Hydraulic Cylinder Basics: Intro to the Parts of a Cylinder 

Much thanks. Some terminology used elsewhere is much clearer to me.

Nice presentation. Knowledgeable and interesting.

very good. that brings a lot of light into the darkness. but my single-acting cylinder still has a connection on the lower side for a fine, non-pressurized hose that goes back to the pump. could it be that this is a kind of emergency drain in case the piston seal leaks a little?

I have zero knowledge of Physics. Just looking for ideas to move a TV up and down by remote. Awesome eplanation. I can make a Physics degree now

Awesome!!! 🇺🇸🇺🇸🪓🪵🌲🪵🪓
