ABSTRACT:
A separating apparatus which enables particles to be separated from a flowing medium by a preliminary separator which avoids the undesirably high pressure losses due to the flow resistance of known preliminary separators. The separating apparatus has a housing with an inlet and an outlet, in which a flow of air at the inlet end is caused to rotate by an inlet guide device, and is redirected again at the outlet end by an outlet guide device into a linear flow. The pressure recovery is achieved by a defined curvature and arrangement of the guide elements. The guide element curvature has an inlet contour, a retarding contour and a stabilizing contour. Preliminary separators of this type are used primarily in the air intake tracts of internal combustion engines exposed to heavy contamination, such as engines in farm machinery or construction machinery.
