Load Sensing Accuracy 

Thanks for your suggestion. We've done just a little bit of work with grease systems. I believe it is inevitable that we will produce more material on that topic in the future, given all of the work we do with excavators and shovels. - Carl

Hydraulic generators can used on mobile equipment, I.e excavators, bachoe-loaders, crane trucks where engine speed varies, to power hand tools, water pumps etc. Generator can used normally even diesel running at idle speed. Search Dynaset.

We make all the software ourselves. You can read more about it here: www.carldyke.com/live-schematics

Carl, excuse me, do you use Scratch?

Scratch is a great tool for learning how to program, but it's not what we use. We have traditionally used Adobe Flash to make our animations, but we've now switched to creating animations that run in the web browser using JavaScript, HTML, CSS, and SVG.

You always need a restriction between the load and the pump for this style pump to work as it should. Not having a flow control, directional control, or restriction of some kind to backfeed a downstream signal to the flow compensator is the same as cutting the communication between the work hydraulics and the pump controller altogether. It is the same result as dumping the LS signal line and sending the pump into a neutral low pressure standby condition. There would be no reference pressure being fed back to the flow compensator telling it how to govern the amount of flow (swashplate angle) to apply against the load. The flow compensator would always open against a the light (i.e. 200-400PSI) compensator spring and send the pump into the low pressure standby condition and 0 displacement. You'd only get flow out of the pump when the load pressure fell beneath the flow compensator spring pressure, the margin pressure (i.e. 200-400PSI).
