Abstract
The invention is related to a pulsation muffler (100) for a gaseous medium flow (107), which is supplied by a compressor. The pulsation muffler (100) comprises a housing (101) extending along a central axis with a medium flow inlet (106) and a medium flow outlet; several tubular absorber elements (108) concentrically arranged in the housing (10) and fluidically arranged one behind the other. Each tubular absorber element (108) is provided with an inlet area and an outlet area, positioned at an axial distance from each other. Between the respective radially adjacent wall sections of different absorber elements (108), a flow compartment (112, 114) is maintained for the medium flow (107).
Claims10
A pulsation muffler (100) for a gaseous medium flow (107) supplied by a compressor, the pulsation muffler comprising:
- a housing (101) extending along a central axis with a medium flow inlet (106) and a medium flow outlet (116);
- and
- a plurality of tubular absorber elements (108), each made of sound-absorbing material, arranged concentrically in the housing (101), wherein
- each of said tubular absorber elements (108) is provided with an inlet area and an outlet area, positioned at an axial distance from each other,
- the inlet area of the fluidic front absorber element (108a) is connected to the medium flow inlet (106) of the housing (101), the outlet area of the fluidic front absorber element (108 a) is connected to the inlet area of the next fluidic absorber element (108b), and the outlet area of the fluidic rear absorber element (108c) is connected to the medium flow outlet (116) of the housing (101), and
- a flow compartment (112, 114) is maintained for the medium flow (107) between the respective radially adjacent wall sections of different absorber elements (108).
