Abstract
The present invention relates to an actuation device for a compressor inlet adjustment mechanism. The actuation device comprises a housing part and a lever assembly. The lever assembly comprises a bearing section, an input section and an output section. The output section is configured to be coupled to an adjustment ring of the adjustment mechanism on a first side of the housing part. The input section can be coupled to an actuator rod on a second side of the housing part. The lever assembly is rotatably mounted in the housing part via the bearing section on the compressor inlet side here.
Claims21
An adjustment mechanism (200) for variable adjustment of a compressor inlet (22) comprising:
- a rotationally moveable adjustment ring (210);
- and
- a plurality of orifice plate elements (220) which are rotatably mounted and operatively coupled to the adjustment ring (210);
- wherein the adjustment mechanism (200) comprises an actuation device (10) comprising:
- a housing part (150);
- and
- a lever assembly (100) with a bearing section (120), an input section (110) and an output section (130);
- wherein the output section (130) is configured to be coupled to the adjustment ring (210) of the adjustment mechanism (200) on a first side (157) of the housing part (150) and in that the input section (110) can be coupled to an actuator rod on a second side (159) of the housing part (150), wherein the lever assembly (100) is rotatably mounted in the housing part (150) via the bearing section (120) on an inlet side of the compressor, and wherein an axis of rotation (22′) of the bearing section (120) is parallel to a compressor axis of the compressor inlet (22).
A method of assembling a compressor (300) comprising the following steps:
- providing a compressor housing (320);
- providing an adjustment mechanism (200) comprising:
- providing an actuation device (10) comprising:
- providing a housing part (150), a bearing section (120), an input section (110) and an output section (130);
- feeding the bearing section (120) through a bore (156) in the housing part (150);
- joining the bearing section (120) to at least either the input section (110) or the output section (130);
- and
- providing an assembly group consisting of a plurality of orifice plate elements (220) which are rotatably mounted and operatively coupled to an adjustment ring (210);
- and
- attaching the adjustment mechanism (200) to the compressor housing (320).
