SEALING SYSTEM AND TURBOPUMP CONTAINING SUCH SYSTEM Russian patent published in 2019 - IPC F16J15/44 

FIELD: engines and pumps.

SUBSTANCE: invention relates to a sealing system for at least one ring (40, 40A–40C) floating in support (10, 10A–10C) for rotating shaft (20, 20A–20C) that can rotate around an axis directed in the longitudinal directions (Z) in order to provide a dynamic seal between shaft (20, 20A–20C) and support (10, 10A–10C). Additionally, the system contains coupling part (60, 60A–60C) interposed between ring (40, 40A–40C) and support (10, 10A–0C), through which ring (40, 40A–40C) is attached to support (10, 10A–10C). Also the first connection of a cylindrical type directed relative to the first transverse direction provides a connection between support (10, 10A–10C) and coupling part (60, 60A–60C). Further, the second connection of a cylindrical type directed relative to the second transverse direction that is perpendicular to the first transverse direction provides a connection between ring (40, 40A–40C) and coupling part (60, 60A–60C). Also the invention provides a turbopump containing such rotating shafts (20, 20A–20C) and sealing systems.

EFFECT: proposed are a sealing system and a turbopump containing such a system.
