Zusammenfassung: | The present invention relates to drive arrangements for assemblies of an internal combustion engine, in particular exhaust-gas recirculation valves, having a drive element (12), a housing (10) and an intermediate element (64) that is arranged so as to be preloaded between the drive element (12) and the housing (10); To achieve all-round vibration decoupling of the drive element, it is proposed that the housing (10) have a static receiving part (32) and a cover (38) fastened thereon, which cover bears axially against a stop (60) on the static receiving part (32), wherein the intermediate element (64) is arranged radially between the cover (38) and the drive element (12) and so as to be elastically deformed axially between the drive element (12) and the cover (38), such that, in the case of an exhaust-gas recirculation valve, the electric motor (12) is loaded axially against a drive-side bearing bracket (42), which is formed on the housing (10), by the spring force of an elastically deformed intermediate element (64) and is mounted in the cover (38) radially by means of the intermediate element (64). |
