  • Publication number: 20190111369
    Abstract: A device for separating liquid from a volume flow of a gas-liquid mixture may include a separating element and a deflection arrangement for deflecting the volume flow in a direction of the separating element to precipitate liquid on the separating element and thereby separate the liquid. The deflection arrangement may comprise a flow channel that extends axially away from a volume flow inlet and comprises an aperture area that extends axially on the flow channel. The aperture area may be at least partly covered by a covering means that is movable relative to the aperture area. The covering means may be movable to different extents at two axially-spaced locations to influence a magnitude of a part volume flow of the deflected volume flow flowing out of the flow channel through the aperture area at one axial location differently than at another axial location.
