Ie in einer eigenen Arbeitskammer angeordnet sind, die durch gegensinnig wirkende Rückschlagventils alt einer Saug- und einer Förderleitung in Verbindung eteht. Insbesondere bezieht sich die Erfindung auf eine Fördar» und Dosierpumpe zur Förderung von Kraftstoff und Öl für gemisehgeechaierte Brennkraftmaschinen, wobei des Kraftstoffölgeaiseh der Schwimmerkammer eines Vergasers zugeführt wird· Üblicherweise iöt die Kraftstoffpuapa als Meabranpumpe susgebildet» die über ein Pleuel oder einen Stößel angetrieben wird und fördert, wenn die Schwimmernedel des Vergaser« die ZufluOdüse freigegeben hat. Hierbei wird die Membran in Schwingungen vereetzt, die von der Drehzahl der Brennkraftmaschine abhängig sind, wodurch bei einer Kombination einer solchen Kraftstoffpumpe mit einer öldosiarpuaipe die Rückschlagventils in den Saug- und Förderleitungen in ihrer Funktion durch ihre Trägheit beeinträchtigt werden· Dies hat xut Folge, daß ein konstantes Risohungaverhältnis unabhängig von der Fördermenge nicht eingehalten warden kann.Oi * invention relates to a delivery and metering pump for delivering at least two different liquids in a certain quantity ratio, noble the pump two interconnected and executing their suction stroke and their delivery stroke at the same time · displacement body, steicha -J your! Ie are arranged in their own working chamber, which is connected to a suction and a delivery line by means of a non-return valve acting in opposite directions. In particular, the invention relates to a delivery and metering pump for delivering fuel and oil for mixed-use internal combustion engines, whereby the fuel oil is fed to the float chamber of a carburetor when the carburetor float «has released the inlet nozzle. Here, the membrane is vereetzt in vibrations that are dependent on the speed of the internal combustion engine, whereby a öldosiarpuaipe at a combination of such a fuel pump, the check valve in the suction and delivery lines in their function impaired by its inertia · are This has Xut consequence that a constant Risohunga ratio cannot be maintained regardless of the delivery rate.
