Abstract

The radial sealing ring in hydraulic machines consists of a ring packing (5) and support ring (10), each with disc-form sections (7,11). The disc-form section (11) of the support ring has a cross sectional contour effecting stiffening and is curved out or elbowed out from a plane extending perpendicularly to the middle axis of the radial sealing ring. The disc-form sections of the ring packing and support ring have a constant wall thickness in their cross sectional extent. An independent claim is included for an axial piston machine with the proposed radial sealing rings for the sealing of rotating shafts in relation to stationary casing sections.
