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. 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.
