Description
"l'hermostatischer Temperaturregler"."l'hermostatic temperature regulator".
Die-Neuerung bezieht sich auf einen thermostatischen Temperaturregler, insbesondere zur Verwendung im Kühlsystem von Brennkraftmaschinen.The innovation relates to a thermostatic temperature controller, in particular for use in the cooling system of internal combustion engines.
Bekanntlich werden für die Temperaturregelung des umlaufenden Kühlwassers von Brennkraftmaschinen Thermostate verwendet, bei denen das thermostatische Element in einem druckfesten Hohlkörper eine Ausdehnungsmasse enthält, die ein den Kühlwasserumlauf regelndes federbelastetes Ventil beeinflusst.As is known, for the temperature control of the circulating cooling water used by internal combustion engines thermostats, in which the thermostatic element in a pressure-resistant hollow body contains an expansion mass, which a circulation of the cooling water regulating spring-loaded valve influenced.
Bei bekannten Ausführungen derartiger Regler besteht der Nachteil, dass bei Versagen des thermostatischen Elements, z. B. bei Undichtwerden, ein selbsttätiges Öffnen des Ventils bei der vorgeschriebenen Temperatur des Kühlwassers-nicht erfolgt. Dadurch ergeben sich unzulässig hohe Kühlwassertemperaturen, die zu Störungen oder Beschädigungen des Motors führen können.Known designs of such regulators have the disadvantage that if the thermostatic element fails, e.g. B. in the event of a leak, an automatic one The valve does not open at the prescribed temperature of the cooling water. This results in impermissibly high cooling water temperatures, which can lead to malfunctions or Damage to the engine.
Aus diesem Grunde ist schon vorgeschlagen worden, in den thermostatischen Reglern Schmelzsicherungen anzuordnen. Bekannte Ausführungen dieser Art bestehen darin, dass in dem Ventilteller des Reglers Öffnungen angebracht sind, die durch Schmelzstifte oder-stopfen Z. b. aus niedrig schmelzenden Legierungen verschlossen sind. Bei Überschreitung der zulässigen Kühlwassertemperatur schmelzen diese Stopfen, wodurch die Öffnungen in dem Ventilteller freigegeben werden, so dass das Kühlwasser durch die Öffnungen unmittelbar in den Kühler der Maschine einfliessen kann.For this reason it has already been suggested in the thermostatic Arrange regulators fuses. Known designs of this type exist that in the valve disk of the regulator openings are made through Hot melt pins or plugs Z. b. made of low-melting alloys closed are. If the permissible cooling water temperature is exceeded, these melt Plug, whereby the openings in the valve disc are released, so that the cooling water can flow through the openings directly into the cooler of the machine.
Es hat sich aber herausgestellt, dass mit diesen Schmelzsicherungen keine zuverlässige Abdichtung der Öffnungen des Ventiltellers bei normalem Betrieb gewährleistet ist.It has been found, however, that with these fuses no reliable sealing of the openings of the valve disk during normal operation is guaranteed.
Ausserdem führt der Einbau dieser vorgeformten Verschlußstopfen, z. H. durch Vernieten oder Verschrauben, häufig zu Beschädigungen der empfindlichen Teile des Reglers.In addition, the installation of these preformed plugs such. H. by riveting or screwing, often to damage the sensitive Parts of the regulator.
Diese Nachteile werden durch die Neuerung beseitigt, und zwar dadurch, dass eine thermoplastische Masse als zusammenhängende Füllung eines ringschalenförmigen Hohlraums sämtliche Öffnungen des Ventiltellers abdeckt. In einer zweckmassigen Ausbildung der Neuerung ist der die thermoplastische hasse enthaltende Hohlraum unmittelbar am Ventilteller angeformt. Nach einem weiteren Merkmal der Neuerung kann die thermoplastische Masse auch in einem zum Ventilteller konzentrisch angeordneten und durch Federwirkung gegen den Ventilteller gedrückten topfartigen Behälter eingebettet sein, dessen Boden und/oder Umfangswand eine oder mehrere Durchlassöffnungen aufweist.These disadvantages are eliminated by the innovation, namely by that a thermoplastic mass as a coherent filling of an annular shell-shaped Cavity covers all openings in the valve disk. In an expedient The innovation is the cavity containing the thermoplastic hate Formed directly on the valve plate. According to another feature of the innovation the thermoplastic mass can also be arranged in a concentric to the valve disk and cup-like container pressed by spring action against the valve disk be whose bottom and / or peripheral wall has one or more passage openings.
Anhand der Abbildungen 1 und 2 sind zwei Ausführungsbeispiele der Neuerung dargestellt.Based on the figures 1 and 2 are two embodiments of the Innovation presented.
Nach Abb. 1 besteht der thermostatische Temperaturregler aus dem druckfesten Hohlkörper 1, in welchem der Gummikörper 2 angeordnet ist. Dieser bildet mit der Umfangswand des Hohlkörpers 1 den Hohlraum 3, der zur Aufnahme der Ausdehnungsmasse dient. Der Gummikörper 2 umfasst den Stössel 4, der an seinem unteren Ende konisch zugespitzt und an seinem oberen Ende mit dem Ventilteller 5 verbunden ist. Der Ventilteller wird von den Zugfedern 6 auf den Ventilsitzring 7 gezogen. Der Ventilteller ist mit den Öffnungen 8 versehen.According to Fig. 1, the thermostatic temperature controller consists of the pressure-resistant one Hollow body 1 in which the rubber body 2 is arranged. This forms with the Circumferential wall of the hollow body 1, the cavity 3, which is for receiving the expansion mass serves. The rubber body 2 includes the plunger 4, which is conical at its lower end pointed and connected to the valve disk 5 at its upper end. The valve disc is pulled onto the valve seat ring 7 by the tension springs 6. The valve disc is provided with the openings 8.
Unterhalb des Ventiltellers ist der topfartige Behälter 9 angeordnet, der die Öffnungen 10 aufweist und mit der thermoplastischm i/Lasse 11 ausgefüllt ist. Durch die . druckfeder 12 wird der Behälter 9 gegen den Ventilteller 5 gedrückt.The pot-like container 9 is arranged below the valve disk, which has the openings 10 and with the thermoplastic mix 11 is filled out. Through the. Compression spring 12 is the container 9 against the valve plate 5 pressed.
Der thermostatische Temperaturregler gemäss der Neuerung arbeitet in der kiese, dass bei Versagen des thermostatischen Temperaturreglers, d. h. bei Auftreten von unzulässig hohen l hlwassertemperaturen die thermoplastische Kasse 11, die bei einer höheren Temperatur flüssig wird, als die in den Füllraum 3 befindliche Ausdehnungsmasse durch die Öffnungen 8 und 10 austritt. Auf diese Weise wird im Falle des Nichtöffnens des Ventils erreicht, dass das Kühlwasser durch die von der plastischen Masse 11 freigegebenen Öffnungen 10 und 8 hindurchfliessen kann.The thermostatic temperature controller according to the innovation works in the gravel that if the thermostatic temperature controller fails, i. H. at If impermissibly high oil temperatures occur, the thermoplastic cash register 11, which becomes liquid at a higher temperature than that in the filling space 3 Expansion mass exits through openings 8 and 10. In this way, the If the valve is not opened, the cooling water passes through the plastic mass 11 released openings 10 and 8 can flow through.
Hach dem Beispiel in Abb. 2 ist die thermoplastische Masse 11 in der ringschalenförmigen Vertiefung 13 des Ventiltellers 5 eingebettet. Bei Versagen des Temperaturreglers tritt die flüssig gewordene thermoplastische Masse 11 unmittelbar nach aussen und gibt dem Kühlwasser den Weg durch die Öffnungen 10 frei.According to the example in Fig. 2, the thermoplastic mass 11 is in the annular shell-shaped recess 13 of the valve disk 5 embedded. In case of failure of the temperature controller, the thermoplastic mass 11 which has become liquid occurs immediately to the outside and gives the cooling water its way through the openings 10.
