensive solution reached.
  • FIG. 1 shows in section I-I an inventive check valve for exhaust gas recirculation.
  • the check valve consists essentially of the valve body 1 with openings 2, a sealing element 3, a spring plate 4 and a stop 5.
  • the stop 5 is axially displaceable along a spindle 9, so that the movement of the sealing element 3 can be limited.
  • the stop 5 against the restoring force of a coil spring 6 by cooperation with an actuating element 7 in the form of a cam 8 moves.
  • the rotation of the cam 8 can in a not shown here Way by a crank and a cylinder connected non-rotatably to the cam 8 be accomplished.
  • FIG. 2 shows a top view of the valve body 1 with openings 2.
  • the check valve according to the invention is multifunctional.
  • valve In the uppermost position of the stop 5, the valve is in the closed position by the Sealing element 3 completely closes the openings 2.
  • the valve thus fulfills the Function of a throttle in engine braking mode.
  • the stop 5 will be down moves so that the sealing element can open a predetermined stroke H.
  • the valve also fulfills the function of regulated exhaust gas recirculation.
  • FIG. 3 A further advantageous embodiment of the check valve can be seen in FIG. 3.
  • the sealing element 3 is designed here as a plate or tongue, which in is elastic and always on the cam 8 without pressurization by charge air is present.
  • the plate or tongue can be reinforced with a plate 11 be provided.
  • the direction of flow of the exhaust gas is indicated by an arrow indicated. If there are pressure peaks in the exhaust gas, this is opened by the charge air pressure sealing element 3 held in the closed position until it strikes the cam 8 and leads part of the exhaust gas back into the charge air line 10.
  • the hub can be controlled by the cam 8. If necessary, the sealing element 3 can be completely be brought into the closed position so that a special shut-off valve is not required can.
