Sealing system and turbopump comprising such a system

A sealing system for at least one floatingly mounted ring in a support for a rotary shaft rotatable about an axis directed along a longitudinal direction provides dynamic sealing between the shaft and the support. The system includes a coupling part interposed between the ring and the support, where...

Beschreibung
Zusammenfassung:	A sealing system for at least one floatingly mounted ring in a support for a rotary shaft rotatable about an axis directed along a longitudinal direction provides dynamic sealing between the shaft and the support. The system includes a coupling part interposed between the ring and the support, whereby the ring is secured to the support. A first cylindrical type joint directed with respect to a first transverse direction provides a joint between the support and the coupling part. A second cylindrical type joint directed with respect to a second transverse direction perpendicular to the first transverse direction provides a joint between the ring and the coupling part. A turbopump includes such rotary shafts and sealing systems.
