Abstract

An arrangement for throttling a fluid flow includes a throttle element arranged so as to influence a flow cross section in a fluid duct. The throttle element has a resiliently elastic disc-shaped basic body which is arranged with a top side and a bottom side between at least two supports in the fluid duct. The body is arranged in such a way that the flow cross section can be variably adjusted as a function of a pressure difference between the top side and the bottom side of the resiliently elastic disc-shaped basic body. At least one support bears against the top side of the resiliently elastic disc-shaped basic body, and at least one support bears against the bottom side of the resiliently elastic disc-shaped basic body.
