The invention relates to a device for precipitating liquid and/or particulate impurities from a gas stream, comprising at least one first guiding element and at least one second guiding element, it being possible to impose at least one first change in direction on the gas stream by means of said first guiding element, and to impose at least one second change in direction on the gas stream by means of the second guiding element, the fluid stream additionally flowing in a substantially laminar manner along the first guiding element and the second guiding element.

Device for the precipitation of particles from a gas stream

A device separates particles such as oil particles from a gas flow, from a blow-by gas of a crankcase ventilation, in an internal combustion engine. The device includes a valve seat that defines a flow passage opening and a movable valve element that can be displaced between a closed position, in which the valve element is in abutting contact with the valve seat and the abutting contact defines an axial abutting point, and at least one open position, in which the valve element is moved from the axial abutting point in an axial actuating direction, wherein at least one abutting contact surface of the valve element and/or the valve seat is contoured in such a way that a fluid passage is allowed in the closed position.

Device for separating particles from a gas flow, particle separator and crankcase ventilation system

A device separates particles, such as oil particles, from a gas flow, from a blow-by gas of a crankcase ventilation, in an internal combustion engine. The device includes a valve seat, which defines at least one flow passage opening and through which the gas flow at least partially flows in a main flow direction, and a movable valve element, which can be adjusted relative to the valve seat such that flow guide surfaces of the valve seat and the valve element deflect the gas flow in such a way that particles separate from the gas flow due to the impact of the particles on the flow guide surfaces. At least one flow guide surface of the valve seat or the valve element has at least one turbine blade-like guide projection or at least one turbine blade-like guide depression in order to transform the gas flow into a swirling flow.

The movable valve element has a rotationally symmetrical bowl upstream of the gas flow, and a base of the bowl axially protrudes past the abutting point opposite to the axial actuating direction.
