Abstract

A connecting device is provided between a turbine housing of an exhaust turbocharger and an exhaust manifold housing of an internal combustion engine. The turbine housing and the exhaust manifold housing are kept in position via a band clamp which acts with first and second limbs, which are oriented in a V shaped manner in cross section and are connected via a web, on supporting devices, which are attached to outer circumferences of the turbine housing and of the exhaust manifold housing, and are configured in the manner of first and second ring flanges placed on each other, such that, firstly, first and second clamping surfaces of the limbs are operatively connected to third and fourth clamping surfaces of the supporting devices on first and second connecting planes, and, secondly, first and second radial supporting surfaces are operatively connected to each other on a supporting plane of the supporting devices. An intermediate ring is effective between the second clamping surface of the second limb and an inner supporting surface of the second edge flange. The intermediate ring is clamped against the inner supporting surface of the second ring flange via the second and fourth clamping surfaces and a clamping surface portion of the intermediate ring.
