Abstract
An integral workpiece which has a duct located within a region which extends, for example in an annular manner, and formed about an axis of the workpiece. The workpiece has a form-fitting connection by which, when viewed in a cross section extending through the axis, the duct is closed. The form-fitting connection enables, in comparison with known manufacturing methods, particularly simple manufacturing of the workpiece. In particular, no welding or screwing is required for closing the duct.
