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).
Claims20
A pulsation muffler for a gaseous medium flow supplied by a compressor, the pulsation muffler comprising:
- a housing extending along a central axis with a medium flow inlet and a medium flow outlet, the medium flow outlet axially aligned with the medium flow inlet and having a cross sectional area that is larger than a cross sectional area of the medium flow inlet;
- a plurality of tubular absorber elements, each made of sound-absorbing material, arranged concentrically in the housing, the plurality of tubular absorber elements including
- a fluidic front absorber element,
- a fluidic rear absorber element, and
- a fluidic intermediate absorber element disposed between the fluidic front absorber element and the fluidic rear absorber element, wherein
- each of the fluidic front absorber element, the fluidic rear absorber element, and the fluidic intermediate absorber element includes an inlet area and an outlet area positioned at an axial distance from the inlet area, wherein the inlet area of the fluidic front absorber element is connected to the medium flow inlet, the outlet area of the fluidic front absorber element is connected to the inlet area of the fluidic intermediate absorber element, and the outlet area of the fluidic rear absorber element is connected to the medium flow outlet;
- and
- a plurality of flow compartments defined between respective tubular absorber elements of the plurality of tubular absorber elements to permit flow of gaseous medium between radially adjacent wall sections of respective tubular absorber elements of the plurality of tubular absorber elements.
