    摘要: A rotary fluid-control valve for controlling fluid flow has a cylindrical valve chamber, a dove-tail shaped valve body mounted rotatably in the valve chamber and movable between an open position and a closed position, and four fluid passages extending from the valve chamber. The passages are arranged essentially parallel with respect to one another and the valve body is pivotally connected to the valve chamber with a pivot pin extending in the axial direction of the valve chamber. The passages extend perpendicular to the pivot pin. The valve chamber has a convex section that, when the valve body is rotated out of the closed position, causes an asymptotic rise in the throughflow quantity. A stop or pressure equalizing projection projects into the valve chamber and is dimensioned so that a pressure drop in the closed position of the valve body corresponds to a pressure drop of the radiator in the open position of the valve body. The valve body further has a concave portion extending along one side of the first and second valve arms to provide a homogenous bypass flowthrough through the valve chamber.

    摘要: A device for cooling drive components and heating a passenger compartment of an electric vehicle, having a drive motor fed by a battery, comprises a first coolant circuit which is coupled by an intermediate heat exchanger to a second coolant circuit. In the second coolant circuit there is provided a first heat exchanger, acting as a cooling element, and a second heat exchanger, acting as a heating element. The heat exchangers disposed in the second coolant circuit are provided with a respective controllable bypass. A control unit registers a plurality of temperature states and signals derived from the battery control unit and processes these in order to actuate corresponding adjusting and drive means for the flow of the cooling medium.
