Description

Vorrichtung zum Ausläsen eines optischen'Signals bei Überschreitung einer bestimmten Kühlwassertemperatur für Kraftfahrzeugmotoren. Die Erfindung betrifft eine Vorrichtung zum Auslösen eines optischen Signals bei Überschreitung einer bestimmten Kühlwassertemperatur für Kraftfahrzeug notoren. Für diese Zwecke wurden bisher Thermometer verwendet, die unmittelbar auf der Kühlerverschraubung befestigt werden, oder am Armaturenbrett des Motors angeordnete Fernthermometer in Verbindung mit einem im Kühlwasser liegenden Thermostaten, der die Querschnitte der Kühlwasserleitung mittels eines Drehschiebers o. dgl. steuert. Das einfache Thermometer ist vom Führersitz aus schwer zu erkennen, das Fernthermometer in Verbindung mit dem Kühlwasserregler :ist eine kostspielige Einrichtung. Für die weitaus meisten Zwecke genügt es, wenn der Fahrer erkennen kann, ob eine bestimmte Temperatur überschritten wird. Dieses Bedürfnis wird gemäß der Erfindung dadurch befriedigt, daß ein optisches Signal, z. B. ein Fähnchen, das für gewöhnlich in einer Sperrlage gehalten wird, bei Überschreitung der Grenztemperatur niederfällt, indem die Sperrung mittels eines im Kühlwasser liegenden Thermostaten ausgelöst wird'.Device for releasing an optical signal when it is exceeded a certain cooling water temperature for motor vehicle engines. The invention relates to a device for triggering an optical signal when a certain signal is exceeded Cooling water temperature for motor vehicle notors. Thermometers were previously used for this purpose used, which are attached directly to the radiator screw connection, or on the Remote thermometer located on the dashboard of the engine in conjunction with an im Cooling water lying thermostat, which means the cross sections of the cooling water line a rotary valve or the like. Controls. The simple thermometer is from the driver's seat difficult to see, the remote thermometer in connection with the cooling water regulator : is an expensive facility. For the vast majority of purposes it is sufficient if the driver can see whether a certain temperature has been exceeded. This The need is satisfied according to the invention in that an optical signal, z. B. a flag, which is usually kept in a blocked position, when exceeded the limit temperature drops by the blocking by means of an in the cooling water thermostat is triggered '.

Die Zeichnung zeigt die Vorrichtung im Längsschnitt.The drawing shows the device in longitudinal section.

An der Kühlerverschraubung a .ist eine rohrförmige Signalstange b mittels eines Flansches p und einer Mutter q in bekannter Weise befestigt.. Die Stange trägt gemäß der Erfindung am oberen Ende unterhalb -einer Verschlußkuagel o einen Sperrhebel c, der durch eine Feder d in der wagerechten Lage gehalten wird und in dieser durch einen Schlitz e der Sägnalsta:nge b hindurchtritt. Er sperrt in dieser Lage einen Ring f, der mit den Ringen g und h zusammen den Träger für ein Fähnchen i bildet. Der Sperrhebel c ist durch ein im Rohr liegendes Gestänge oder einen Schnurzug k an einen Thermostaten l angeschlossen. Als Thermostat dient eine gewellte Scheibe, die durch einen Spannring in in ihrem Gehäuse n festgehalten wird. Das Gehäuse n wird durch die Mutter q an der Kühlerverschraubung festgeklemmt.At the Kühlerverschraubung a .is a signaling tubular rod b p means of a flange and a nut q in a known manner attached .. The rod supports according to the invention at the upper end below -this Verschlußkuagel o a locking lever c, d by a spring in the balance right Position is held and in this through a slot e of the Sägnalsta: nge b passes. In this position it blocks a ring f which, together with rings g and h, forms the carrier for a flag i. The locking lever c is connected to a thermostat l by means of a linkage or a pull cord k located in the pipe. A wave washer, which is held by a clamping ring in n in its housing serves as a thermostat. The housing n is clamped to the radiator screw connection by the nut q.

Übersteigt die Temperatur des Kühlwassers eine bestimmte obere Grenze, so erfährt der Thermostat l eine so starke Aufwölbung, d!aß durch das Zuggestänge k der Sperrhebel c entgegen der Wirkung der Feder d aus der wagerechten in die schräge Lage herabgezogen wird. Dabei tritt der Hebel c in den Schlitz e der Stange b hinein, so daß der Ring f seine Stütze verliert. Das Fähnchen i fällt daher herab und zeigt dem Führer an, daß das Kühlwasser zu heiß geworden ist.If the temperature of the cooling water exceeds a certain upper limit, the thermostat 1 is bulged so much that the locking lever c is pulled down from the horizontal to the inclined position by the pulling rod k against the action of the spring d. The lever c enters the slot e of the rod b so that the ring f loses its support. The flag i therefore falls and shows the driver that the cooling water has become too hot.
