It is quite simple, the hydraulic oil reservoir is a hp tank that can be pressurized from a designated HP supply. The oil return goes to another HP tank to receive the oil. This eliminates the pump completely and that is a dream. The manipulator can go through 54 complete extensions and retractions, that is 54 complete movements of all functions. </div><div dir="ltr" id="yiv7584996133m_-9191931575658324426yui_3_16_0_1_1480075807070_2825">After the oil is used up, the oil can be returned to the pressure tank by reversing the air flow.</div><div dir="ltr" id="yiv7584996133m_-9191931575658324426yui_3_16_0_1_1480075807070_2825">Hank</div></div></div></div><br clear="none">______________________________ _________________<br clear="none">
