摘要： A filter element of the present invention provides low pressure loss, superior filter performance and bonding of filtering material, and compactness. An inlet path (14) of a nearly semicircular configuration which is formed in the width direction of a filter element (3) is open at its upper side (71) and closed at its lower side (79). An outlet path (16) is closed at its upper side and open at its lower side. Corrugated filtering material (32) has continuous mountain portions (329) and valley portions (321). The mountain portions have a large radius of curvature R1, and the valley portions have a small radius of curvature R2. The valley portions are bonded to a flat filtering material (31,31a,31b). The open surface area of the inlet path is larger than the closed surface area of the outlet path (16). Preferably, R1/R2 is set so as to be within the range of 1.5 to 3.0.

摘要： The filter element of the present has a plurality of wavy portions which are so arranged that a plurality of wavy portions make a generally ring like structure. In order to reduce the pressure drop when the fluid flows through the filter element, the present filter element has a special shaped radial gaps. Namely, the width of a first radial gaps, which is formed within adjacent wavy portions and which connects with an inner space formed at the center of the generally ring like structure, increases from the outer end thereof to the inner end thereof. The width of a second radial gap, which is connected with outer atmosphere, decreases from the outer end thereof to the inner end thereof. Both axial ends of the wavy portions are covered with the adhesive sheet on which adhesive layer is cladded.

摘要： The filter body (1, 2) of the filter element has a plurality of first holes (3) which are sealed by glue (52) at their bottom ends and a plurality of second holes (31) which are open at their bottom ends. A sheet of thermoplastic adhesive (7) is placed on the top end of the filter body (1, 2) and melted so that the top ends of the second holes (31) are sealed closed. The thermoplastic adhesive is melted so as to expose the open ends of the first holes (3) (see Fig. 8). In this way, there is provided the conventional type of filter body (1, 2) in which fluid entering via the first holes (3) exits via the second holes (31) and is filtered as it passes from the first to the second holes (see Fig. 9).

摘要： In the filter element (E), a multiplicity of tubes (3) each formed of filtering material and having a substantially circular cross-section are arrranged side by side in a tubular assembly with the axes of the tubes lying parallel to one another; inter-tube openings are closed (52) at one end of the tubular assembly which serves as an inlet for a fluid to be filtered, whereas intra-tube openings are closed (53) at the opposite end of the tubular assembly; and the total cross-sectional area of all the inter-tube openings is smaller than the total cross-sectional area of all the intra-tube openings, but larger than the minimum cross-sectional area of a path through which the fluid is supplied to the tubular assembly. Specifically, one or more filtering materials (1,2) including a plurality of tubes (3) each having a substantially circular shape cross-section and connecting portions (12,22) interconnecting the adjacent tubes (3) are rolled into a spiral shape to provide the tubular assembly with the axes of the tubes arranged side by side parallel to one another.

摘要： @ A filter element has a generally ring-like structure which basically comprises a plurality of generally radial sections circumferentially arranged to define a central space. Each radial section has a plurality of circumferentially zigzag pleats formed from a ribbon of a filtering sheet material. The radial sections are circumferentially connected such that radially inwardly open generally radial spaces and radially outwardly open generally radial spaces are defined. The radially inwardly open radial spaces are closed at the axially opposite ends by end walls. Fluid to be filtrated can enter the radially outwardly open radial spaces and then passes through the zigzag pleats into the radially inwardly open radial spaces and thus into the central space. The ring-like structure has many modifications.
