Patent DE-19744237-A1 (DE)
Inventor: YU DEQUAN
IPC: F04D29/18
Filed: 1997-10-07
Abstract: An impeller has a plurality of vanes 54 radially extending from core 52, each having a sidewall 60 between a leading 56 and a trailing surface 58. A plurality of partitions 62 is interposed between the vanes, thereby defining a plurality of vane grooves 64. Fluid is pumped by the vanes through the grooves and flows along a generally spiral path F1 defining a primary vortex. A relief (e.g. a chamfer or radius) is formed at the intersection between the trailing surface 58 and the sidewall 60. This relief causes the fuel flowing along the path of the primary vortex to also rotate F2 about an instantaneous axis F1 thereby defining a secondary vortex, reducing turbulence, cavitation or vapour generation within the pump. The vanes may be angled or curved in the direction of rotation to increase the strength of the secondary vortex.
