Abstract
In a compressor comprising at least one traveling drum (4,4a,4b) rotatable about a drum axis (2), and an oscillation exciter supported in the drum (4,4a, 4b), the angular position of the oscillation exciter being adjustable by an adjustable pivoting angle relative to a vertical plane which extends through the drum axis (2), it is provided that the oscillation exciter comprises a pendulum-type vibrator (10) having a pendulum-type housing (8) which pivots about a pivoting axis extending coaxially to the drum axis (2) and includes a single unbalance exciter shaft (12) supported at a radial parallel distance to the drum axis (2) in the pendulum-type housing (8), wherein the pendulum-type vibrator (10) generates an elliptical drum oscillation.
