Abstract
An internal geared machine capable of forward and reverse operation in a closed circuit having a pinion and an internal toothed ring gear meshing with the pinion and disposed in a housing. A filling comprising two identical filler pieces fills a sickle-shaped space between the pinion and ring gear and a single stop pin mounted in the housing supports both of the filler pieces by their front ends. A pair of axial discs are seated on the pinion shaft on respective sides of the pinion and axial pressure fields and control fields provide opposing pressures against the axial discs.
