single action cylinder question(s)

[grsthegreat]

My kioti has a fill port adapter that has a standard hydraulic quick attach adapter, and there is NO pressure on the return line.

You mean have a loose line with an open end that gets stuffed back into the hydraulic fill port?

Hmmm…well sure, that would prevent the relief valve operating for a few seconds when lowering / retracting the cylinder, but wouldn’t you the have ~3000psi of hydraulic fluid dumping out the end of an open hose?

I wouldn’t want to be any where near it, even if I did anchor the end of the hose. I don’t know, is the GPM is low enough, even if the pressure is high, that this isn’t scary or dangerous? Or is the pressure low as long as it doesn’t meet resistance? IDK.

It's free flow going back to the tank. If there is no resistance in the flow path, there is no pressure.

Either way, I'm sure dicktill would do something more civilized than just shoving an hose through the fill port and having the fill port open to the elements.

: ) .... and thanks for the replies

Yes, I would tee that line into another return line.

Yeah…now that I think about it for 2 seconds, that is how every return line to fill port works.
