Description

Thermostatisch gesteuertes Regelorgan für die Kühlmitteltemperatur in Verärennungskraftmaschinen. Bei der Verwendung thermostatisch gesteuerter Drosselorgane im Kühlmittelumlauf zur Regelung der Betriebstemperatur von Verbrennungskraftmaschinen hat es sich gezeigt, daß einerseits der Übergang von vollständiger Drosselung zur Freigabe des vollen Durchla13querschnittes innerhalb einer verhältnismäßig kleinen Temperaturspanne erfolgen muß, und daß andererseits zum Einhalten hoher Betriebstemperaturen, wie sie beispielsweise für schwere Brennstoffe benötigt werden, nur ganz geringe Bruchteile des freien Querschnittes erforderlich sind.Thermostatically controlled regulator for the coolant temperature in distortion engines. When using thermostatically controlled throttling devices in the coolant circulation to regulate the operating temperature of internal combustion engines it has been shown that on the one hand the transition from full throttling to Clearance of the full passage cross-section within a relatively small one Temperature range must take place, and that on the other hand, to maintain high operating temperatures, as are required, for example, for heavy fuels, only very small fractions of the free cross-section are required.

Beide Forderungen konnten bisher nicht gleichzeitig erfüllt «erden, da Thermostaten, die den Übergang vom vollen Schluß zu voller Öffnung und umgekehrt schon bei verhältnismäßig geringen Temperaturveränderungen sicherten, zur Regelung der für hohe Betriebstemperaturen erforderlichen minimalen Durchla13querschnitte nicht geeignet sind und zii starken Temperaturschwankungen führen.So far, both requirements could not be met at the same time. there are thermostats that make the transition from full closing to full opening and vice versa secured even with relatively small changes in temperature, for regulation the minimum passage cross-sections required for high operating temperatures are not suitable and cause strong temperature fluctuations.

Dieser Nachteil wird vermieden, wenn entsprechend (lern Erfindungsgedanken Regelzonen zwischen Offnungsbeginn und voller t iffnung geschaffen werden. Dabei kann zweckmäßig so verfahren werden, daß nach (@ffnungsbeginn zunächst größeren Temperaturschwankungen kleine Ouerschnittsänderungen, alsdann kleineren Temperaturschwankungen größere Querschnittsänderungen entsprechen, so daß also bei Anwendung eines solchen Verfahrens die Änderung der Durchlaßqtierschnitte unproportional zur Temperaturänderung erfolgt. Zweckmäßig kann die angestrebte Kurve der Änderung der Durchlaßquerschnitte hinter der normalen Öffnungskurve zurückbleiben.This disadvantage is avoided if you learn the ideas of the invention accordingly Control zones between the start of opening and full opening are created. Included can expediently be proceeded in such a way that after (@ the start of opening larger Temperature fluctuations small cross-sectional changes, then smaller temperature fluctuations larger cross-sectional changes correspond, so that when using such Procedure, the change in the Durchlaßqtierschnitte disproportionate to the temperature change he follows. The desired curve of the change in the passage cross-sections can expediently lag behind the normal opening curve.

Die Abb. i zeigt in graphischer Darstellung ein Beispiel einer Querschnittsänderung nach dein Erfindungsgedanken. a ist die Temperaturspanne, innerhalb derer der Übergang vom Z)ffnungsbegitin zur vollen Öffnung des freien Durclilaßquerschnittes v erfolgensoll. c ist die Kurve der Ouerschnittsänderung, die abweichend von der gezeichneten Kurve auch mit mehreren Knicken verlaufen kann.Fig. I shows a graphic representation of an example of a change in cross-section according to your invention. a is the temperature range within which the transition from the beginning of the opening to the full opening of the free passage cross section v should take place. c is the curve of the cross-section change that deviates from the curve drawn can also run with several kinks.

Die Forderungen des Erfindungsgedanken können erreicht werden bei allen Arten von Drosselorganen, und zwar: i. durch Hinzufügen eines oder mehrerer Zusatzdrosselorgane, z. B. Zusatzschieber. Stufenventile; 2. durch besondere Ausbildung der Steuerkanten des Drosselorgans; 3. durch Zwischenschaltung von Übersetzungen zwischen dem steuernden Thermostaten und dem Drosselorgan; .f. durch Verwendung zweier oder mehrerer Thermostaten, von denen einer nach dem andern seine Steuerarbeit beginnt.The requirements of the inventive concept can be achieved at all types of throttling devices, namely: i. by adding one or more Additional throttle organs, e.g. B. Additional slide. Step valves; 2. through special training the control edges of the throttle member; 3. through the interposition of translations between the controlling thermostat and the throttle device; .f. by using two or more thermostats, one of which after the other does its control work begins.

5. Ferner kann durch Anordnung und Abstimmung von Anpressungsfedern, «-elche auf der Abstromseite liegende Ventile oder Schieber belasten, eine wirksame Beeinflussung im Sinne des Erfindungsgedankens erzielt werden. In Verbindung mit den unter i bis q. aufgeführten Möglichkeiten kann diese Anordnung vorzugsweise dazu dienen. das Zusammenarbeiten der verschiedenen Elemente in gewünschter Weise zu modifizieren.5. Furthermore, by arranging and coordinating contact springs, «-Which load valves or slide valves on the downstream side is an effective one Influence can be achieved in the sense of the inventive concept. Combined with the under i to q. This arrangement can be preferred serve to serve. the cooperation of the different elements in the desired way to modify.

Die unter i bis 5 angeführten :Möglichkeiten können einzeln oder in beliebiger Kombination verwandt werden.The options listed under i to 5 can be used individually or in any combination can be used.
