Abstract

See full text

An internal gear fluid machine includes a first gearwheel having an external toothing and mounted rotatably about a first axis of rotation, and a second gearwheel having an 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. The internal gear fluid machine additionally includes a filler piece arranged between the first gearwheel and the second gearwheel away from the engagement region, which filler piece bears on 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. Sealing discs are arranged in the axial direction with respect to the first axis of rotation on both sides of the first gearwheel and the second gearwheel, which, during operation of the internal gear fluid machine, bear in a sealing manner against the first gearwheel and the second gearwheel, and an axial opening is formed in each of the sealing discs. A common one of the fluid chambers is in flow communication with the same fluid connection of the internal gear fluid machine via both axial openings.
