Abstract
A variable turbine geometry may have a blade bearing ring and guide blades, each rotatably mounted therein via one of a plurality of respective blade bearing pins. An adjusting ring for adjusting the rotary position of the guide blades may be arranged on a side of the blade bearing ring facing away from the guide blades. The cover disc may define through-openings aligned with the blade bearing pins of the guide blades. The blade bearing ring may define at least one channel configured to create a pressure equalization between the control space and the flow space.
