## Abstract

A compensator arrangement comprising a first fixing unit, a second fixing unit, and an intermediate flexible member removably arranged between the first fixing unit and the second fixing unit and comprising a main body, a first radial end flange and a second radial end flange, wherein the first fixing unit comprises a first connecting member having a first connecting body and a first fixing flange having a plurality of through-holes, a first counter ring, a first clamping ring and a first clamping device for releasably clamping the first radial end flange.

## Claims

### Claim 1

A compensator arrangement comprising:
a first fixing unit,
a second fixing unit, and
a flexible intermediate member detachably arranged between the first fixing unit and the second fixing unit and including a main body, a first radial end flange and a second radial end flange,
wherein the first fixing unit includes a first connecting member having a first connecting body and a first fixing flange having a plurality of through-holes, a first counter ring, a first clamping ring and a first clamping device for releasably clamping the first radial end flange, the first clamping device comprising bolts and elongated recesses for receiving the bolts,
the second fixing unit includes a second connecting member comprising a connecting body and a second fixing flange having a plurality of through-holes, a second counter ring, a second clamping ring and a second clamping device for releasably clamping the second radial end flange, the second clamping device comprising bolts and elongated recesses for receiving the bolts,
wherein the first end flange of the flexible intermediate member is fluid-tightly clamped between the first fixing flange of the first connecting member and the first counter-ring,
wherein the second end flange of the flexible intermediate member is fluid-tightly clamped between the second fixing flange of the second connecting member and the second counter-ring, and
wherein the first connecting member comprises a circumferential axial projection projecting in the axial direction on an inner side of the fixing flange, wherein the flexible intermediate member is clamped between the axial projection and an inner edge of the first counter ring in the mounted state.

### Claim 2 (depends on 1)

The compensator arrangement according to claim 1, wherein the bolts comprise a head.

### Claim 3 (depends on 1)

The compensator arrangement according to claim 1, wherein the flexible intermediate member is made of a flexible plastic material.

### Claim 4 (depends on 1)

The compensator arrangement according to claim 1, wherein the bolts are arranged on the first counter ring and on the second counter ring.

### Claim 5 (depends on 1)

The compensator arrangement according to claim 1, wherein the bolts are threaded bolts.

### Claim 6 (depends on 1)

The compensator arrangement according to claim 1, wherein the elongated recesses comprise ramps which are inclined towards a radial plane.

### Claim 7 (depends on 6)

The compensator arrangement according to claim 6, wherein the ramps are laterally arranged on the elongated recesses.

### Claim 8 (depends on 1)

The compensator arrangement according to claim 1, wherein the elongated recesses are arcuate or rectilinear.

### Claim 9 (depends on 1)

The compensator arrangement according to claim 1, further comprising indicator means for determining a predetermined end position of first and second fixing units in the assembled state.

### Claim 10 (depends on 1)

The compensator arrangement according to claim 1, the first and/or second connecting body comprising a cylindrical cross-section or a polygonal cross-section.

### Claim 11 (depends on 1)

The compensator arrangement according to claim 1, the first and/or second connecting body comprising a square cross-section.
