Abstract
The invention relates to an internal gear machine (10) having a housing (12) which forms a cavity (14) in which an internally toothed ring gear (18) and an externally toothed pinion (16) are arranged, the toothings (24, 26) of which are in meshing engagement with one another in certain regions and the axes of rotation (20, 22) of which run parallel to and spaced apart from one another, wherein at least one filler piece (30, 30′) rests against the first and second toothings (24, 26), which divides the cavity (14) into two fluidically separate regions. It is provided that the toothing (24, 26) is designed as helical toothing or arrow toothing.
