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