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.
Claims10
A turbine housing of a variable turbine geometry exhaust gas turbocharger with an adjustable turbine geometry, comprising:
- a support ring to which charge pressure-adjusting vanes are fastened;
- a covering ring;
- spacing elements;
- and
- fastening elements,
- wherein
- the support ring and the covering ring are spaced apart by the spacing elements,
- the spacing elements are each penetrated by one of the holding elements,
- the fastening elements are fastened to at least one of the support ring and the covering ring, and
- the spacing elements have recesses which, during the operation of the exhaust gas turbocharger, permit a direct application of an exhaust gas flow upon the holding elements.
