A reactor for purifying exhaust gas in an exhaust gas system of an internal combustion engine comprises an inner shell forming a reaction chamber and an outer shell surrounding the inner shell and defining an adiabatic zone therebetween. A pipe member extends through the outer shell to the inner shell for absorbing the heat expansion of the inner shell. The pipe member disposed for movement in the axial direction and in the direction normal to the axis of the pipe member relative to the outer shell for maintaining the seal between the adiabatic zone and the reaction chamber. |
