본 발명은 기체와 액체를 통칭하는 유체를 분사하는 유체노즐에 관한 것으 로, 더욱 상세하게는 노즐팁의 전방 내부에 콘 형상의 소음기를 구성하여, 상기 소음기를 통해 유체가 분사되면 소음이 현저히 억제되고, 상기 소음기의 외주연에 형성된 나선형의 가이드홈에 의해 분사되는 유체가 시계반대방향으로 와류분사되어 공구로 공작물을 가공할 시 발생하는 시계방향으로 회동하는 공기막과 혼합이 용이하며, 상기 소음기 후방에 볼을 구성하여 유니언파이프가 노즐팁에 나사결합되는 간격에 따라 분사유량을 미세하게 조절할 수 있는 유체 분사노즐에 관한 것이다.The present invention relates to a fluid nozzle for injecting fluids collectively referred to as gas and liquid, and more specifically, to a cone-shaped silencer inside the front of the nozzle tip, when the fluid is injected through the silencer, noise is significantly suppressed. The fluid injected by the spiral guide groove formed in the outer periphery of the muffler is vortex sprayed counterclockwise to facilitate mixing with the clockwise rotating air film generated when the workpiece is processed by the tool. The present invention relates to a fluid injection nozzle capable of finely controlling the injection flow rate according to the interval at which union pipes are screwed to the nozzle tip.

지금까지의 기체와 액체를 분사하는 유체 노즐에서, 유체 통로의 직경 및 상응하는 유동 단면적은 분무 물방울의 크기 분포에 영향을 미친다. 유체 통로가 미세할수록 분무 물방울이 미세하게 형성된다. 따라서, 공지된 유체 스프레이 노즐에서는, 분무 물방울의 평균 크기를 감소시키고 또한 미세 분무 스프레이를 형성하도록 통로의 직경이 감소하였다.In the fluid nozzles injecting gases and liquids up to now, the diameter of the fluid passage and the corresponding flow cross-sectional area influence the size distribution of the spray droplets. The finer the fluid passage, the finer the spray droplets are. Thus, in known fluid spray nozzles, the diameter of the passageway was reduced to reduce the average size of the spray droplets and to form fine spray sprays.

하지만 노즐의 직경이 감소한 만큼 분사할 시 유체가 노즐에서 빠져나가는 저항이 커 소음이 심하게 발생하였다.However, as the diameter of the nozzle was reduced, the noise was generated because the resistance of the fluid to escape from the nozzle was large.

그리고 종래의 노즐은 유체를 분사할 시 방사형으로 분사되었는데, 일반적으로 공작기계에 의해 구성되어 공작물을 가공하는 공구는 시계방향으로 고속회전한다.In addition, the conventional nozzle was radially sprayed when the fluid is injected, the tool which is generally constituted by a machine tool to process the workpiece rotates in a high clockwise direction.

이때 상기 고속으로 회전하는 공구에 의해 공기막이 형성되어 가공시 공구와 공작물의 마찰을 줄이고, 공구를 냉각하는 절삭유의 침투가 어려워 그 기능을 제대로 실행하지 못하는 문제점이 있었다. At this time, the air film is formed by the tool rotating at a high speed to reduce the friction of the tool and the workpiece during machining, it is difficult to penetrate the coolant to cool the tool has a problem that does not properly execute the function.
