Title (EN) AIR AMPLIFIER, AIR CIRCULATION CIRCUIT
(FR) AMPLIFICATEUR PNEUMATIQUE, CIRCUIT À CIRCULATION D'AIR
(JA) エアー増幅器、エアー循環回路
Abstract:
(EN) Disclosed is an air amplifier, wherein air intake ports are disposed at the outer circumference of a passage route, which is formed at the interior of the amplifier, and through which a main air flow passes, and further an air box is disposed to cover the circumference of the air intake ports. Secondary air is collected by forming a secondary air introduction port in the air box. The main airflow passing through the passage route produces negative pressure inside the passage route, and this negative pressure draws the secondary air inside the air box through the air intake port and into the passage route.
(FR) La présente invention a trait à un amplificateur pneumatique pourvu d'orifices d'admission d'air disposés sur la circonférence extérieure d'un passage, qui est formé à l'intérieur de l'amplificateur, et à travers lesquels un écoulement d'air principal circule, et pourvu en outre d'un coffre d'air disposé de manière à recouvrir la circonférence des orifices d'admission d'air. De l'air secondaire est collecté grâce à un orifice d'admission d'air secondaire formé dans le coffre d'air. L'écoulement d'air principal circulant à travers le passage produit une pression négative à l'intérieur du passage, et cette pression négative amène l'air secondaire à l'intérieur du coffre d'air au moyen de l'orifice d'admission d'air puis dans le passage.
(JA)  エアー増幅器において、内部に形成されてメインエアーフローが通過する通過経路の外周にエアー吸入ポートを設け、更に、エアー吸入ポートの周囲を覆うようにしてエアーボックスを配置する。エアーボックスには、二次エアー導入口を形成することで、二次エアーが溜まるようにする。通過経路をメインエアーフローが通過することで通過経路内に負圧が発生し、この負圧によってエアーボックス内の二次エアーを、エアー吸入ポートを介して通過経路に向けて吸入する。
