A fluid line muffler and fluid delivery line
By using multiple elastic bodies with different static stiffnesses to isolate the silencing elements from the flow cavity in the pipeline fluid silencer, efficient silencing under different fluid pressure environments is achieved, solving the problems of limited applicability and time delay in existing silencers, and improving the silencing effect and applicability.

AI Technical Summary
Existing pipeline fluid silencers are not effective at silencing noise in pipelines with changing fluid pressure, and their active control has a time delay problem, limiting their applicability.
Multiple elastic bodies with different static stiffnesses are used to separate the silencing element from the flow cavity. The passively controlled elastic bodies deform within different pressure ranges to transmit sound wave pressure pulsations to the silencing element for silencing, avoiding direct contact with the fluid and improving the applicability and silencing effect.
It achieves efficient noise reduction under different fluid pressure environments, has a wide range of applications, improves noise reduction effect, and eliminates the delay problem by eliminating the need for active adjustment of airbag pressure.
