    摘要: The invention relates to a rotor of a non-positive-displacement machine which, when exposed, has an inspection area which is visible from the outside and inside of which a comparatively uncritical load occurs during the operation of the non-positive-displacement machine. In addition, the rotor, when exposed, has a monitoring area which is not visible from the outside and inside of which a comparatively critical load occurs during the operation of the non-positive-displacement machine. The rotor also has a weak point provided in the form of a predetermined breaking point having the shape of a notch and located in inspection area. In order to improve the reliability of the non-positive-displacement machine, a recess, particularly a release bore hole, is provided for delimiting the weak point, and the uncritical defect can terminate inside said release bore hole.
