Variable or adjustable what ever you call them, what are they, & what do they do?

The Adjustable Nozzle:
Variable, adjustable or high-low what ever you wish to call them, what are they, & what do they do?

This topic was brought up to me the other day. I had a hard time explaining it but I think I got the point across. How they work why they work is not that important but I give it a try once again. 

The adjustable part is fairly straight forward, you once again have to match the nozzle to the out put of your machine. Once you have the correct size or orifice you have half the problem licked. The opening in the nozzle is for all practical prosperous a 0* nozzle matched to your machine. We all know what can happen with a 0* nozzle so be careful. What these "adjustable" nozzles now can do is change that 0* stream exiting the nozzle to a fan pattern. Below are a few of the nozzles I have and have them pictured closed and opened. When open they are equal to a 0*. Depending on the manufacturer when closed they can be up to an 80* fan pattern. By twisting it from side to side you are pushing the two stainless steel blades tighter together making a fan. The wider the fan the softer the pressure same as your fixed nozzles.

We can now see what make the fan and why it works. It is just a simple device that pushes and holds the blade in a position the tighter the blades the wider the fan.

There are several types and styles of these "adjustable or variable" nozzles each is different and each has a place in my tool box.

One of Cleaned by Pete's variable, adjustable or high-low nozzle, this one happens to also be a turbo nozzle.

By truing the adjuster the water is forced out of the holes in the bottom of the bell reducing the pressure into the center. This nozzle can also be turned down low enough to draw soap from an injector.
Some of these nozzle are also able to change form low pressure to high pressure by pushing it forward for low pressure and pulling it back for high pressure usage. Sometimes called a push-pull nozzle. This is done by opening a low pressure zone behind or inside the nozzle causing it to now draw soap viva the injector at the pump or as pictured above at the nozzle itself.
This adjustable high-low push-pull is also called a M5-z-jet style of nozzle. Push it forwards will draw soap in a fan or twist is to shoot soap in a stream. Pull it back high pressure returns 80* fan to 0* stream.
If you need a custom fan to fit your work then you can use these nozzles to create that fan pattern. If you need to change it just twist. No need to have a pocket full of nozzles. I have a place and use these nozzles on jobs while I still use the quick change standard nozzles your green, yellow, and white I still have a need for this style of nozzle on certain jobs.

One last mention here is my adjustable water cannon while it is a gun it does the same thing by moving the handle forward it is a low pressure gun to draw soap pulling it backwards it becomes high pressure again and anywhere in between.
