The invention concerns a device for separating fluid particles from a gas flow, in particular from a crankcase gas flow of an internal combustion engine. A valve is provided to allow a distribution of the gas flow to at least two cyclones depending on the volumetric flow. The valve consists of a cylinder through which the gas can flow. Inside the cylinder is a piston. This piston is designed inside the cylinder with a clearance fit or provided with one or several boreholes. In case of a low gas flow and because of the tolerances or boreholes, this gas flow will be directed around the cylinder to a first cyclone. When exceeding a certain volumetric flow the piston moves inside the cylinder and opens at least one more cyclone for the gas flow to flow through. |
