Abstract
An internal gear fluid machine has a first gearwheel having external toothing mounted rotatably about a first axis of rotation and a second gearwheel having internal toothing meshing in regions with the external toothing in an engagement region and mounted rotatably about a second axis of rotation different from the first axis of rotation. A filler piece is arranged between the first gearwheel and the second gearwheel away from the meshing region which bears on the one side against the external toothing and on the other side against the internal toothing, in order to divide a fluid space present between the first gearwheel and the second gearwheel into a first fluid chamber and a second fluid chamber, and housing walls of a machine housing of the internal gear fluid machine being arranged in the axial direction with respect to the first axis of rotation on both sides of the first gearwheel and of the second gearwheel. The second gearwheel is surrounded in the circumferential direction to form a hydrostatic bearing by a bearing recess formed in the machine housing, which bearing recess at least partially overlaps the second gearwheel in the axial direction and is fluidically connected to a fluid connection of the internal gear fluid machine via a fluid line having a flow resistance.
