1. An assembly comprising:
a first rotating component; a second rotating component disposed adjacent to said first rotating component, said first and second rotating component concentrically aligned along an axial centerline, wherein said first rotating component is engaged with said second rotating component along a frictional interface, said frictional interface defined radially outwardly from said axial centerline; a high pressure cavity defined between said first and second rotating components, wherein said high pressure cavity is defined proximate to said axial centerline; a low pressure cavity defined between said first and second rotating components radially outwardly from said high pressure cavity and radially inwardly from said frictional interface with respect to said axial centerline; an annular slot defined between said first and second rotating components, said annular slot being defined between said high pressure and low pressure cavities, said annular slot including a sealing surface; and a seal disposed within said annular slot, said seal being configured to be engaged against said sealing surface when said first and second rotating components are rotated, wherein at least one circumferential flow gap is defined around a circumference of said seal when said seal is engaged against said sealing surface, where said flow gap provides for fluid communication from said high pressure cavity into said low pressure cavity. |
