  • the structure and function of the air suction ports 410B and 410C are the same as those of the air suction port of the first example, and thus description thereof is omitted.
  • the air flow resistance is reduced, and the amplification efficiency can be increased.
  • the spiral groove 410D generates a swirl in the main air flow and improves amplification efficiency.
  • an air amplifier 501 according to the fifth example will be described with reference to FIG.
  • parts different from the air amplifier 601 of the first example will be mainly described, and the same or similar parts will be described and illustrated by matching the last two digits of the reference numerals with the first example. Is omitted.
  • the first chamber 512 and the second chamber 514 can be separated. Further, the inner diameter d2 of the second chamber 514 is smaller than the inner diameter d1 of the first chamber 512. Thus, the flow velocity is increased by reducing the inner diameter of the compartment toward the downstream side.
  • the passage hole 512B of the first chamber 512 is thinner than the diameter of the second chamber 514 on the downstream side. Further, here, the passage hole 512B itself has a tapered shape that becomes gradually thinner toward the downstream side, so that the flow velocity of the air is increased.
  • an air suction slit 514E having a ring shape is disposed around the outlet of the passage hole 512B by utilizing a step due to the difference in diameter between the passage hole 512B and the second chamber 514. Further, a plurality (eight in this case) of air suction ports 514D are arranged at equal intervals in the circumferential direction in the air suction slit 514E.
  • Main air flow is discharged to the second chamber 514 side through the passage hole 512B. As a result, the air amplification efficiency can be increased.
  • a diffuser 514F On the downstream side of the second chamber 514, a diffuser 514F whose diameter gradually increases is provided.
  • a check valve (check valve) 514G is installed in each air suction port 514D.
  • the air circulation circuit of this embodiment has prepared two systems, the power air circulation circuit P and the auxiliary air circulation circuit Q. Therefore, the power air circulation circuit P can be further stabilized by using the output of the auxiliary air circulation circuit Q for driving and charging the continuous air generation circuit R.
  • the driving force of the power air motor 112 can be increased by supplementing the compressed air using the auxiliary air motor 12 in order to increase the supplied air pressure. Suppresses the decline.
  • the auxiliary air circulation circuit can be used as an output control device for the power air circulation circuit.
  • the present embodiment shows the case where the check valves 7 and 107 are arranged in the air supply path before the three-way valves 8 and 108 in the power air circulation circuit P and the auxiliary air circulation circuit Q, respectively.
  • the three-way valves 8 and 108 themselves give priority to the high pressure in comparison with the compressed air sent from the air tank 3 and the air sent from the fourth surge tanks 20 and 120.
  • the check valves 7 and 107 are not necessary if a device having a function for sending to 9, 109 is used.
  • the present invention can easily obtain the rotational power of the air motor by effectively arranging the air amplifier on the air circulation circuit. Furthermore, by providing an auxiliary air circulation circuit as an air circulation circuit, the output of the power air circulation circuit is stabilized.
