Abstract
(EN)
A swirl flow generating part (32) is provided in a separation unit (23). Air supplied from the outside to a port (11) on the primary side is formed into a swirl flow by the swirl flow generating part (32). Foreign matter such as droplets and dust included in the air goes along the inner peripheral surface of a separation chamber (25) because of centrifugal force and is exhausted into a recovery vessel (27) from an exhaust opening (31) in the separation unit (23). The air from which foreign matter has been eliminated and which has been cleaned is guided to a port on the secondary side by a discharge pipe (37) disposed in the central part of the swirl flow generating part (32). A swirl regulating plate (61) is provided in the discharge pipe (37); the swirl motion of the air flowing into the inside of the discharge pipe (37) is regulated, and the noise generated by the filter is reduced.

La présente invention concerne une partie de génération d'écoulement tourbillonnant (32) qui est disposée dans une unité de séparation (23). De l'air alimenté depuis l'extérieur vers un orifice (11) sur le côté primaire est formé dans un écoulement tourbillonnant par la partie de génération d'écoulement tourbillonnant (32). Une matière étrangère telle que des gouttelettes et des poussières incluses dans l'air se déplace le long de la surface périphérique interne d'une chambre de séparation (25) en raison de la force centrifuge et s'échappe dans une cuve de récupération (27) par une ouverture d'échappement (31) dans l'unité de séparation (23). L'air duquel la matière étrangère a été éliminée et qui a été nettoyé est guidé vers un orifice sur le côté secondaire par un tuyau de décharge (37) disposé dans la partie centrale de la partie de génération d'écoulement tourbillonnant (32). Une plaque de régulation de tourbillonnement (61) est disposée dans le tuyau de décharge (37) ; le mouvement tourbillonnant de l'air s'écoulant à l'intérieur du tuyau de décharge (37) est régulé, et le bruit généré par le filtre est réduit.

 分離ユニット23には旋回流発生部32が設けられている。1次側ポート11に外部から供給された空気は旋回流発生部32により旋回流となる。空気中に含まれている液滴や塵等の異物は遠心力によって分離室25の内周面に沿って、分離ユニット23の排出口31から回収容器27内に排出される。異物が除去されて清浄化された空気は、旋回流発生部32の中心部に配置された排出管37により2次側ポートに案内される。排出管37には旋回規制板61が設けられており、排出管37の内部に流入する空気の旋回運動が規制され、フィルタから発生する騒音が低減される。
