  • the blade 34 is connected to an axle 342 which is pivotably connected between the protrusion 44, 54 of the other two first and second pieces 40, 50.
  • the first and second pieces 40, 50 drive the blades 32, 34 by the axles 322, 342 and the blades 32, 34 rotate about the center of the room 13.
  • the blades 32, 34 move along the slots 23 back and forth.
  • Fig. 15 shows the sixth embodiment of the present invention and comprises a stator 10, a rotor 20, a first blade 36, a second blade 38, a first piece 40 and a second piece 50.
  • the differences between the first and sixth embodiments are that the first and second pieces 40, 50 are ring-shaped pieces and the first pieces 40 are mounted to the first protrusion 17 and the second pieces 50 are mounted to the second protrusion (not shown).
  • the first piece 40 and the second piece 50 are pivoted about the center of the room 13.
  • the first and second pieces 40, 50 respectively form a pivotal hole 46/56 and a circular guide slot 48/58.
  • the first blade 36 is pivotably connected to an axle 362 and two ends of the axle 362 are pivotably connected with the pivotal holes 46, 56 of the first and second pieces 40, 50.
  • the first and second pieces 40, 50 drive the first blade 36 to pivot about the center of the room 13 by the axle 362.
  • the second blade 38 is pivotably connected to a first axle 382 and a second axle 384.
  • the first axle 382 is connected to a first slide 386 and the second axle 384 is connected to a second slide 388.
  • the first slide 386 is slidably inserted into the guide slot 48 of the first piece 40 and the second slide 388 is slidably inserted to the guide slot 58 of the second piece 50.
  • the first and second pieces 40, 50 drive the first and second axes 382, 384 to rotate the second blade 38 to be pivotable about the center of the room 13.
  • the first and second slides 386, 388 are movable along with the guide slots 48, 58 back and forth.
  • Fig. 16 shows the seventh embodiment which is amended from the fifth embodiment, wherein the first and second pieces 40, 50 are located symmetrically relative to the cylindrical body 21.
  • the first piece 40 has a pivotal hole 46 and a curved guide slot 48.
  • the pivotal hole 46 and the guide slot 48 are defined in the first side of the first piece 40, the second side of the first piece 40 is a closed side.
  • the second piece 50 has a pivotal hole 56 and a curved guide slot 58.
  • the pivotal hole 56 and the guide slot 58 are defined in the first side of the second piece 50, and the second side of the second piece 50 is a closed side.
  • the embodiments described in the above can utilize an inverter motor to connect the shaft of the rotor to control the flow rate of the fluid.
