Two vibration absorbers (30.1,30.2) are so mounted on the compressor (21) that their oscilllating masses (38.1,38.2) vibrate vertically or at 45[deg] to the axis of the free exciter moment resulting from the compression operation and the masses in movement. Absorber (30.1) is on the compressor as against aborber (30.2) which is on the motor side through both absorbers lie on the same side of the compressor in relation to the axis of rotation and can be arranged at any point round the circumference. Absorber (30.2) is preferably offset 180[deg] to the rotation axis. The absorber masses (38.1,38.2) are supported towards the compressor housing between two compression springs (34.1.1,34.1.2,34.2.1,34.2.2) with the masses offset rouind 180[deg] of the housing circumference. The absorbers include ball-, roller- or needle bearings for mass guidance. |
