Description

Vorrichtung zur Änderung des Zusammensetzungsverhältnisses eines Strömungsgemisches in Abhängigkeit von einer Temperatur Die Erfindung betrifft eine Vorrichtung, durch welche die Zusammensetzung eines Strömungsgemisches in Abhängigkeit von einer Außentemperatur beeinflußt werden soll. Um eine solche Vorrichtung insbesondere zur Überwachung der Zuführung von Zusatzluft zu Vergasern in Abhängigkeit von der Temperatur der Augenluft oder einer vom Betrieb des Motors abhängenden Temperatur verwenden zu können, liegt gemäß der Erfindung in einem Körper, der bei der Beeinflussungstemperatur flüssig wird, ein Kolben, welcher mit einem dem Zufluß des Strömungsmittels (z. B. der Zusatzluft) beherrschenden Absperrventil verbunden ist.Device for changing the composition ratio of a flow mixture as a function of a temperature The invention relates to a device by which is the composition of a flow mixture as a function of an outside temperature should be influenced. To such a device in particular for monitoring the supply of additional air to the carburetors depending on the temperature of the Use eye air or a temperature that depends on the operation of the engine can, according to the invention in a body that is at the influencing temperature becomes liquid, a piston which is connected to the inflow of the fluid (e.g. B. the additional air) dominant shut-off valve is connected.

Die Zeichnung stellt schematisch im lotrechten Schnitt als Beispiel eine Vergasungsvorrichtung gemäß der Erfindung dar.The drawing represents schematically in vertical section as an example represents a gasification device according to the invention.

Der Vergaser ist durch die Spritzdüse e und das Gemischrohr f angedeutet. An dieses schließt die Zusatzluftleitung g an, deren Eintritt durch das federbelastete Ventil )a beherrscht wird, das durch eine Stangei mit dem Kolben j eines Behälters k verbunden ist. Die Flüssigkeit :b in diesem Behälter, in welche der Kolben j taucht, ändert ihre Zähigkeit mit den praktisch vorkommenden Temperaturen zwischen dem festen und dem flüssigen Zustand. Die Wärmebeeinflussung des Behälters k kann in beliebiger Weise, z. B. durch die Lufttemperatur, durch Auspuffgase, durch Kühlwasser oder Ölumlauf o. dgl., erfolgen.The carburetor is indicated by the spray nozzle e and the mixture pipe f. This is followed by the additional air line g, the entry of which is controlled by the spring-loaded valve) a, which is connected by a rod to the piston j of a container k . The liquid: b in this container, into which the piston j is immersed, changes its viscosity with the practically occurring temperatures between the solid and the liquid state. The heat influence of the container k can be in any way, for. B. by the air temperature, by exhaust gases, by cooling water or oil circulation o.

Bei richtiger Wahl des Zustandes der Flüssigkeit und der ihre Temperatur beeinflussenden Mittel läßt sich erreichen, daß das Ventil h, welches beim Stillsetzen des Motors durch seine Feder auf seinen Sitz gedrückt wird, ohne hieran von der dann noch warmen Flüssigkeit gehindert zu werden, in dieser Stellung festgehalten wird, wenn die Temperatur im Behälter k so weit gesunken und die Flüssigkeit b so weit erstarrt ist, das sie jede Bewegung des Kolbens j verhindert. In diesem dem kalten Zustand des Motors ist die Zuführung von Zusatzluft zum Vergaser f unerwünscht. Wird nun der Motor bei Wiederinbetriebsetzenallmählich wärmer, so geht der fest gewordene Inhalt b des Behälters k allmählich wieder in den flüssigen Zustand über und gibt damit den Kolben j und das Ventil l: frei, welches nun durch den Unterdruck im Saugrohr f geöffnet wird.With the correct choice of the condition of the liquid and its temperature influencing means can be achieved that the valve h, which when stopped of the motor is pressed onto its seat by its spring, without being affected by the then to be prevented from still warm liquid, held in this position becomes, when the temperature in the container k has dropped so far and the liquid b so is far frozen that it prevents any movement of the piston j. In this that When the engine is cold, the supply of additional air to the carburetor is undesirable. If the engine gradually warms up when it is restarted, it stalls the contents b of the container k gradually return to the liquid state and thus releases piston j and valve l: which is now due to the negative pressure is opened in the suction pipe f.
