Abstract
A fluid-moving rotary device that has a drive mechanism whose rotational axis is aligned with a rotational axis of a driven component and another component that rotates about an axis offset from rotational axis of the driven component. The drive mechanism is located on a fluid inlet side of the components and is cooled by the fluid entering the device.
Claims8
A rotary device, comprising:
- a housing,
- a first component rotatable about a first axis within the housing,
- a second component within the housing and configured to rotate about a second axis offset from the first axis and relative to the first component;
- and
- a drive mechanism within the housing and having a shaft whose rotational axis is aligned with the first axis of the first component, with one end of the shaft of the drive mechanism being operatively connected with the first component for driving the first component and another end of the drive mechanism being supported by a bearing arrangement,
- wherein passages are grouped together and contained in an offset portion of the housing that only partially surrounds the rotational axis for allowing a main fluid to flow through the rotary device.
