LAVAL NOZZLE

摘要

In a Laval nozzle (10) having a flow channel (12), which has a flow cross-section (14) extending in a convergent-divergent manner, according to the invention the flow channel (12) comprises mutually opposing first flow channel walls (16, 16`), which are formed by two nozzle bodies (18, 18`) spaced a fixed distance apart from one another. Two mutually opposite second flow channel walls (20, 20`), which can be moved relative toward one another or away from one another for adjusting the flow cross-section (14) of the flow channel (12), are disposed between the nozzle bodies (18, 18`).
