摘要： A low profile catalytic converter is disclosed including substantially identical top and bottom housing plates and substantially identical top and bottom catalyst retaining plates sandwiched therebetween which define an inclined catalyst containing space of substantially uniform depth spaced inwardly at varying distances of the housing plates. The four plates have mating peripheral faces coterminous over substantially their entire peripheries adapted for edge-sealing and, further, define in combination peripherally spaced cylindrical contours adapted to receive exhaust inlet and outlet pipes wherein one of the contours is defined by a semi-cylindrical downwardly concave portion in the top housing plate, like-positioned downwardly concave portions in both retaining plates and an upwardly concave portion in the bottom housing plate, and the other contour is similarly defined by the housing plates but with upwardly concave portions in both retaining plates. In the preferred embodiment, the top and bottom housing plates are further characterized by a plurality of depressed portions therein bearing against the retaining plates and the structure includes a plurality of support studs extending between the housing plates at the depressed portions to provide a converter having high structural integrity and increased resistance to deformation.
