Abstract

An assembly includes: a first component; a second component enclosed by the first component; a diaphragm that covers a radial gap between the first and second components and is fixed in each case in a sealed manner; and a volume of a medium that is enclosed by the first and second components and the diaphragm. For the purpose of achieving a simple filling process of the assembly with the medium at a reliable sealing of the enclosed volume, even in the case of high, swelling pressures acting upon the assembly, in one of the components a filling valve is situated that opens towards the volume, which filling valve is situated as a check valve having spring resetting in a filling channel running in the component.
