Abstract
A rotary machine includes a fixed internal body, a rotating external body and a lubrication system to lubricate one or more components of the internal body or external body during rotation. The lubrication system includes: an inlet conduit for a lubricant, formed in the internal body; one or more distribution conduits for the lubricant; a lubricant collection chamber between the external body and the internal body; and an outlet conduit communicating with the collection chamber.

1-17. (canceled)
A rotary machine comprising:
- an internal body extending about a main rotation axis of said rotary machine, said internal body being fixed with respect to said main rotation axis,
- an external body rotatably supported in a radially external position about said internal body, said external body being configured to be rotated about said main rotation axis, and
- a lubrication system configured to lubricate at least one component of said internal body or said external body during rotation of said external body about said internal body, said lubrication system comprising:
- an inlet conduit for a lubricant, said inlet conduit being formed in said internal body and being configured to conduct the lubricant inside said rotary machine,
- at least one distribution conduit for the lubricant, said at least one distribution conduit being configured to conduct the lubricant from said inlet conduit to said at least one component,
- a lubricant collection chamber between said external body and said internal body and configured to collect the lubricant downstream of said at least one component, and
- an outlet conduit communicating with said collection chamber, the outlet conduit being formed in said internal body and being configured to conduct the lubricant outside said rotary machine.
A method for lubricating a rotary machine comprising a fixed internal body and an external body configured to rotate about a main rotation axis of said rotary machine, said method comprising:
- introducing a lubricant into said rotary machine through an inlet conduit formed in said internal body,
- distributing said lubricant through a distribution conduit,
- collecting said lubricant in a collection chamber defined between said internal body and said external body, and
- discharging the lubricant from said rotary machine through an outlet conduit formed in said internal body and communicating with said collection chamber.
