<p>PURPOSE:To prevent generation of unbalance without causing raised processing accuracy and enhance the compression ratio by furnishing ducts in the form of an arc of circle in that position of each notch in a cylinder that is mating with the rotary disc vane part, and by putting the start and end terminals of adjoining ducts in communication. CONSTITUTION:When a rotary disc 3 is rotated, the gas from arrow B is moved by provided vanes from a communication path 10a to a duct 9, and turns in the next communication path to move down communication path upon passing the next duct. Here the gas is moved through the duct 9 and communication path by the vanes at the outer side of the undersurface of the rotary disc 3. The gas sucked in from arrow B passes the gap between rotary disc 3 and cylinder 7 to be fed back to the duct 9, and is compressed while exhausted from arrow F. Formation of 4 compression stages is possible with this single rotary disc 3, and lamination of them allows provision of sufficient long duct 9 in the condition dynamic balance is made better without causing raised processing accuracy compared with the conventional method, and should enhance the compression ratio to a great extent.</p> |
