Yasuda, H

A catalytic converter for purifying the exhaust gases of internal combustion engine is presented that is comprised of a shell, said shell comprising a pair of half shells, each of said half shells having an inlet shell and a body shell, said body shells forming a catalyst chamber and said inlet shells forming a tapered inlet chamber, and a funnel-like outlet shell forming an outlet chamber, said outlet shell having a flange projecting radially and axially inwardly at an inner end thereof, a monolithic catalyst element in said catalyst chamber, resilient mounting means disposed on the periphery of said monolithic catalyst element in said catalyst chamber, said body shells form a shoulder adjacent said inlet shells, said shoulder comprising an annular inwardly directed portion integrally connecting said body shell with said inlet shell of each of said half shells, an annular rim having a substantially l-shaped cross-section disposed at a front end of said monolithic catalyst element and including a radial portion between said resilient mounting means and first resilient means and an axial portion, the latter defining an inlet for the exhaust gases into said monolithic catalyst element, first resilient means disposed between said radial portion of said annular rim and said shoulder of said body shells, second resilient means disposed between a rear end of said monolithic catalyst element and said flange of the outlet shell, said inlet shells defining a pair of inlet ports of said inlet chamber adapted to communicate with upstream exhaust pipes, and said outlet shell forming an outlet port of said outlet chamber adapted to communicate with a downstream exhaust pip.e
