Abstract
A catalytic converter of a radial flow type including an outer casing, a cylindrical outer separator, and a cylindrical inner separator, the two separators defining a catalyst chamber therebetween, wherein the end portions at one end of the two separators are firmly connected to the outer casing while the other end portions of the two separators are formed as mutually telescoping closed free ends having a radial and an axial clearance therebetween, these free end portions being flexibly supported from the outer casing by means of a plate element.
Claims13
A catalytic converter of a radial flow type comprising an outer casing, an outer separator formed as a cylindrical element having a large number of small openings and mounted in said outer casing so as to define an outer chamber between said outer casing and said outer separator, an inner separator formed as a cylindrical element having a large number of small openings and mounted in said outer separator so as to define an annular intermediate chamber between said outer and inner separators while defining an inner chamber at the inside thereof, a first port means connected with said outer chamber, a second port means connected with said inner chamber, said outer and inner separators having first end portions firmly connected with said outer casing and mutually telescoping closed second ends, an L-shaped flexible support plate element having a first end portion connected with said outer casing and a second end portion connected with said second end portion of said outer separator, thereby directly supporting said second end portion of said outer separator from said outer casing in radial and axial directions while permitting relative displacement of the outer separator with respect to the outer casing both in the radial and the axial directions so as to relieve thermal stress, and catalyst material charged in said annular intermediate chamber.
A catalytic converter housing of a radial flow type comprising an outer casing, an outer separator formed as a cylindrical element having a large number of small openings and mounted in said outer casing so as to define an outer chamber between said outer casing and said outer separator, an inner separator formed as a cylindrical element having a large number of small openings and mounted in said outer separator so as to define an annular intermediate chamber between said outer and inner separators while defining an inner chamber at the inside thereof, a first port means connected with said outer chamber, a second port means connected with said inner chamber, said outer and inner separators having first end portions firmly connected with said outer casing and mutually telescoping closed second ends, and an L-shaped flexible support plate element having a first end portion connected with said outer casing and a second end portion connected with said second end portion of said outer separator, thereby directly supporting said second end portion of said outer separator from said outer casing in the radial and the axial directions while permitting relative displacement of the outer separator with respect to the outer casing both in the radial and the axial directions so as to relieve thermal stress.
