<P>PROBLEM TO BE SOLVED: To improve compressor efficiency or cycle efficiency while reducing pressure loss due to choking in an extraction part of a rotary machine. <P>SOLUTION: The extraction structure of the rotary machine C1 including a rotor having a plurality of rotary blades; a stator 2 provided around the rotor to define a flow passage of main flow of operating fluid together with the rotor; and the extraction part 3 provided adjacently to the flow passage while interposing a partition wall 21a of the stator 2 therebetween, to which the operating fluid extracted from the main flow is introduced through an extraction communication part formed in the partition wall 21a. The extraction communication part includes at least two extraction port rows 31 (31A, 31B) in which a plurality of extraction ports 41 extending through the partition wall 21a are aligned in the circumferential direction of the rotor. <P>COPYRIGHT: (C)2012,JPO&INPIT |
