<p>An exhaust butterfly in an exhaust conduit of an internal combustion engine is supported by way of bearing journals by positive plug-in connections. To simplify installation, the bearing journals and the bearing sleeves are designed in such a way that, to install the exhaust butterfly, the bearing journals are each pressed completely into the respective bearing sleeves counter to the force of a spring. In the case of a multiflow exhaust line, between adjacent exhaust lines cylindrical transverse passages are provided in each of which a driver is rotatably mounted. At one end, the driver has a recess which is designed as a bearing sleeve and into which the bearing journal of the first exhaust butterfly is inserted to produce a driving connection. The other end of the driver is designed as a bearing journal which is likewise inserted into a recess in the second exhaust butterfly to produce a driving connection.</p> |
