Abstract: An epicyclic reduction gear, for example for a turbomachine, including a device forming a fluid circulation passage configured to generate a pressure drop, created by stacking at least two elements. Each element includes a passage for carrying fluid configured to generate a pressure drop and including an inlet and an outlet. The outlet, or inlet, of the passage of one of the elements is, respectively, connected to the inlet, or to the outlet, of the passage of the other element.

Abstract: The invention concerns a planet carrier (5) for an epicyclic speed reduction gear, comprising an annular cage (7) comprising two sides (9, 10) extending radially, linked by bridges (16), seats (6) extending axially between the sides (9, 10) and being intended to support planet gears mounted rotating about the seats (6). One (9) of the sides (9, 10) of the cage (7) is immovably fixed to a torque output member (8), in such a way as to form a single structural assembly.
