Claim 0:
1. An internal gear fluid machine comprising:
a first gearwheel having external toothing and 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; and
a filler piece arranged between the first gearwheel and the second gearwheel away from the engagement region, which filler piece bears on a first side against the external toothing and bears on a second 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,
wherein housing walls of a machine housing of the internal gear fluid machine are arranged in an axial direction with respect to the first axis of rotation on both sides of the first gearwheel and the second gearwheel, and
wherein, in order to form a hydrostatic bearing, the second gearwheel is surrounded in a circumferential direction at least in regions by at least one bearing recess which is formed in the machine housing, which bearing recess engages at least partially over 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.
