Abstract
Die Erfindung betrifft eine Exzenterpumpe (1) umfassend ein Gestell (15), eine um eine bezüglich des Gestells (15) ortsfeste Hauptachse (16) drehbar gelagerte, mittels einer Antriebsvorrichtung (73) antreibbare Pumpenwelle (3), eine auf einem Pumpenwellenabschnitt (23) axial verschiebbar gelagerte Exzenterhülse (17), eine zwischen Pumpenwellenabschnitt (23) und Exzenterhülse (17) wirksame Verdrehsicherung (27), mehrere bezüglich des Gestells (15) ortsfest angeordnete Pumpenelemente (5) mit radial zur Hauptachse (16) bewegbaren, auf ein in Hubräumen (8) der Pumpenelemente (5) enthaltenes Fluid einwirkenden Verdrängungselementen (6), die von einer Mantelfläche (18) der Exzenterhülse (17) gegen einen Fluiddruck verschoben werden sowie zumindest ein auf die Exzenterhülse (17) in axialer Richtung wirkendes Federelement (39). Dabei ist der Pumpenwellenabschnitt (23) als schräger Exzenterzapfen (24) mit einer zur Hauptachse (16) in einem Schrägungswinkel (26) verlaufenden Exzenterzapfenachse (25) ausgebildet und die auf dem Exzenterzapfen (24) geführte Exzenterhülse (17) weist eine zylindrische Mantelfläche (18) auf, deren Erzeugenden (20) parallel zur Hauptachse (16) verlaufen.
