Definitions
- the invention relates to an arrangement for controlling a variable position of vanes in a flow channel of a turbine according to the preamble of claim 1.
- the invention furthermore relates to a turbocharger for an engine including a turbine rotatably mounted on a shaft, a compressor impeller mounted on a shaft, a compressor housing having an inlet and an outlet and enclosing said compressor impeller, a center housing including bearing means for rotatably supporting the turbine shaft and compressor shaft, a turbine housing including an inlet and an outlet, said turbine housing forming a volute therein for directing exhaust gas from said engine through an annular passage to said turbine, and a flange member mounted between said center housing and said turbine housing, which turbocharger further includes an arrangement for controlling a variable position of vanes at a turbine inlet.
- the invention also relates to an engine including a turbocharger unit.
- Supercharged diesel internal combustion engines used in commercial vehicles are frequently equipped with turbochargers with variable inlet geometry such to adjustably set the effective turbine cross section. This is accomplished by adjusting the angular position of a set of vanes being arranged in an annular passageway in the turbine housing.
- the annular passageway is connecting the scroll shaped volute defined in a turbine housing to a turbine chamber where a turbine is located.
- Each vane is connected to a vane pin housed in a nozzle ring.
- the vane pin is connected to a vane arm which connects the vane pin with a unison ring. Pivotal movement of the unison ring enables simultaneous pivoting of the vanes in the annular passageway.

- the second actuator arm being connected to the unison ring via the pin enables pivoting of the unison ring around its rotational axis.
- a stop screw is used.
- the stop screw delimits the movement of the first actuator arm by defining an end stop in one of its positions.
- Two stop screws may be used variably defining respective end position of the vanes. Since the end position corresponding to a minimum throat area defined by the vanes requires the most precise positioning, it may be sufficient to use a stop screw for this position, while the other position may be defined by the actuator or a fixed end stop.

- a seating for the stop screw in the flange member or in the turbine housing, depending on the actual configuration of the turbine housing and/or the flange member.
- the turbine housing and the flange member are normally cast members.
- the position of the seating for the stop screw can thus be manufactured with high requirement on the tolerance at low cost in comparison with the current practice to arrange a mounting bracket on the flange member. Mounting of mounting brackets can normally not be made with a high precision at low cost. Furthermore, the brackets themselves add to the tolerance by their low rigidity and added play.
