| 发明名称 | 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′). | ||

| 主权项 | 1. A Laval nozzle (10) having a flow channel (12), which has a flow cross-sectional profile (14) extending in a convergent-divergent manner, the flow channel (12) comprising two 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, and also comprising two mutually opposite second flow channel walls (20, 20′), which are movable relative toward one another or away from one another for adjusting the flow cross-sectional profile (14) of the flow channel (12), wherein the second flow channel walls (20, 20′) are disposed between the nozzle bodies (18, 18′), wherein the nozzle bodies (18, 18′) are cylindrical and are disposed coaxially and one inside the other, and wherein mutually facing surfaces (28, 28′) of the nozzle bodies (18, 18′) have a fixed Laval contour along the flow channel (12). | ||
