Abstract: A vane cell machine includes a housing, rotor, curved ring, spring, and pressure piece. The rotor is configured to rotate about a rotation axis and includes a plurality of plate-like wings that are radially displaceable. The curved ring surrounds the rotor and delimits a movement path of the wings. Each pair of adjacent plate-like wings delimits a corresponding operating chamber. The housing surrounds and enables displacement of the curved ring. The spring is positioned between the curved ring and the housing, is pretensioned, and is configured to load the curved ring. The pressure piece is positioned between the spring and the curved ring, and sealingly abuts the housing and the curved ring so as to delimit a first and second pressure chamber from each other. The housing and the curved ring further delimit the first and second pressure chambers.

Abstract: A bearing element for a sliding bearing is configured to support a drive shaft of a hydraulic machine. The bearing element is connected to the drive shaft so as to prevent relative rotation and has an outer annular surface configured to provide sliding support. A supporting web is formed between a location at which the bearing element is fixed to the drive shaft and the outer annular surface. The supporting web is elastically deformable to compensate for deflection of the drive shaft and/or an alignment error of sliding bearings of the drive shaft. A sliding bearing has a bearing element of this kind, and a hydraulic machine has at least one sliding bearing of this kind.
