| 20100247354 | ANGULAR OSCILLATION CENTRIFUGAL PUMP - A turbo type centrifugal pump is provided in which an angular oscillator is angularly oscillated so that fluid in a radial through hole receives centrifugal force. The angular oscillator is used in combination with a resonance oscillation motor that generates angular oscillation. The resonance oscillation motor is incorporated in the pump so that the pump structure and the drive mechanism are integrated. This reduces the size of the pump. Since the angular oscillation is a reciprocating rotation within an oscillation range less than 360°, a suction pipe can be connected to the radial through hole used in the angular oscillation. This eliminates the necessity for providing a shielding structure. | 09-30-2010 |
