Abstract
The axial bearing arrangement comprises a first axial bearing plate (12) and a second axial bearing plate (13) each having an annular ring shape, the first axial bearing plate (12) having a first surface (12.1) axially facing the second axial bearing plate (13) and a second surface (12.2) opposite to the respective first surface (12.1), the second axial bearing plate (13) having a first surface (13.1) axially facing the first axial bearing plate (12) and a second surface (13.2) opposite to the respective first surface (13.1); a spacer ring (14) clamped between the first surfaces (12.1, 13.1) of the first and second axial bearing plates (12, 13), the spacer ring (14) defining an axial distance between the first and second axial bearing plates (12, 13); and a bearing sleeve (15) abutting the second surface (13.2) of the second axial bearing plate (13) and being secured to a compressor block (16). The axial bearing arrangement includes an elastic element (22) axially biasing the first and second axial bearing plates (12, 13) and the spacer ring (14) with a predetermined force against an abutment surface (17) of the bearing sleeve (15).
