Description
Vorrichtung zur Zuführung des Erennstoff & zum Vergaser von Brennkraftmaschinen Es ist bekannt, den Vergaser von Brennkraftmaschinen aus einem oberhalb des Vergasers liegenden Hilfsbehälter zu speisen, der init einem Schwimmer ausgestattet ist, um in diesem Hilfsgefäß dauernd einen bestimmten Flüssigkeitsstand aufrechtzuerhalten und damit die Gefällshöhe des Brennstoffes -leichzuhalten. Das Hilfsgefäß wird seinerseits durch eine Pumpe gespeist, die den Brennstoff aus den Hauptbrennstoffbehälter ansau 'gt. Die Speiseleitung der Pumpe wird durch den Schwimmer abgesperrt, wenn die Förderung der Pumpe einen bestimmten Flüssigkeitsstand. im Hilfsbehälter überschreitet. Als Pumpe wird in der Regel eine Xlembranpumpe verwendet, die leer weiterarbeiten kann, wenn die Speiseleitung abgesperrt ist.Device for supplying fuel & to the carburetor of internal combustion engines It is known to feed the carburetor of internal combustion engines from an auxiliary container located above the carburetor, which is equipped with a float in order to maintain a certain liquid level in this auxiliary container and thus the gradient of the fuel -to keep the same. The auxiliary vessel is in turn fed by a pump which sucks the fuel from the main fuel container. The feed line of the pump is shut off by the float when the pump is conveying a certain liquid level. in the auxiliary tank exceeds. A membrane pump is usually used as the pump, which can continue to work empty when the feed line is shut off.
Bei den bisher bekannten Hilfsgefäßen ,vurde die Absperrung der Pumpenspeiseleitung durch ein Nadelveritil bewirkt. Es hat sich nun gezeigt, daß der Auftrieb des Schwimmers nicht ausreicht, um einen dichten Abschluß der Speiseleitung durch das Nadelventil zu erreichen.In the previously known auxiliary vessels, the pump feed line was shut off caused by a Nadelveritil. It has now been shown that the buoyancy of the swimmer is not sufficient to seal the feed line tightly through the needle valve to reach.
Um ein Überlaufen des Brennstoffbehälters zu verhindern, muß an die Speiseleitung eine Überlaufleitung angeschlossen werden, um den zu viel geförderten Brennstoff in den Hauptbehälter zurückzuführen.To prevent the fuel tank from overflowing, the Feed line an overflow line can be connected to the overflow Return fuel to the main tank.
Dieser Nachteil wird gemäß der Erfindung dadurch beseitigt, daß die Absperrung der das Hilfsgefäß speisenden Pumpenleitung durch einen Rohrschieber erfolgt.This disadvantage is eliminated according to the invention in that the Blocking of the pump line feeding the auxiliary vessel by a pipe valve he follows.
Auf der Zeichnung ist ein Ausführungsbeispiel einer Vorrichtung nach der Erfindung schematisch im Schnitt dargestellt.In the drawing is an embodiment of a device according to the invention shown schematically in section.
Der oberhalb des Vergasers angeordnete Hilfsbehälter a ist durch einen Deckel h abgeschlossen, der mit einem Röhrchen i versehen ist, uni den Innenraum des Gefäßes a unter den äußeren Luftdruck- zu setzen. In den Behältera mündet die von der Pumpe kommende Leitungf ein, die innerhalb des Hilfsbehälters in ein unten geschlossenc-s, senkrecht stehendes Rohr c ausläuft. Das Rohr c wird zweckmäßig mit dem Boden des Behälters fest verbunden. In dem Boden des Behälters ist die züm Vergaser führende Abflußleitungg angeordnet. Das Rohrc ist mit seitlichen Ausströmöffnungen e versehen, die durch einen Rohrschieberd beherrscht werden. Zur Bewegung des Rohrschiebers d dient der mit ihm verbundene Schwimmer b. The auxiliary container a, which is arranged above the gasifier, is closed by a cover h which is provided with a small tube i to put the interior of the vessel a under the external air pressure. The conduit f coming from the pump flows into the container a, which ends inside the auxiliary container in a tube c which is closed at the bottom c-s and is vertical. The tube c is expediently firmly connected to the bottom of the container. The discharge line leading to the carburetor is arranged in the bottom of the container. The pipe c is provided with lateral outflow openings e, which are dominated by a pipe slide valve. The float b connected to it is used to move the pipe slide d.
Der durch das Rohr f gefördertc Brennstoff fließt durch die Öffnungen e in den Behälter a. Mit steigendem Schwimmer werden die Öffnungen durch den Schieber (1 allmih- - ]ich abgedeckt.The fuel conveyed through the pipe f flows through the openings e into the container a. As the float rises, the openings are covered by the slide (1 gradually - ] i.
