| 摘要 |
The present invention provides a flat jet nozzle for removing a material or soil using a high-pressure fluid jet within a pressure range exceeding 100 bar. A nozzle housing equipped in the nozzle housing forms a fluid duct with a discharge opening. A jet control unit is arranged in the nozzle housing. The fluid duct is formed concentric to a central longitudinal direction of the nozzle housing to the discharge opening. The discharge opening is formed into a lengthwise shape with a relatively long main shaft and a relatively short auxiliary shaft. A plane on which the relatively long main shaft is placed arranged perpendicular to the auxiliary shaft relatively short intersects with the central longitudinal shaft and forms an angle of 5-75, especially, an angle of 10-45 with respect to the central longitudinal shaft. |
