Description

Spritzvergaser mit von einem Thermostaten verstelltem Nadelventil ' Es ist bereits vorgeschlagen worden, Nadelventile an den Vergasern anzubringen und sie durch einen Thermostaten, der von dem vom Motor abfließenden Kühlwasser umspült wird, zu steuern. Man läßt auch derartige Thermostaten unmittelbar auf die Ventilnadel einwirken. Schließlich hat man auch bereits die Wärmeausdehnung von Quecksilber für diesen Zweck benutzt, welches einen Kolben bewegt.Injection carburetor with a needle valve adjusted by a thermostat It has already been proposed to attach needle valves to the carburetors and through a thermostat, which is controlled by the cooling water drained from the engine is washed around to control. You can also such thermostats directly on the Act on valve needle. After all, you already have the thermal expansion of Mercury used for this purpose, which moves a piston.

Die Erfindung besteht in der besonderen im Anspruch gekennzeichneten Bauart einer solchen Thermostatenvorrichtung, die zum leichten Anbau an einen Vergaser geeignet und den Betriebsbedingungen entsprechend einstellbar ist.The invention consists in the particular one characterized in the claim Design of such a thermostat device, which can be easily attached to a carburetor suitable and adjustable according to the operating conditions.

In der Zeichnung ist eine Ausführungsform der Erfindung in einem Längsschnitt dargestellt.In the drawing, an embodiment of the invention is in a longitudinal section shown.

Am Vergasergehäuse a ist unterhalb der Spritzdüse b eine Kappe c angeschraubt, deren Innenraum d durch eine dünne elastische Platte e gegenüber dein Brennstoff f abgesperrt ist. Die Platte e ist unter Zwischenfügung eines Dichtungsringes g an der Kappe c befestigt. Die Kappe c besitzt zwei Rohranschlüsse h und i, welche zur Zuleitung bzw. Ableitung des Kühlwassers dienen. Ah der Platte e ist das Quecksilbergefäß k derart befestigt, daß es frei im Innern der Kappe c hängt und vollständig von dem durch die Kappe hindurchströmenden Kühlwasser umspült wird. Der obere Teil des Quecksilbergefäßes k ist zylindrisch und enthält einen genau eingeschliffenen Kolben 1, der auf der Oberfläche des Quecksilbers ruht. An dem Kolben Z ist die Ventilnadel m befestigt, die durch eine Stopfbüchse za dn der Platte e hindurch- und in die Spritzdüse b hineinragt. Zwischen der Platte e und dem Kolben Z befindet sich eine Schraubenfeder o.A cap c is screwed onto the carburetor housing a below the spray nozzle b, the interior d of which is blocked off from your fuel f by a thin elastic plate e. The plate e is attached to the cap c with the interposition of a sealing ring g. The cap c has two pipe connections h and i, which are used to supply and discharge the cooling water. The mercury vessel k is attached to the plate e in such a way that it hangs freely in the interior of the cap c and is completely surrounded by the cooling water flowing through the cap. The upper part of the mercury vessel k is cylindrical and contains a precisely ground piston 1, which rests on the surface of the mercury. The valve needle m is attached to the piston Z and projects through a stuffing box za dn of the plate e and into the spray nozzle b. Between the plate e and the piston Z there is a helical spring o.

Die Wirkungsweise der Einrichtung ist aus der Zeichnung ohne weiteres verständlich. Das Quecksilber dehnt sich entsprechend der Temperatur des Kühlwassers aus und hebt den Kolben mit der Nadel, welche den Querschnitt der Spritzdüse entsprechend verengt. Bei Abnahme der Wassertemperatur und Sinken des Quecksilberspiegels sorgt die Feder o für die Abwärtsbewegung des Kolbens 1.The operation of the device is clear from the drawing understandable. The mercury expands according to the temperature of the cooling water and lifts the piston with the needle, which corresponds to the cross-section of the spray nozzle narrowed. When the water temperature drops and the mercury level drops, it takes care of it the spring o for the downward movement of the piston 1.

Durch eine Schraube p, die im Boden der Kappe c sitzt und gegen den Boden des Quecksilbergefäßes k drückt, kann man unter Ausnutzung der Elastizität der Platte e die Vorrichtung von außen her in bequemer Weise genau einstellen.By a screw p, which sits in the bottom of the cap c and against the Pressing the bottom of the mercury vessel k, one can make use of the elasticity the plate e adjust the device from the outside in a convenient way.
