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.
Claims31
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 drive coupling fixed to the plate;
- a spherical mounting including a mounting block having a spherical seat defining a center of nutation and a spherical bearing mated with the mounting block at the spherical seat, one of the mounting block and the spherical bearing being fixed relative to the chamber housing and the other of the mounting block and the spherical bearing being fixed relative to the drive coupling.

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 drive coupling fixed to the plate;
- a spherical mounting including a mounting block having a spherical seat defining a center of nutation and a spherical bearing mated with the mounting block at the spherical seat, one of the mounting block and the spherical bearing being fixed relative to the chamber housing and the other of the mounting block and the spherical bearing being fixed relative to the drive coupling.

A pump comprising
- a chamber housing including a chamber, an axial inlet to the chamber, a peripheral outlet from the chamber and an access port;
- a plate within the chamber;
- a drive coupling extending through the access port and mounting the plate for non-rotational nutation about an axis of nutation through a center of nutation;
- a seal extending to the chamber housing from about the drive coupling about the center of nutation;
- a spherical mounting including a mounting block having a spherical seat defining) a center of nutation and a spherical bearing mated with the mounting block at the spherical seat, one of the mounting block and the spherical bearing being fixed relative to the chamber housing and the other of the mounting block and the spherical bearing being fixed relative to the drive coupling.
