摘要：
A nozzle includes first guiding elements (10) circumferentially arranged at a nozzle rim (9). To reduce sound emission while keeping flow losses low, second guiding elements (20) are also circumferentially arranged at the nozzle rim (9), with one of the first and second guiding elements (10, 20) being diffuser-type and the other of the first and second guiding elements (10, 20) being nozzle-type and with both types of guiding elements circumferentially alternating with each other.
