<p>A jet pipe for the supply of hot gases formed with a double wall for the passage of cooling means, and where the jet pipe has a longitudinal axis, includes a throttle valve which may be rotated about an axis transverse to the jet pipe longitudinal axis. The jet pipe may be partitioned along a plane including the axis transverse to the longitudinal axis. The jet pipe includes a first segment disposed ahead of the partition plane, and a second segment disposed behind the partition plane. The first and second segments serve for circulation of the cooling means, and are separated from one another.</p> |
