Abstract
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.
