Abstract
A valve guide arrangement for a valve in a bypass or shunt duct of exhaust gas ducting equipment of naturally induced or supercharged engines, in which arrangement the stem of the valve is caused to slide in a valve guide formed as a bush and fixed rigidly in a housing part and an annular space is provided under the valve guide and surrounding the valve stem and operating as a settling space, this annular space being connected with the bypass or shunt duct by means of an annular gap operating as a throttle and formed by the valve stem and the housing part. The object of this special valve guide arrangement is to prevent valve jamming due to the solid exhaust-gas constituents found in the exhaust gas flow.
