ABSTRACT:
A turbine housing of an exhaust gas turbocharger with a variable turbine geometry is provided, having a support ring to which vanes are fastened which are adjustable for controlling the charge pressure, and having a covering ring for the vanes. The support ring and covering ring are spaced for forming a vane gap by spacing elements which are each penetrated by a holding element which is fastened in the support ring and/or the covering ring. The spacing elements have recesses which, during the operation of the exhaust gas turbocharger, permit a direct action of the exhaust gas flow upon the holding elements.
