An inline heating device for fluid has rotary members frictionally engaging fixed housing extensions on a central fluid transfer conduit. A first valve is located near the first end of the conduit and a second valve is located near the second end of the conduit. The particle flow is advantageously further reinforced in the direction of the gas sink by an oppositely arranged gas supply device. The machine comprises means for placing the cavity in fluidic communication with a volume situated outside the bearing near the second edge of the bearing. If the cache memory controller determines that the access will result in a cache hit, data are coupled from the DRAM array to the processor.
