Patent ID: 8109074

Claim:
An engine system, comprising: a) a compressor or a turbocompressor for compressing a fluid; b) a first transfer positive displacement device for sequentially transferring controlled volumes of said compressed fluid; c) an intake conduit extending from said compressor or turbocompressor to said first positive displacement device; d) at least one second positive displacement device geometrically larger in volume than said first positive displacement device; e) a corresponding valveless passageway extending from said first positive displacement device to said at least one second positive displacement device; and f) a combustor for providing continuous combustion, said combustor being disposed within said corresponding passageway, such that each of said second positive displacement devices receives heated fluid from a corresponding combustor, wherein said first transfer positive displacement device is continuously sealed to prevent fluid communication between said intake conduit and said corresponding passageway and to prevent backflow of said heated fluid, wherein, during continuous flow of said fluid from said first positive displacement device to each of said at least one second positive displacement devices, work is performed in response to expansion of said heated fluid within said at least one second positive displacement device such that said engine system is not stallable when the pressure of said heated fluid within said corresponding passageway is greater than the pressure of said compressed fluid within said intake conduit.
