Abstract

Apparatus adapted to receive one or more catalysts for the decontamination of exhaust gas of internal combustion engines. The apparatus, which includes a closed container for one or more beds of catalyst, is provided with an inlet for introducing exhaust gas thereinto and with an outlet for removing decontaminated exhaust gas therefrom. The catalyst beds are maintained in position by means of a spring-actuated clamping device which comprises a thrust rod, a mounting therefor and a spring element. The spring element, which bears against the mounting, urges the thrust rod into close contact with the catalyst beds.
