Patent ID: 8359850

Claim:
A hydrodynamic component ( 1 ), comprising at least two bladed shells (P, T, L) forming a torus shaped operating cavity ( 5 ) in combination, each comprising a dish ( 8 , 9 ) which supports the particular blades ( 6 , 7 ) over a portion ( 8 S, 9 S), wherein at least one of the bladed shells (P, T) comprises no support of the blades ( 6 , 7 ) through the dish ( 8 , 9 ) in the radially inner end portion ( 33 , 33 . 6 , 33 . 7 ) of the particular blades ( 6 , 7 ), wherein flow control means ( 12 , 12 . 6 , 12 . 7 ) are associated with said radially inner end portion ( 33 , 33 . 6 , 33 . 7 ) of the particular blades ( 6 , 7 ), which free end portion is not supported by the dish ( 8 , 9 ); wherein the flow control means ( 12 , 12 . 6 , 12 . 7 ) comprise at least one annular segment shaped or annular guide element ( 16 ), whose outer circumference ( 18 ) substantially defines the contour of the torus shaped operating cavity ( 5 ) in the portion ( 13 , 13 . 6 , 13 . 7 ) of the blade ends ( 33 , 33 . 6 , 33 . 7 ) without support, and which guide element is connected torque proof with the respective shell ( 8 , 9 ) of the bladed shell (P, T).
