The present invention relates to a control System (28) of at least one flap (24) of a fluid duct (22), in particular of an intake System (10), in particular of an internal combustion engine, in particular of a motor vehicle, and a fluid duct System. At least one swivel axis (26) is connected off-centered to the at least one flap (24). By the at least one swivel axis (26) the at least one flap (24) can be swiveled in the fluid duct (22) between positions with different degrees of opening. At least one swivel lever (30) is connected to the at least one swivel axis (26) for pivoting the at least one swivel axis (26). At least one elastic working return element (46) is connected directly or indirectly to the at least one swivel lever (30). The at least one return element (46) forces the at least one flap (24) toward a home position. An actuating lever (36) is mounted to a housing part of the fluid duct (22) swiveling round a rotation axis (38). The actuating lever (36) is mounted to the swivel lever (30) swiveling round a connection axis (32). The actuating lever (36) has a working surface (44) in which the at least one return element (46) applies to the actuating lever (36). The rotation axis (38), the connection axis (32) and the swivel axis (26) are parallel to each other. A distance (42) radial to at least one of the respective axis (32, 38) between the rotation axis (38) and the connection axis (32) and/or between the swivel axis and the connection axis and/or the working surface (44) and the connection axis (32) and/or between the working surface and the rotation axis is varying dependent on the opening/closing position of the at least one flap (24). |
