  • VNT flow calibration adjustment
    Patent number: 8122716
    Abstract: An exemplary variable geometry turbine includes a turbine wheel; a variable geometry assembly that includes a rotatable control ring that has a slot and a plurality of vanes where each vane has a post pivotably controlled by rotation of the control ring and where adjacent vanes define nozzles to direct exhaust gas to the turbine wheel; a crankshaft that has a pin for receipt by the slot of the control ring where rotation of the crankshaft rotates the control ring; and a center housing that includes a rotatable stop fixed to the crankshaft and having a close stop surface, a secure component and a translatable shaft where the translatable shaft comprises an engagement mechanism to engage the rotatable stop; where translation of the shaft causes rotation of the crankshaft and where the close stop surface establishes a contact with the secure component to limit rotation of the crankshaft and to establish a closed limit for the vanes. Various other exemplary methods, devices, systems, etc., are also disclosed.
