Abstract

Le dispositif selon la présente invention comprend un générateur de pression 23 qui porte une fraction du liquide envoyé au palier 1, 2, 3, 4 à une pression supérieure à la pression maximale dans le palier, cette fraction communiquant avec un accumulateur 18, une partie de cette fraction étant dirigée sur le palier, à travers une ou plusieurs valves 24, 25, 26 à écoulement constant, et le restant étant dirigé jusqu'à un point 27 où règne une pression inférieure, cela à travers une valve 28 adaptée de manière à s'ouvrir quand la pression du liquide atteint ladite pression supérieure.The device according to the present invention comprises a pressure generator 23 which brings a fraction of the liquid sent to the bearing 1, 2, 3, 4 at a pressure greater than the maximum pressure in the bearing, this fraction communicating with an accumulator 18, a part of this fraction being directed onto the bearing, through one or more valves 24, 25, 26 with constant flow, and the remainder being directed to a point 27 where there is a lower pressure, this through a valve 28 adapted in such a way to open when the pressure of the liquid reaches said higher pressure.
