Patent ID: 7958862

Claim:
An engine comprising: a combustor assembly having first and second spiral bands configured to engage with one another to provide a first zone to transfer fluid outward in a radial direction from an intake chamber of the combustor assembly upon movement of the first spiral band with respect to the second spiral band; and an ignition source configured to combust fluid in the first zone; a compressor assembly having third and fourth spiral bands configured to engage with one another to provide a second zone to transfer fluid inwardly in a radial direction to an outlet chamber of the compressor assembly upon movement of the third spiral band with respect to the fourth spiral band; and a shaft assembly coupled with the combustor assembly and the compressor assembly and having a barrel shaft and an orbital shaft, located within the barrel shaft and coupled with the barrel shaft in a manner to facilitate relative movement between the orbital shaft and the barrel shaft, the orbital shaft to transfer fluid from the outlet chamber to the intake chamber, wherein combustion of fluid in the first zone facilitates orbital rotation of the orbital shaft within the barrel shaft, which, in turn, facilitates said transfer of fluid inwardly to the outlet chamber of the compressor assembly.
