I am new to hydraulic priciples, and have read some great tutorials that have been linked here. I noticed that on a Sunstrand inline hydrostatic transmission, there is a need for a charging pump due to cavitation. Is this because that the case serves as the resevoir ? Is air entering the line because the case cannot be filled completely ? It seems if I am correct the same components running seperately , with a seperate reservoir have no need for a charge pump.
I should never started studying hydraulics ! Its like a drug ! I find myself mulling over questions all the time now, like a child, why? why ? why ?
Thanks for taking the time to read guys !
sorry for the edit, I was wondering if it could be due to the res not being higher than the pump, no flow to the pump.
