Abstract
A guide device with adjustable guide vanes is provided with a drive for the adjustable guide vanes, in which a cylindrical driving pin and an adjusting lever are provided each with one surface pair which are matched to one another and which slide on one another in operation when the guide vanes are being adjusted. To adjust the guide vanes, the adjusting ring is moved, by which the driving pin attached to the adjusting ring slides in an elongated groove of the adjusting lever and applies a force to the adjusting lever. This approach yields an economical and durable structure which is easy to install. This results in surface support with the corresponding low compressive loads per unit area and consequently greatly reduced wear.
