A while back, I had a problem with my compressor, >> Here <<
While I got the new part, and installed it, the problem was NOT solved
To be honest, I was fed up with it, and just turned the darn thing off
I was working on the ill fated >> FREE << compressor, and I noticed that it did not have the release valve thing, maybe because it is only a single piston type, and the troublesome compressor is a double piston unit
Then, I was reading through Vaughn's thread about his >> Air Line System << and when I read the bit about the one way valves, and my puny little brain started to work.....
What was happening, the trouble, was the compressor would run up to max, and then shut down. The bleed valve would open, and it would not shut. What the bleed valve does, as far as I know, is to bleed the pressure out of the two pistons, so when the compressor starts up again, there is NO built up pressure in the cylinders, making it easier when the motor kicks in.
What I realized, is that there must be a one-way valve between the compressor pumps and the storage tank, and it must not be working right.
Yep, that is what it was.......
That is it, I got it apart, and the valve was somewhat blocked with stuff, also I found the rubber was hard,and shinny, plus, there was a circular impression where the valve contacted the rubber seal. I took a piece of #240 PSA sandpaper and stuck it on a bit of plywood, then I carefully sanded the face of the rubber seal until the circular shaped impression was gone. Now the compressor works just like it was supposed to!
Thing is, I wonder where I'll find another rubber seal, as the sanded one may last a while, but it will have to be replaced at some point.
I'm real happy this is fixed, but I have to say, I'm kind of kicking myself for not figuring it out soon.....
