Abstract
Description
Die Erfindung betrifft eine Flüssigkeitspumpe mit regelbarem Fördervolumen, gemäß dem Oberbegriff des Anspruchs 1.The The invention relates to a liquid pump with adjustable delivery volume, according to the generic term of claim 1.
Eine
gattungsgemäße Flüssigkeitspumpe
ist aus der DE
Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Flüssigkeitspumpe derart weiterzuentwickeln, dass bei verminderter Geräuschentwicklung deren Lebensdauer verbessert ist.Of the Invention is based on the object, a generic liquid pump to develop such that with reduced noise whose life is improved.
Diese Aufgabe wird mit einer Flüssigkeitspumpe gemäß dem Anspruch 1 gelöst.These Task is with a liquid pump according to the claim 1 solved.
Durch die erfindungsgemäße Vorspannung des Verstellkolbens in Richtung einer Drehung um seine Achse werden rotatorische Wechselbeanspruchungen des Verstellkolbens vermindert, insbesondere überkompensiert, so dass die Anlagefläche des Verstellkolbens sich ständig in wohl definierter Anlage an der Gegenfläche des Gehäuses befindet.By the bias of the invention Be adjusting piston in the direction of rotation about its axis reduced rotational stresses on the adjusting piston, especially overcompensated, so that the contact surface the adjusting piston constantly located in well-defined system on the opposite surface of the housing.
Die Unteransprüche sind auf vorteilhafte Weiterbildungen der erfindungsgemäßen Flüssigkeitspumpe gerichtet, die gemäß dem Anspruch 5 vorteilhafter Weise als Ölpumpe einer Brennkraftmaschine ausgebildet ist.The under claims are on advantageous developments of the liquid pump according to the invention directed according to the claim 5 advantageously as an oil pump an internal combustion engine is formed.
Die Erfindung wird im Folgenden anhand schematischer Zeichnungen beispielsweise und mit weiteren Einzelheiten erläutert.The Invention will be described below with reference to schematic drawings, for example and explained in more detail.
