Around rotors (14,15) are provided, in a machine housing with rotating teeth, compressors or teeth expanders working with a high compression ratio and a near zero volume value between the teeth when they pass the high pressure port area (21). Thin-walled shell construction rotors (14,15) have corresp. connecting rails in the teeth. Conducting surfaces and fixed rails in their hubs permit the building of peripheral channels for coolant within the outer shells of the rotors. |
