Abstract
An adjusting device of a compressor includes guide vanes (2) arranged in the form of a ring around a longitudinal axis (4), which vanes are in each case connected fixedly in terms of rotation to pivot pins (8) and are pivotally mounted in the housing (46). Two-armed cranks (10) are connected fixedly in terms of rotation to the pivot pins (8), cranks (10) neighboring each other in circumferential direction being linked to each other by means of coupling links (24, 26). With a lower overall volume and low use of materials, a jamming, in particular in view of thermal expansions and production tolerances, is to be avoided. For use with a radial-flow compressor, it is proposed to arrange the cranks (10) and the coupling links (24, 26) in an annular space (52) which neighbors the discharge port, into which space the pivot pins (8) parallel to the longitudinal axis (4) protrude with their free ends. All of the cranks (10) are arranged in a joint radial plane (53), the inner crank arm (14) being angled off with respect to the outer crank arm (12) by an angle (20) which is of the same size as the pitch angle (6). In this arrangement, crank pairs (28) are formed, the inner crank arms (10) of which are in each case angled off with respect to each other and the outer crank arms (12) of which are aligned in each case substantially parallel to each other.
