A device according to the invention for closing a pivotable flap of a motor vehicle, in particular a motor-vehicle tailgate, comprises a first, hinge-bracket point of attachment for a spring on a hinge bracket of the flap; a second, bodywork point of attachment for a spring on a region which is fixed in relation to the flap; a spring, for example a tension spring or a pneumatic spring, which is arranged between the first, hinge-bracket point of attachment and the second, bodywork point of attachment; and a displacement device for the first, hinge-bracket or second, bodywork point of attachment of the spring. The displacement device can be activated by the control unit such that the first, hinge-bracket or the second, bodywork point of attachment of the spring is displaced from the starting position into a door-closing-displacement position, which can be determined by the control unit, with account being taken of the position of the motor vehicle, and in which the spring-force-opening moment, which results from the direction of action of the spring and the lever arm located at right angles thereto, is smaller than the closing flap-weight moment, in order for a closing movement of the flap to be initiated from the open flap position, and that the first, hinge-bracket or the second, bodywork point of attachment of the spring, in the event of a certain flap-pivoting position being detected, is reversed from the flap-closing displacement position into a reversing position at least a little closer to the starting position, in order for the closing energy of the flap to be reduced.

The invention relates to an actuating device for an exhaust flap of a boost pressure controller of turbocharged internal combustion engines, in which invention the exhaust flap is arranged pivotably in an exhaust-gas line, in particular in the housing of a turbine of an exhaust-gas turbocharger, and controls the opening cross section of a bypass line which bypasses the turbine in a manner which is dependent on the compressor-side boost pressure, wherein the exhaust flap is arranged on an actuating arm which is fastened on a shaft which is mounted rotatably in the exhaust-gas line, which shaft can be adjusted outside the exhaust-gas line via an actuating lever and a control rod which is articulated thereon and via a linear actuating motor. In order to avoid oscillation-induced buzzing noise in the actuating device, it is proposed that a frictional damper (34, 44, 46) is connected into the force flow between the shaft (24) and the control rod (30), in particular for system damping in the region of the exhaust flap (18).
