摘要：A control valve for controlling a fluid flow is disclosed, in particular a coolantflow in a coolant circuit of an internal combustion engine, including a valve element whichis provided with at least one opening, and which can move relative to a valve housing.With a movement of the valve element, the at least one opening can be brought into aposition in which it overlaps a line cross-section defined on the valve housing side, inorder to permit a flow of fluid. In addition, a sealing element is provided which is

accommodated on the valve housing such that it radially surrounds the line cross-section,and a sealing surface of which can be brought into contact with a surface of the valveelement, thus bridging a gap that extends between the surface of the valve element andthe valve housing in a region of the sealing element. In order to provide a control valvethat has minimal friction losses over the working range thereof, the extent of the gapchanges according to the movement of the valve element in relation to the valve housing.In addition, the extent of the gap reaches a maximum in a region in which the at least oneopening overlaps the line cross-section, at which extent the sealing element with itssealing surface is raised from the surface of the valve element.
