Abstract

A method and a device for orienting an actuator of an exhaust-gas turbocharger which has an actuator that is equipped with an actuator housing and is connected to a control rod. First, an actuator holder is fastened to the compressor housing of the exhaust-gas turbocharger. Then the actuator is inserted into the actuator holder. Then the actuator is positioned within the actuator holder. Then a compensating material is introduced through an injection opening into a compensating-material receiving space which is provided in the actuator holder. Finally, the compensating material is hardened.

First claim

The invention claimed is:

1. A device for orienting an actuator of an exhaust-gas turbocharger, comprising:
an actuator provided with an actuator housing;
a control rod connected to said actuator;
an actuator holder disposed to support said actuator housing with a spacing distance between said actuator housing and said actuator holder forming a compensating-material receiving space between said actuator holder and said actuator housing;
said compensating-material receiving space being formed to extend annularly around said control rod and an end region of said compensating-material receiving space radially inside being spaced apart from said control rod; and
a compensating-material injected into and hardened in said compensating-material receiving space to compensate an actuator displacement in a direction of the rod axis.

2. The device according to claim 1 , wherein said actuator housing has a cover and a lower part, said spacing distance formed between said actuator housing and actuator holder being formed at said lower part of said actuator housing, and said compensating-material receiving space is formed between said lower part of said actuator housing and said actuator holder.

3. The device according to claim 2 , wherein said lower part of said actuator housing includes a bottom part and a counterholder disposed between said actuator housing and said actuator holder and fastened to said bottom part of said actuator housing, and wherein said compensating-material receiving space is formed between said counterholder and said actuator holder.

4. The device according to claim 1 , wherein said compensating-material receiving space has an injection opening.

5. The device according to claim 1 , wherein the compensating material is a polymer resin.

6. The device according to claim 1 , wherein a position of said actuator in said actuator holder can be changed when said compensating-material receiving space has not yet been injected with the compensating material and the position is fixed after the compensating-material receiving space is injected with the compensating material and the compensating material has hardened.
