  • Air cleaner
    Patent number: 7360530
    Abstract: A housing 11 accommodates a pleated filter element 14. A fuel adsorbent member 16 is arranged in the housing 11 at a position downstream from the filter element 14. The fuel adsorbent member 16 adsorbs evaporative fuel leaking from an engine. The fuel adsorbent member 16 includes holding pleats 16g. Each of the holding pleats 16g is received in the space between an adjacent pair of the element pleats 14a of the filter element 14. This maintains the interval between the element pleats 14a. The holding pleats 16g are formed by folding the fuel adsorbent member 16.
    Type: Grant

  • Production method and apparatus for filter, forming die for filter, forming assembly for forming filter, and filter
    Patent number: 6732868
    Abstract: A filter production method produces a filter having a shape substantially identical to the shape of a forming surface by extruding semi-molten fibers to the forming surface. When the semi-molten fibers are extruded to the forming surface, the semi-molten fibers are gathered to upstanding surface portions of the forming surface. Therefore, a sufficient amount of fibers can be layered onto the upstanding surface portions, so that the layering amount of fibers on the upstanding surface portions of the forming surface will not be considerably reduced in comparison with the layering amounts on other portions of the forming surface.
