The object of the invention is a rotator, which includes an axle (8) and an associated rotor component (1) with lamellar wings (2), a case component (3) surrounding this, chambers (7) lying between them arranged symmetrically in relation to the axle, pressurized oil feed and outlet openings connected to the chambers bearing members (9, 10) in an axial direction on both sides of the rotor component (1). This includes a pressure bearing (10) beneath that carrying the axial load i.e. the rotor. The pressure bearing (10) is composed of a conical arrangement (11), 12) between the case (3) and the axle (8). The case (3) includes channels (19) leading from the chambers (7) to the lower surface of the conical arrangement (11, 12). The upper and lower parts of the conical arrangement (10) include gaskets (13, 14). The conical arrangement (10) is dimensioned in such a way that the pressure acting on the conical surfaces raises the axle (8) off the case (3) and when without pressure the conical arrangement forms a friction lock.

Ce rotateur comporte un axe (8) auquel est associé un élément rotor (1) muni d'ailettes lamelliformes (2), d'un élément carter (3) renfermant l'ensemble, de chambres (7) intermédiaires disposées symétriquement par rapport à l'axe, d'ouvertures pratiquées dans les chambres pour l'admission et l'évacuation de l'huile sous pression, d'éléments paliers (9, 10) situés des deux côtés de l'élément rotor (1) par rapport au sens de l'axe. Ce dispositif comporte un palier pressurisé (10) placé sous le palier supportant la charge de l'axe, c'est-à-dire le rotor. Le palier pressurisé se compose d'un organe conique (11, 12) situé entre le carter (3) et l'axe (8). Le carter (3) est muni de canaux (19) partant des chambres (7) et aboutissant à la surface inférieure de l'organe conique (11, 12). Les parties supérieures et inférieures de l'organe conique (10) sont munies de joints (13, 14). L'organe conique est dimensionné de façon que la pression s'exerçant sur les surfaces coniques relève l'axe (8) pour le dégager du carter (3) et le font retomber en position freinée (du fait de la friction) lorsque la pression cesse de s'exercer.
