摘要： A motor-driven throttle valve (1) for an exhaust duct and having: a tubular duct (2), which is designed so that exhaust gases can flow through it; a throttle shutter (3), which is arranged inside the tubular duct (2) and is mounted so as to rotate around a rotation axis (4); a first shaft (5), which is mounted so as to rotate around the rotation axis (4) and supports the throttle shutter (3); an electric actuator (6), which is provided with a second shaft (52) and is designed to rotate the shaft (5) around the rotation axis (4); a support bearing (9), which supports the shaft (5) in a through manner and is arranged on the outside of the tubular duct (2); and a spring (11), which applies to the shaft (5) an elastic force, which axially pushes the shaft (5) and, at the same time, is configured to transmit a rotary motion around the rotation axis (4) from the second shaft (52) of the electric actuator (6) to the first shaft (5) supporting the throttle shutter (3).
