Abstract

A separator device, particularly a separator for separating particles from an air stream, which includes a first stage having at least one centrifugal separator through which the fluid flows along a first axial path. The centrifugal separator has a guide device for generating a spiral movement of the fluid. A second stage is directly downstream from the first stage and has an essentially cylindrical housing. A dust discharge is provided in the area of the fluid outlet, and a central pipe which is arranged concentrically and has a truncated conical shape is provided in the second stage.

Claims

1. A separator device for separating particles from a stream of fluid, said separator device comprising a first stage with at least one centrifugal separator through which the fluid flows in along a first axial path, said at least one centrifugal separator having a fluid guide member for generating a spiral movement of the fluid, and said separator device further comprising a second stage directly downstream from the first stage;

said second stage comprising an essentially cylindrical housing with a fluid outlet for a cleaned stream of fluid, a concentrically arranged frustoconical central tube and a dust discharge for separated particles in the area of the fluid outlet, and a conical insert in the second stage for improving the degree of separation.

2. A separator device according to claim 1, wherein said fluid is air and said particles comprise dirt and dust particles.

3. A separator device according to claim 1, wherein the second stage has a fluid inlet which extends at least partially into the first stage.

4. A separator device according to claim 1, further comprising a common collecting vessel for collecting particles separated by the first stage and particles separated by the second stage.

5. A separator device according to claim 1, wherein said device comprises a plurality of centrifugal separators arranged in an array.

6. In an air intake for an internal combustion engine, the improvement comprising a separator device according to claim 1, arranged to separate dirt or dust from an air stream passing through said air intake.
