Abstract (en)

[origin: EP1111196A2] The device has a rotor wheel in a housing enclosed by at least one flow channel with an annular nozzle opening onto the rotor wheel and at least one variable control grid with control blades and grid channels. The effective annular nozzle flow cross-section is adjustable using a grid adjuster. An adjuster (14,15) is used to vary the width of the gap between the control grid (11) and the enclosing housing wall parts (10) between maximum and null. Independent claims are also included for the following: an adjustable control device for a turbocharger's exhaust gas turbine.
