PROBLEM TO BE SOLVED: To attain the highest possible separation degree even in a low volumetric flow.SOLUTION: At least one acceleration opening (16) is positioned in a housing wall area, the housing wall area is covered with a flexible diaphragm (14''') formed in a plate shape on one side of the opening, an outer wall of the diaphragm (14''') forms an annular gap having a gap height in the axial direction between a minimum value of reaching to 0 and a maximum value to a housing wall in relation to the volumetric flow, and the annular gap communicates in a radial outward direction from the housing wall area covered with the diaphragm (14'''). |
