摘要： A control valve is provided, in particular for metering in a fluid for a delivery pump which is arranged downstream. The control valve has a flow channel, an axially movable valve needle, and a valve element which can be loaded by the valve needle in an opening direction and is arranged in the flow channel. If the valve element is actuated in the opening direction by the valve needle, the fluid can flow back through the flow channel at least temporarily counter to the opening direction of the valve element. Upstream of the valve element as viewed in the backflow direction, the flow channel has a fluidically active shield which keeps the backflow at least partially free of a face of the valve element.
