Throttle valve for internal combustion engines

A throttle valve (38) may comprise a valve body (60) providing a main gas path, a throttle shaft bearing (72) integrated in the valve body (60), a pivotable throttle shaft (64) mounted to the valve body (60) via the throttle shaft bearing (72), a throttle plate (66) mounted to the throttle shaft (64) and being pivotable within the main gas path by pivoting the throttle shaft (64). The throttle valve may further comprise a channel system (70) integrated into the valve body (60) and configured to guide a high-pressure gas to the throttle shaft (64) for then flowing along the throttle shaft (64) into the main gas path. The throttle valve (38) may be used to control an exhaust gas flow within the exhaust system of an internal combustion engine (10) and allows protecting the throttle shaft bearing (72) from the exhaust gas and its components such as soot.
