Description

Spritzvergaser 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 carburetors It has already been proposed to attach needle valves to the carburetors and they through a thermostat different from that of the engine draining cooling water is washed around to control. Such thermostats are also allowed act directly on the valve needle. After all, you already have them 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. Von besonderer Bedeutung ist, daß das Gestänge für die Ventilnadel durch eine Membran unterteilt ist, welche dazu dienen soll, den Brennstoffraum vollkommen von dem den Thermostaten bildenden Raum zu trennen, wodurch ein Übertreten von Quecksilber in den Brennstoff und damit auch eine unbeabsichtigte Verstellung der Regelung durch Quecksilberverluste vermieden werden soll.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. Of special It is important that the linkage for the valve needle is divided by a membrane is, which should serve to completely separate the fuel compartment from that of the thermostat separating the forming space, thus preventing mercury from entering the fuel and thus also an unintentional adjustment of the regulation due to mercury losses should be avoided.

In der Zeichnung ist eine Ausführungsform der Erfindung dargestellt.In the drawing, an embodiment of the invention is shown.

An dem Vergasergehäuse a ist unterhalb der Spritzdüse b eine Kappe c angeschraubt, deren Innenraum d durch eine Membran e vollkommen von dem Brennstoffraum vor der Spritzdfise b getrennt wird. Die Membran ist unter Zwischenfügung eines Dichtungsringes g zwischen die Kappe c und das Vergasergehäuse a geklemmt. Die Kappe c besitzt zwei Rohranschlüsse lt und i, welche zur Zuleitung bzw. zur Ableitung des Kühlwassers dienen. Unterhalb der Membran eist im Gehäuse c das Ouecksilbergefäß k vorgesehen, welches von dem durchströmenden Kühlwasser umspült wird. Der Quecksilberinnenraum kann durch eine Verdrängerschraube q mit Sicherheitsring verkleinert oder vergrößert werden. Die Kappe c ist mit einem Verschlußdeckel p versehen. Der obere Teil des Quecksilbergefäßes k ist zylindrisch und enthält einen sauber eingeschliffenen Kolben l., der auf der Oberfläche des Quecksilbers ruht. An dem Kolben L ist ein mit Gewinde und Gegenmutter versehener Stößel m angebracht, der sich in der Richtung zur Düsenöffnung auf die Membran aufstößt. Hinter der Membran ist ein -gleichfalls mit Gewinde versehener Stößel angebracht, dessen Verlängerung die Ventilnadel bildet. Zwischen Düse b und dem Stößel zi ist eine Feder o eingelegt, die den Stößel n gegen die Membran e bzw. den Stößel m aufsetzt.On the carburetor housing a there is a cap below the spray nozzle b c screwed on, the interior d of which is completely separated from the fuel chamber by a membrane e before the Spritzdfise b is separated. The membrane is with the interposition of a Sealing ring g clamped between the cap c and the carburetor housing a. The cap c has two pipe connections lt and i, which are for supply and discharge serve the cooling water. The mercury vessel is located in the housing c below the membrane k is provided, which is washed around by the cooling water flowing through. The mercury interior can be reduced or enlarged using a displacement screw q with a safety ring will. The cap c is provided with a closure cap p. The upper part of the The mercury vessel k is cylindrical and contains a neatly ground piston l. resting on the surface of the mercury. On the piston L is a threaded one and lock nut fitted plunger m attached, which extends in the direction of the nozzle opening abuts the membrane. Behind the membrane there is also a threaded one Plunger attached, the extension of which forms the valve needle. Between nozzle b and A spring o is inserted into the plunger zi, which pushes the plunger n against the membrane e or touches the ram m.
