Abstract
An internal-gear machine has a casing and a running assembly accommodated in the casing and comprising a rotatably mounted pinion and an internally toothed annular gear meshing with the pinion. The annular gear is widened at its outer periphery to form a running ring which can be integral with the internally toothed part of the annular gear or a separately produced component which is non-rotatably connected to the internally toothed part.
