The invention discloses a spraying device for applying friction modifying fluid on a railway track. The spraying device comprises a nozzle body arranged in a shell; a fluid inlet conduit in fluid communication with the opening of the housing; a fluid inlet disposed in the housing, the fluid inlet in fluid communication with a first fluid conduit defined by or disposed in the nozzle body; wherein the first fluid conduit extends from the fluid inlet to a hollow nozzle head body disposed on and protruding through the bottom of the housing; a control fluid supply conduit and an atomization fluid supply conduit each partially disposed in the housing; wherein the control fluid supply conduit ejects a pressurized control fluid onto a piston assembly disposed in a piston chamber; wherein the piston assembly has a stop needle which is biased towards the hollow nozzle head body by a spring such that the needle closes a nozzle head opening of the hollow nozzle head body.

    本发明公开一种用于在铁路轨道上施加摩擦改性流体的喷涂装置,包括:设置在壳体中的喷嘴本体;与壳体的开口流体连通的流体入口导管;设置在所述壳体中的流体入口,所述流体入口与由所述喷嘴本体限定的或设置在所述喷嘴本体中的第一流体导管流体连通;其中所述第一流体导管从流体入口延伸至中空喷嘴头本体,所述中空喷嘴头本体设置在壳体的底部上并穿过壳体的底部突出;控制流体供应管道和雾化流体供应管道,其各自部分地设置在壳体中;其中所述控制流体供应管道将加压的控制流体喷射到设置在活塞腔中的活塞组件上;其中所述活塞组件带有止动针,所述止动针通过弹簧偏向中空喷嘴头本体,使得所述针关闭所述中空喷嘴头本体的喷嘴头开口。
