(JA) フィルター用リテーナ
Abstract: front page image
(EN)A filter retainer (1) having filtering materials supported on opposite surfaces of the filter retainer. A pair of etched circular plates (3a, 3b) having a large number of circumferentially arranged through-holes (4) formed by chemical etching is joined together with the positions of corresponding through-holes (4) aligned with each other and with radially extending inner paths (8) formed between the pair of etched circular plates (3a, 3b). The structure of the filter retainer is totally novel and clears up various problems, such as accuracy and pressure loss, of conventional filter elements caused by internal structures thereof.
(FR)L'invention porte sur un dispositif de rétention de filtre (1) ayant des matières de filtration supportées sur des surfaces opposées du dispositif de rétention de filtre. Une paire de plaques circulaires gravées (3a, 3b) ayant un grand nombre de trous traversants (4) disposés sur la périphérie formés par gravure chimique est assemblée avec les positions des trous traversants (4) correspondants alignées les unes avec les autres et avec des voies de passage (8) internes s'étendant radialement formées entre la paire de plaques circulaires gravées (3a, 3b). La structure du dispositif de rétention de filtre est totalement nouvelle et élimine divers problèmes, tels que la précision et la perte de charge, d'éléments filtrants classiques provoqués par les structures internes de ceux-ci.
(JA) 両面上に濾材を支持するフィルター用リテーナ(1)であって、化学的エッチングにより形成された貫通穴(4)が周方向に多数配列された一対のエッチング処理円板(3a、3b)が、対応する各貫通穴(4)の位置を一致させた状態で、互いに接合されており、接合された形態にて、一対のエッチング処理円板(3a、3b)間に径方向に延びる内部通路(8)が形成されていることを特徴とするフィルター用リテーナ。従来のフィルターエレメントの内部構造による精度や圧力損失等の種々の問題点を一挙に解決可能な全く新規な構造のフィルター用リテーナを提供できる。
