Re: CAT330D-L full hydraulic
@avel, yes, exactly. In the video you can see when the valve is in the center position system pressure and current drain drastically decrease. In this condition the pump does not wear and produce the minimum of the heat, nevertheless the overall efficiency increase and so the autonomy become longer. In the center position with the MiMh 10 cells battery i have chosen the system can run hours and hours.
@rvjimd, the brass and copper tubes are not much simple to bend, but with some tools it's possible. I use some little metal wheels with the radial section of the same radius of the tube you have to bend. Next time i show you some photos.
Enrico.
