Claims
- 1. A catalytic converter for the treatment of exhaust gases of internal combustion engines comprising:
- a housing defining an axial flow passage for the exhaust gases having an annular interior wall with an entrance end and an opposite discharge end;
- a monolithic ceramic honeycomb forming a catalyst carrier disposed in said flow path having exterior walls spaced radially inwardly of said-interior wall of said housing;
- a metal stop disc having an opening of a size smaller than an axial cross-sectional size of said catalyst carrier connected to said interior wall of said housing and extending radially thereof into said flow passage and axially spaced from said catalyst carrier at said housing entrance end and opposite discharge end;
- at least one first high temperature resistant compacted metal wire mesh disposed in the space between said carrier exterior wall and said housing interior wall adjacent said flow passage entrance and opposite discharge ends;
- a second high temperature resistant compacted metal wire mesh disposed in the axial spacing between said catalyst carrier and each metal stop disc adjacent said flow passage entrance and discharge ends; and
- a radially extending gasket disposed between said at least one first wire mesh and said second wire mesh at said flow passage entrance end for blocking a passage of exhaust gases through said at least one first wire mesh.
- 2. A catalytic converter according to claim 1, wherein said high temperature resistant compacted wire mesh is made of high nickel content alloy wire.
- 3. A catalytic converter according to claim 1, including a separate first wire mesh positioned adjacent said entrance and discharge end of said flow passage and spacer means for establishing and maintaining a spacing between said first wire mesh adjacent each of said entrance and discharge ends.
