Embodiment Construction
[0030] image 3 is a cross-sectional view of a housing with a filter structure according to the present invention.
[0031]In a cylindrical filter structure, one end of the cylindrical filter structure from which the discharge enters is completely open, and the other end of the cylindrical filter structure from which the discharge exits is partially sealed. The plurality of penetrating cells 12 are composed of sealed cells 15 and open cells 16 . All permeable cells are open at their entry ends. Half of the permeable cells are sealed at their outflow ends by sealant 14 and the remaining half of the permeable cells are open at their outflow ends. The open cells 16 and the sealed cells 15 are provided in substantially equal numbers, and the open cells may be arranged adjacent to the sealed cells so that they form a checkerboard pattern in the cross-section of the filter structure. Alternatively, the open cells may be arranged in a circle around the center of the filter structu...
