Abstract (en)
[origin: DE102005004657A1] The machine has a sealing disk arranged between side surfaces of gear wheels and a housing part and pressed on a pressure field at the surfaces. A gap between the part and disk runs out from the field. A seal (64) is supported on its side facing the gap by a support ring (71). The ring is arranged with a support bar (75) that supports the seal in a form-fit manner, inwardly intervenes with the seal and extends in an axial direction.
