Abstract
A pump employing a nutating plate within a chamber impels fluid flow from an axial inlet to a peripheral outlet. The chamber extends 360° and the plate has holes about the axis thereof such that both sides of the plate can operate to impel fluid through the chamber. A dynamic balancing system which may include two dynamic balancing rings with multiple weights therein act to overcome eccentricities and vibrational moments.
Claims56
A pump comprising
- a chamber housing including a chamber, an axial inlet to the chamber and a peripherial outlet from the chamber;
- a plate mounted for nutation within the chamber about an axis of nutation.
A pump comprising
- a substantially circular plate mounted for nutation about an axis of nutation;
- a chamber housing including a substantially circular chamber extending continuously 360° about the axis of nutation, an inlet to the chamber and an outlet from the chamber, the plate being within the chamber.
A pump comprising
- a chamber housing including a chamber having a periphery which is a full circle, an axial inlet, and a peripheral outlet;
- a circular plate mounted for nutation within the chamber, the circular plate including an attachment hub concentrically positioned in the plate and holes radially adjacent to the hub and extending through the plate.
A pump comprising
- a chamber housing including a substantially circular chamber, an axial inlet to the chamber, and a peripheral outlet from the chamber;
- an impeller element within the chamber;
- a shaft housing fixed relative to the chamber housing;
- a drive shaft rotatably mounted in the shaft housing about an axis of rotation, the impeller element being coupled with the drive shaft;
- a first dynamic balancing ring at the drive shaft and rotatable therewith and including multiple weights movable within the first dynamic balancing ring.
2 more elements
A pump comprising
- a plate means for impelling fluid being substantially circular and mounted for nutation about an axis of nutation;
- a chamber housing including a substantially circular chamber means for receiving the fluid extending continuously 360° about the axis of nutation, an inlet means for directing the fluid to the chamber and an outlet means for directing fluid from the chamber, the plate means being within the chamber means.
