摘要： A filter apparatus includes a box-shaped casing formed by connecting peripheral edges of first and second casing members each having a concavity and a filter composed of first and second filter media placed one upon the other and having respective peripheries held between substantially the entire peripheral edges of the first and second casing members such that the filter assumes the shape of a bag when disposed in the casing. The casing has a suction port and an exhaust port each communicating between the interior and the exterior of the casing. The filter communicates with the exterior of the apparatus through the suction or exhaust port of the casing. The first and second filter media have respective through holes and are closely adhered together at peripheral portions of the respective through holes.

摘要： A filter assembly comprises a filter case having an opening end portion; a filter element inserted into the filter case; a set plate mounted to the opening end portion of the filter case and having an inlet and an outlet of fluid to be filtered; and a seal plate attached to the set plate and fixed to the opening end portion of the filter case by curling up an outer periphery portion thereof together with an edge portion of the opening end portion of the filter case. The set plate is mounted to the filter case with press fitting to ensure the mechanical contact to prevent the leakage of the fluid to be filtered. Thus, the filer assembly can effectively prevent leakage of fluid of high pressure, such as AT-fluid introduced therein.
