Abstract:
An attenuation device, particularly a pulsation attenuator, has a casing (1) defining a fluid chamber (11) through which a fluid may flow along a flow axis (7), and has an attenuation element made of a resilient material located within the casing (1). The attenuation element has at least two annular bodies (15, 17) that are disposed in an at least partially overlapping manner, surrounding the flow axis (7) at least partially.
