Control system of at least one flap of a fluid duct and fluid duct system

摘要

A control system of at least one flap of a fluid duct of an intake system of an internal combustion engine, including: a swivel axis, at least one flap connected off-center to the swivel axis by which the at least one flap can be swiveled within the fluid duct between positions with different degrees of opening, a swivel lever connected to the swivel axis, the swivel lever pivoting the swivel axis, an elastic working return element connected directly or indirectly to the swivel lever and applying a force to the at least one flap to return the at least one flap toward a home position.

1. A control system of at least one flap of a fluid duct of an intake system of an internal combustion engine, comprising:
a swivel axis; at least one flap connected off-center to the swivel axis by which the at least one flap can be swiveled within the fluid duct between positions with different degrees of opening; a swivel lever connected to the swivel axis, the swivel lever pivoting the swivel axis; an elastic working return element connected directly or indirectly to the swivel lever and applying a force to the at least one flap to return the at least one flap toward a home position; an actuating lever mounted to a housing part of the fluid duct configured to swivel around a rotation axis, the actuating lever mounted to the swivel lever swiveling round a connection axis; wherein the actuating lever has a working surface upon which the elastic return element applies a force to the actuating lever; wherein the rotation axis, the connection axis and the swivel axis are parallel to each other; wherein a distance radial to at least one of the rotation axis and the connection axis and between the rotation axis and the connection axis and/or between the swivel axis and the connection axis and/or the working surface and the connection axis and/or between the working surface and the rotation axis is varying dependent on the opening/closing position of the at least one flap.
