ABSTRACT:
A rotary and sealed connection for pressurized fluids is provided, including a first part that is secured, for example, to a fixed source of pressurized fluid and has a recess for communication therewith and through a second part, with a fluid-using rotary apparatus of revolution rotating about a shaft and extending through the first part through a passage, said second part having a degree of radial freedom and being held in position without play by a seal serving as a bearing. The annular space in the passage may thus be extremely reduced, thus avoiding any risk of extrusion of the seal.
