The invention relates to a rotor element (3) that comprising an annular surface portion about the rotor rotational axis, a fluid passage (31) being formed through said surface portion, characterised in that it comprises a passage-blocking means (31), said means including a blocking element (4) that is deformable depending on the rotor rotating speed and arranged so as to adjust the fluid flow depending on the rotor rotating speed, and an annular collar (6) with a free edge (62) engaging with said blocking element (4) so as to form said blocking means, wherein the free edge (62) of the annular collar (6) defines, together with the blocking portion (43) of the blocking element (4), a diaphragm that blocks the fluid passage (31).
Un élément de rotor (3) comportant une portion de surface annulaire autour de l'axe de rotation du rotor, un passage de fluide (31) étant ménagé à travers ladite portion de surface, caractérisé par le fait qu'il comporte un moyen d'obturation dudit passage(31), ledit moyen comprenant un élément (4) d'obturation, déformable en fonction de la vitesse de rotation du rotor,agencé pour réguler le débit de fluide en fonction de la vitesse de rotation du rotor et une virole annulaire (6) avec un bord libre (62) coopérant avec ledit élément d'obturation (4) pour former ledit moyen d'obturation, le bord libre (62) de la virole annulaire (6) formant avec la partie d'obturation (43) de l'élément d'obturation (4) un diaphragme obturant le passage de fluide (31).
