Abstract
A rotary device is disclosed that includes a rotor comprising a main body and plurality of protrusions extending radially from the main body. At least a pair of voids are provided adjacent to each other in the main body of the rotor between each adjacent pair of the plurality of protrusions, and each pair of voids is spaced from each adjacent pair of voids by a distance greater than that between each adjacent void in each pair of voids.
Claims14
A rotor comprising:
- a main body, the main body being configured to rotate around an axis of rotation;
- a plurality of protrusions extending radially from the main body;
- and
- at least a pair of voids adjacent to each other in the main body of the rotor between each adjacent pair of the plurality of protrusions, each pair of voids being separated from each adjacent pair of voids by a thickness in the circumferential direction greater than that between each adjacent void in each pair of voids.

A method for making a rotor that rotates around a first axis of rotation, the method comprising the steps of:
- forming a main body and plurality of protrusions extending radially from the main body;
- and
- forming at least a pair of voids adjacent to each other in the main body of the rotor between each adjacent pair of the plurality of protrusions, each pair of voids being separated from each adjacent pair of voids by a thickness in the circumferential direction greater than that between each adjacent void in each pair of voids.
