Abstract:
1. A bearing chamber including a vent, the vent including a vortex diode defining a chamber having a central axis and a peripheral wall surrounding said central axis, said peripheral wall including a conduit, said chamber defining a first flow path and a second flow path, in which fluid is able to flow through the chamber along either the first flow path or the second flow path, in which the resistance to fluid flow is relatively high when the fluid follows the first flow path and the resistance to fluid flow is relatively low when the fluid follows the second flow path wherein a wall is provided and spaced inwardly of said peripheral wall to provide an axially extended chamber by said peripheral wall to receive a higher density component separated from the fluid and for passing the higher density component back to the bearing chamber through said conduit.
