ABSTRACT:
An improved driving linkage device for adjusting a variable nozzle mechanism in a supercharger turbine or a variable diffuser mechanism in a compressor. The driving linkage device is provided with a driving ring for driving a variable nozzle mechanism in a supercharger turbine or a variable diffuser mechanism in a compressor, one or more sets of adjusting links, each set consisting of three levers connected in a U-shape and having two opposed ones coupled to the driving ring and a fulcrum for supporting the lever not coupled to the driving ring. One end of one adjusting link is coupled to an actuator to achieve the adjustment of a variable nozzle mechanism in a supercharger or of a variable diffuser mechanism in a compressor.
