Definitions

  • the invention relates to an air duct system with a pipe section, in which a throttle valve rotatably mounted about an axis of rotation is arranged, the axis of rotation being associated with a force accumulator which moves the throttle valve against the air flow in the open position.
  • Such an arrangement is known for example from DE-OS 39 17 360 or DE-OS 41 35 758. It serves to regulate the air flow within an air duct system. This is done by rotating the throttle valve about the axis of rotation, the throttle valve more or less closing the free cross section within the pipe section.
  • the previously known devices for regulating the position of the throttle valve have the disadvantage that the regulation takes place only between two end positions, which ensure a maximum and a minimum air flow.
  • the maximum air flow is given when the throttle valve is approximately in the plane of the longitudinal axis of the pipe section located.
  • the minimum air flow depends on the energy accumulator, with the previously known systems not closing the pipe cross-section as much as possible, since the throttle valve always remains at an angle to the longitudinal axis. This is mainly due to the fact that the setting of the throttle valve during the operation of the air guidance system cannot be rigid, for example by means of a motor, but it is desired that the throttle valve can also adapt to differences in air flow quantities.
  • the force accumulator is therefore designed in such a way that the throttle valve changes continuously during operation of the air guidance system depending on the strength of the air flow, although the force accumulator leads back to a desired position. Damping of the throttle valve movement is usually carried out using a known damper.
  • the present invention has for its object to provide an air duct system of the above. To develop a way in which the control of the throttle valve movement is significantly improved and expanded.
  • a device is assigned to the axis of rotation which closes the throttle valve against the force of the energy accumulator.
  • the device for the final closing of the throttle valve should consist of a simple mechanical linkage so that the effort is kept as low as possible.
  • a push rod is therefore chosen which extends approximately in the direction of the longitudinal axis and engages with a hook in an adjusting disc, the adjusting disc in turn being placed on the axis of rotation.
  • the adjusting disk has the advantage that it also enables a connection to the damper described above and / or to the energy accumulator.
  • the pressure rod is acted upon by a pressure leg of a rotary lever, which rotary lever in turn rotates about a rotary pin.
  • the rotary lever protrudes in the direction of travel of a carriage, which strikes this rotary lever near its end position and rotates the rotary lever around the rotary pin, so that the pressure leg pressurizes the push rod.
  • the hook on the adjusting disc is eccentric to the center of the axis of rotation for the throttle valve in a position in which it guides the throttle valve into the final closed position.
  • This position is preferably arranged in a plane perpendicular to the above-mentioned longitudinal axis of the pipe section. That is, the hook follows the plane of the throttle valve during its eccentric rotary movement about the center of the axis of rotation. The most favorable leverage ratio is always achieved.
  • the application of the rotary lever to close the throttle valve is preferably carried out via a slide, which in turn is connected to a perforated strip, which is described for example in DE-OS 39 17 360.
  • This perforated strip engages with its holes with the teeth of a gear segment, which gear segment in turn is seated on a shaft of an engine.
  • a volume flow controller 2 is seated on a pipe section 1 of an air routing or air conditioning system, not shown.
  • This volume flow controller 2 essentially consists of an actual setting device 3 and a controller 4.
  • a throttle valve (not shown in detail) in the pipe section 1 is operated, which can be round or oval, depending on the cross section of the pipe section 1, or can take on a different geometric shape.
  • the throttle valve rotates about an axis of rotation 5.
  • the adjusting shaft 6 is placed on the axis of rotation 5, the adjusting disk 6 being coupled in a rotationally fixed manner to the axis of rotation 5.
  • the adjusting disc 6 is connected via a tension element 7, for example a ball chain, to a spring strip 8 and at its free end 9, opposite which an end, not shown in more detail, is fixed to a side wall 10 of a housing 11 for the adjusting device 3 .
  • the free end 9 of the spring strip 8 can lift off the side wall 10 in the y direction, the adjusting disc 6 then rotating in the z direction about the axis of rotation 5 and the throttle valve closes.
  • Such a position of the spring strip 8 is indicated by dashed lines.
  • the spring strip 8 is released by moving a slide 12 in the direction x, since the spring strip 8 is guided in a channel 13 of the slide 12, which is only indicated by dashed lines. If the carriage 12 is displaced in the direction x, more and more of the spring strip 8 is released, so that this spring strip 8 can yield to a train of the tension element 7. As a result, the throttle valve can in turn close more and more of the free cross section of the pipe section 1.
  • a rotary lever 15 which is arranged on a pivot pin 16.
  • This rotary lever 15 has a pressure leg 17 which strikes the rear end of a push rod 18.
  • This push rod 18 is on the one hand near the pressure leg 17 in a guide profile 19 slidably mounted against the direction x and on the other hand engages with a hook 20 in a hole in the adjusting disc 6.
  • the push rod 18 rests on a stop roller 21, which is also seated in the adjusting disc 6. Furthermore, the hook 20 is connected eccentrically to the axis of rotation 5 with the adjusting disc 6, so that after rotation of the adjusting disc 6 about the axis of rotation 5 in the direction of rotation z when the throttle valve is closed, a favorable force ratio for the push rod 18 is produced by the position of the Hook 20 is reached in the position then reached below the axis of rotation 5, wherein a connection of the tension element 7 with the adjusting disc 6 is above the axis of rotation 5.
  • the hook 20 is in the open position of the throttle valve shown in FIG. 2 approximately in the plane of the opened throttle valve, which is indicated by the dash-dotted longitudinal axis A of the pipe section 1.
  • This longitudinal axis A passes through a center M of the axis of rotation 5.
  • the hook 20 is in a plane which runs approximately perpendicular to the longitudinal axis A through the center M.
  • the carriage 12 is otherwise connected to a perforated strip 22 by means of profile strips (not shown in more detail), the corresponding holes 23 in the perforated strip 22 being able to be brought into engagement with a toothing 24 of a gearwheel segment 25.
  • the gear segment 25 is placed on a rotary shaft 26 which is connected to a motor (not shown in detail) in the controller 4. If the motor is started, it rotates the rotary shaft 26, the gear segment 25 displacing the perforated strip 22 in the direction x.
  • the perforated strip 22 takes the carriage 12 with it.
  • perforated strip 22 there is a scale 27 by means of which the position of the slide 12 can be read. Connecting elements between perforated strip 22 and slide 12 are identified by 28.
  • this ball chain is connected to the adjusting disk 6 by inserting the last ball into a slot 29. Near this slot 29 is the adjusting disk 6 via a rod 31 inserted into the adjusting disk 6 with a hook 30 connected to a damper 32.
  • This damper 32 is shown in DE-OS 41 35 758 and is therefore not described in detail here.
  • the damper 32 is connected on one side via shaft stub 33 to a mounting bracket 34, which in turn is fastened to the housing 11.
  • the task of the damper 32 is to counteract differences in the air flow within the pipe section 1, so that fluttering of the throttle valve is substantially avoided.
