Abstract

Die Anmeldung betrifft eine hydrostatische Verdrängermaschine mit einem ersten und einem zweiten drehbaren Zahnrad (10), welche ineinander eingreifen, wobei sie von einem Gehäuse mit einem ersten und einem zweiten Fluidanschluss derart umgeben sind, dass eine Drehbewegung der Zahnräder mit einem Fluidstrom zwischen dem ersten und dem zweiten Fluidanschluss einhergeht, wobei die Form der Zahnflanken (14) des ersten und des zweiten Zahnrades (10) so ausgebildet sind, dass sich deren Kontaktpunkt bei deren Drehung entlang einer Eingriffslinie bewegt, die gekrümmt verläuft und wobei die Flankenlinie (15) des ersten und/oder des zweiten Zahnrades (10) von der Geraden abweicht.
