Definitions

the invention relates to an exhaust gas recirculation valve after Preamble of claim 1.
US 4,646,705 describes an exhaust gas recirculation valve in which a disc-shaped valve element eccentrically on a Spindle is attached, so in addition to a lifting motion, the required for opening the valve, a forced Rotary motion takes place, which is used to the effect that Impurities are rubbed off.
An exhaust gas recirculation valve according to the preamble of claim 1 is known from EP 1 111 227 A2 and sees in this case that a valve element at least at the beginning of the Opening process not only raised but also turned becomes. This can also be done under the Opening process solved impurities and adhesions become.
the invention is based on the object, an improved Exhaust gas recirculation valve to create, even with more extensive Contaminants work reliably.
a drive element is through the Rotary drive driven by rotation and constitutes part of the Turn-stroke conversion mechanism.
Driving element which, as mentioned, by the rotary drive is rotatably driven, by the rotary-hub conversion mechanism as a result of a rotation lifting and lowered.
this is done by the drive element raising and lowering a valve element around the opening and closing the valve effect.
the drive element and a valve element in which it is e.g. around a valve lifter with an attached Valve disc can act, connected in such a way that lifting and lowering the drive element or generally a translational movement transferred to the valve element becomes.
the drive element is connected to the valve element However, at least in the opening direction rotatably connected.
These rotatable connection can be direct or indirect be provided.
that can be Valve element when opening together with the drive element but it does not necessarily open when opened rotated. This is a difference and more crucial Advantage to the previously known arrangements in which always forcibly a rotation of the valve element together with the lifting movement took place.
the measure according to the invention offers the advantage of opening the valve even then possible if a stubborn bonding or Contamination of the valve element in its (rotational) position holds.
the exhaust gas recirculation valve according to the invention is Drive element at least in the opening direction with respect to the (as a result of adhesive bonds) stuck Rotatable valve element. Therefore, the rotation of the Drive elements even when a seizing of the valve element not prevented, and by the rotary-hub conversion mechanism this rotation becomes a lifting movement converted, so that the valve can be opened trouble-free can. Overall, this allows trouble-free operation be guaranteed.
inventive Exhaust gas recirculation valve can through the between the Drive element and the valve element acting friction one Setting to do so, with what force a Twisting of the valve element should take place, and from which Threshold a rotation between the drive element and the valve element should be allowed to a To avoid blocking.
rotatable, direct or indirect connection between Drive element and valve element even at a Exhaust gas recirculation valve may be provided, the one translational drive, for example a solenoid, having instead of the rotary drive.
a Exhaust gas recirculation valve can also be used to open Bonding to solve a twist of the valve element be provided. This can be done by a rotary-hub conversion mechanism be achieved, the the translational drive movement in an at least slight rotation of the valve element converts. With In other words, a drive element in this case twisted due to the translatory movement.
the Driving element in all directions, i. also in Closing direction, with respect to the valve element is rotatable.
the rotating-hub conversion mechanism becomes a helical path preferably, in the at least one fixedly mounted and rotatably mounted roller is arranged.
the drive element in this preferred case
a groove in the form of a comparatively short lentline provided.
a groove flank is supported on the groove arranged in the groove Roll off and thereby causes due to the rotation of the Driving element of a translational movement of the same, the can be used for opening and closing the valve.
valve element any suitable designs are conceivable, is currently for the inventive Exhaust gas recirculation valve preferred that the valve element a Valve tappet with an attached valve disc is.
the valve stem is rotatable but axially fixed with connected to the drive element to those described above
the valve lifter which in this case is part of the rotary-hub conversion mechanism is solid in every way Drive element is connected, and the valve disc with respect the valve stem is rotatable. This can also be a Opening the valve by a stroke even then be realized when the valve disc at its valve seat liable, what in a forced rotation of the Ventiltellers would cause a blockage of the valve.
the exhaust gas recirculation valve 10 shown in FIG. 1 has in its Upper area first, some housing parts and connections for the existing bearing feedback sensors and the like on.
the description may focus on how the operation as a result of a Rotation of a gear 12 takes place.
any Drive such as a torque or DC motor is conceivable.
a so-called Drive element is driven in rotation. In the illustrated Example, this is done via said gear 12, the over two driving pins 46, of which in the figure only one is recognizable, is connected to the drive element 14, the has substantially the shape of a sleeve.
a Provided spring 48 which is designed as a torsion spring and biases the drive element into the closed state, so that even with a malfunction of the drive a Reliable closure is possible. Acting on this spring it is a spiral or so-called watchmaker's spring, the is deformed at an opening of the valve so that they applying a rotational force in the closing direction.
a track 16 which forms a section represents a fferline.
a role 18th Die Roller 18 is on an axis 20 with respect to the housing 22nd fixedly mounted and rotatable about the axis 20.
the valve element in the case shown the valve tappet 32, with respect to the drive element 14th rotatably mounted. This is done in the example shown by means of the bearing bush 36.
the rotary-hub conversion mechanism in the form of the screw 16 and role 18 act and lifting the drive member 14 and thus open the valve. This can be a trouble-free opening and overall trouble-free Operation can be realized.
a seal be.
the exhaust gas recirculation valve 10 in addition in a perspective view and with more Components, such as a rotary motor 40, shown.
the rotation of the motor is via different gears 42nd on a gear 12, which is slightly different than the Embodiment of Fig. 1 is arranged, and from there on the drive element 14 transmitted.
Fig. 2 is in addition to recognize that the drive element 14 for manufacturing reasons can be designed in two parts. This is especially true then as exemplified, realized when by the Divide the drive element 14 and a division of the Screwing 16 is done so that these in other words by the combination of the two parts of the drive element is trained.
a Torsion spring 44 can be ensured that the valve is biased into a closed position, so too at a fault in the area of the rotary drive 40 a reliable closing done.
