    摘要: A fluid damping structure is provided that includes a damper ring. The damper ring includes an annular body, a plurality of fluid check valves (122), and at least one fluid stop (124). The annular body extends circumferentially around an axial centerline, and is defined by a first end surface (88), a second end surface (90), an outer radial surface (92), and an inner radial surface (94). The outer radial surface (92) and the inner radial surface (94) extend axially from the first end surface (88) toward the second end surface (90). The body includes one or more check valve passages (104). Each check valve passage (104) extends axially from an open end (106) disposed at the first end surface (88) inwardly toward the second end surface (90), and is disposed between the inner radial surface (94) and the outer radial surface (92). An inlet aperture (112) extends between each check valve passage (104) and the outer radial surface (92), and an outlet aperture (114) extends between each check valve passage (104) and the inner radial surface (94). Each fluid check valve (122) is disposed in a check valve passage (104). The at least one fluid stop (124) is configured to prevent fluid exit from the open end (106) of each check valve passage (104).

    摘要: An oil transfer unit (1) feeds oil into a moving, rotating tube (2) extending along an axis (5); the unit (1) is provided with a support plate (11) transversal to the axis (11) and a sleeve (28), which is angularly fixed with respect to the support plate (11), it is configured to be coupled in a sliding and watertight way to a terminal section of the inlet (20) of said tube (2) and has at least one chamber (32, 33) for transferring oil into said terminal section of the inlet (20); the unit is also equipped with at least two tubular bodies (29, 30, 31), which project axially from the support plate (11), define between them an annular channel (37,38) communicating with the chamber (32,33) and join the sleeve (28) to the support plate (11) in a watertight manner and with clearances so as to leave freedom of orientation of the sleeve (28) around any direction orthogonal to the axis (5).

    摘要: L'invention concerne un réservoir (30) d'huile équipant une turbomachine, notamment un turboréacteur d'avion. Le réservoir (30) comprend une chambre intérieure (36) contenant l'huile de la turbomachine ; une paroi (42) avec une surface interne (40) entourant la chambre intérieure (36); et un dispositif capacitif de mesure de niveau d'huile. Le dispositif comprend au moins une électrode (38), éventuellement deux électrodes (38) parallèles formant la surface interne (40). Ces électrodes (38) baignent dans l'huile pour en mesurer le niveau en effectuant une mesure de capacité électrique. L'invention propose également procédé de réalisation d'un réservoir (3) où les électrodes (30) sont imprimées contre la paroi (42).

    摘要: A transfer coupling comprises a static component (41) and a rotatable component (42) arranged in co-axial alignment. The static component (41) includes a first number of ports (41 a) and the rotatable component (42) includes a second number of ports (42a). The ports are arranged in a common circumferential plane and are configured and arranged, in use, to homogenise a flow area for a fluid being transferred through the ports (41 a, 42a) and thereby create a homogenous volume flow. The packing factor of ports on at least one of the components is at least 40%.
