Hi All,

Before I head off into deep design, I was wondering if anyone could point me in the direction of either an off the shelf product or a published design for an adjustable nozzle for spraying water based liquids.

I am looking for something in the same style as the slightly old-fashioned hand held garden hose spray – where it is possible to go from a fine mist spray through to a straight jet of water by a simple twist of the nozzle body.

It actually needs to be rather smaller than a hose size – more the scale from a small pump up garden spray.

Operating pressure is likely to be in the 6-10 Bar range, although probably nearer the lower end of this range.

The key point is that it needs to be remotely controlled by a servo-like arrangement – so, as an example, turning a pot causes the output to go from spray through to jet – or stop somewhere mid point.

The rest of the technology either exists or will be designed/bought to match this part.

If necessary, I will rig up something from a combination of R/C servos and bits of garden watering systems, etc but it would be useful if somebody has already invented the wheel!

All thoughts gratefully received…..

Simon
