Description

  

  Automatisch in Abhängigkeit von der     Kühlwassertemperatur    betätigte Einrichtung  an Automobilen     zum        Drosseln    des     Kühlluftstromes.       Die vorliegende Erfindung betrifft eine  automatisch in Abhängigkeit von der Kühl  wassertemperatur betätigte Einrichtung an  Automobilen     zum    Drosseln des Kühlluft  stromes und     besteht    in einer     Abschirmstore,     die mit einer motorisch     angetriebenen,    in Ab  hängigkeit von der Kühlwassertemperatur       betätigten    Zugvorrichtung in Verbindung  steht, derart,

   dass sie bei     überschreitiuig    einer  vorbestimmten     Kühlwassertemperatur    im  Sinne einer Freigabe des Kühlluftstromes     und     bei Unterschreitung einer tieferen Tempera  tur im Sinne einer Drosselung des Kühlluft  stromes     bewegt    wird.  



  Ein     Ausführungsbeispiel    der     Erfindung     ist in der beiliegenden     Zeichnung    dargestellt.  Dabei     zeigt:          Fig.1    die Einrichtung an einem Auto  mobil und       Fig.    2 die gleiche Einrichtung schematisch  zur Veranschaulichung des Zusammenwirkens  der einzelnen Organe.  



  Mit 1 ist der Kühler eines Automobils und  mit 2 der Motor bezeichnet. Hinter der Luft-,       eintrittsjalousie    4 sind parallel nebeneinander  zwei Führungsschienen 10 für     eine        Abschirm-          store    9 angeordnet, die aus     Textilstoff,          Plastiematerial    oder dergleichen besteht. Eine  Speicherrolle 5, die unter Wirkung einer       Torsionsfeder    steht, ist bestrebt, die Store 9       stets        aufzuwickeln    und damit den Kühlluft  strom freizugeben.

   Am obern Ende der Store  9 ist. ein Zugseil 6 über eine     Umlenkrolle    7 zur    Wickelrolle 8 eines     Gleichstrommotors    3 ge  führt, der über die Leitungen 11, 12 und 13  mit der Batterie des Automobils     sowie    mit  einem Umschalter 15 verbunden ist. Das be  wegliche Schaltglied 14 dieses     Umschalters    15  steht unter Wirkung eines im Kühler 1 oder  in der     Kühlwasserrückleitung    eingebauten       Balges    16, so dass es je nach der Temperatur  des Kühlwassers in die Schaltstellung V oder  R verstellt wird.  



  In der Schaltstellung V, also bei einer vor  bestimmten obern     Grenztemperatur,    dreht  sich der Motor 3 so, dass die Store 9 in Pfeil  richtung entgegen der Kraft der in der       Speicherwalze        eingebauten        Torsionsfeder    im  Sinne einer     Drosselung    des     Kühlluftstromes     bewegt wird.  



  In der Schaltstellung R, das heisst bei  einer     vorbestimmten        untern    Grenztemperatur,  dreht sich der Motor in entgegengesetzter  Richtung, so dass sich die Store auf die  Speicherrolle 5     aufwickelt    und dadurch im  Sinne einer Freigabe des     Luftstromes    bewegt  wird.



  Device on automobiles to throttle the flow of cooling air, activated automatically as a function of the cooling water temperature. The present invention relates to an automatically operated in dependence on the cooling water temperature device on automobiles to throttle the cooling air flow and consists in a shielding door that is connected to a motor-driven pulling device operated as a function of the cooling water temperature, such as

   that it is moved when a predetermined cooling water temperature is exceeded in the sense of a release of the cooling air flow and when falling below a lower temperature in the sense of a throttling of the cooling air flow.



  An embodiment of the invention is shown in the accompanying drawing. 1 shows the device on an automobile and FIG. 2 shows the same device schematically to illustrate the interaction of the individual organs.



  1 with the radiator of an automobile and 2 with the engine. Behind the air inlet louvre 4, two guide rails 10 for a shielding store 9 are arranged parallel to one another and are made of textile, plastic or the like. A storage roller 5, which is under the action of a torsion spring, strives to always wind up the store 9 and thus to release the cooling air stream.

   Store 9 is at the top. a pull rope 6 leads ge over a pulley 7 to the winding roller 8 of a DC motor 3, which is connected via lines 11, 12 and 13 to the battery of the automobile and to a switch 15. The movable switching element 14 of this switch 15 is under the action of a bellows 16 built into the cooler 1 or the cooling water return line, so that it is moved into the switching position V or R depending on the temperature of the cooling water.



  In the switching position V, i.e. at a certain upper limit temperature, the motor 3 rotates so that the store 9 is moved in the direction of the arrow against the force of the torsion spring built into the storage roller in the sense of a throttling of the cooling air flow.



  In the switch position R, that is to say at a predetermined lower limit temperature, the motor rotates in the opposite direction, so that the store winds up on the storage roll 5 and is thereby moved in the sense of a release of the air flow.
