Easy Start Valve

I like the idea of the idle control,.I had thought about that in the past and I know they have been around for a long time,...I always liked the way a compressor will idle back when the system is pressurized. The issue I thought with doing this with a PW would be the washer would have to be using full pressure to make the idle control work and kick the engine back up to MAX RPM? I use big low pressure nozzles for house washing,..the only time I use any real pressure is with a rotating nozzle or surface cleaner.

Am I correct in my thinking on how this "idle down" function works?

*On a side note,.I don't see why using a ball valve to lesson the strain at start-up would hurt anything,..when it's open,..it would simply flow,....when it's shut,..it would be no different than the plug being in the outlet.

The only problem I can see with that is if you have a long run of hose say around the back of the house and the chem injector on. You would have it on concrete or somewhete where it wouldn't hurt any plants.

You just have to run really fast and beat the chemical!!!

Actually Al,..my chemical injector is controlled by remote control,..and only comes on when I command it to,..Ha,Ha,.. I've let the valve open sometimes over the past season to start the engine,.the worse thing it does is run 10 gallons of water out onto the ground. Sometimes I will place it strategically,.in a bucket for dipping a brush,..or in a flower bed.

I just don't like the the load on the starter and battery until the unloader reacts.

Jeff,

Once the psi on the high side of the unloader drops below 2000psi, the idle control releases and the system is pumped back up. It doesn't matter which nozzle(high or low) I have in the gun, once I pull the trigger, the idle control releases and the engine goes back up to whatever position I have the throttle set at.

I forgot to add, the idle control will only hold the engine at idle with a "no-flow" situation. As soon as you start flowing liquid, the idle control releases.

Does it use a pressure switch or a flow switch?
 
That and raising the idle rpms up a little work great for me. Due to upcoming surgery, I am down till around May, and in this time frame my trailer is torn down and starting from ground up with lots of upgrades. I have built a 12 channel remote controller to operate equipment and other items on trailer. I also built my own perportioning valves for high pressure (pressure washers) and low pressure ( roof cleaning with 100psi 7 glp pump. When I get all this done and complete and balanced, I would very much like to share this with all you guys wuth a private utube vidio. I have gathered and learned a lot of info from yall and would like to share back....If yall are searching for who this is, I have temporarily taken my website and facebook page down till I get back to work. I can be reached however at bill@multipressurewashing.com

That would be great! I always like checking out other people rigs.
 
Hello Michael, This sounds very interesting. Do you have pictures or schematics of this? Can this be added to any pressure washer out there? Sounds like it would save a lot of money each year in fuel savings alone. Thanks.
 
My system is a pressure actuated system. I will try to take a few pictures later on.

For a system like mine, you will need a trapped pressure unloader which has the wire harness connected to the bottom of the unloader body.

The fuel savings are fantastic. Using my system as an example, the machine has the black, round 8 gallon plastic fuel tank which Northern Tool had installed on their machines back in the early 2000's. If washing homes, 2500-3000 sq. ft., I can work all week and sometimes half of the following week without needing to refuel the machine.

The idle control will save on engine wear. When I start the machine, I open the auxiliary ball valve so I have open flow, set the choke, turn the key and as soon as the engine starts, close the auxiliary ball valve and the engine goes to idle speed. Allowing an engine to warm up at an idle is nice. In bypass, my pump is running at approximately 450 rpms.

Seems like of you used a flow switch instead of a pressure switch you could use it for low pressure stuff too?
But if you're using a downstream injector that wouldn't be necessary.
