Definitions
- the invention relates to a spray nozzle with an outlet opening to form a liquid jet and with an in Flow direction arranged behind the outlet opening Baffle to create a spray fan.
- Flat jet nozzles which have a liquid jet spray on a flat baffle to create a substantially to create flat spray fans.
- approximately circular-cylindrical Refinements to shield against detection with Infrared systems with a circular or circular segment Liquid screen should be covered.
- the known flat jet nozzles are not necessarily suitable, because with them only polygon-shaped spray patterns Can be realized using multiple nozzles.
- Such Flat jet nozzles also have strong edge jets and as a result a very uneven distribution of the liquid across the width of their fan.
- the present invention is therefore based on the object to design a spray nozzle of the type mentioned in the introduction, that roughly circular or segmented spray fans can be generated.
- This configuration means that the liquid on the convexly curved baffle occurs and its curvature accepts. This creates a semicircular liquid curtain with even liquid distribution.
- the baffle is under one Angle of attack to the axis of the exiting from the outlet opening Liquid jet turned on. This angle of attack determines the spray angle and the spray distance.
- the width the tongue can move in the direction of the liquid jet expand so that a particularly good fan-shaped The spray jet is divided.
- the angle of attack and the convex curvature were chosen so that the desired shape of the semicircular liquid curtain is achieved.
- Fig. 1 shows that the new spray nozzle 1 with a connector 2 for supplying a liquid inside a housing 3 is provided.
- This housing 3 has one Outlet opening 4 from the inner chamber 5 (Fig. 2) is led to the outside.
- the outlet opening 4 sits on End of a narrowing channel from chamber 5, the Axis 6 the direction of the emerging liquid jet certainly.
- baffle 7 in the liquid jet being formed protrudes.
- the on the convexly curved baffle 7th impinging liquid becomes a convex radius Baffle 7 modified fan beam shape.
- the shape of this fan is roughly semicircular and this fan 9 is clearly too in FIGS. 3 and 4 detect.
- Fig. 3 shows that the spray nozzle 1 in itself can be installed in a known manner in a wall 11. Fig. 3 also shows that the initially emerging approximately circular-cylindrical Liquid jet 12 when hitting the impact surface 7 is expanded and then the curvature of the assumes convex baffle 7.
