Hydraulic Motor Temperature

Hey Lil Giants,
I'm not a hydraulic engineer, but the spool design makes a big difference in how a valve perform's. The relief valve shouldn't be used to unload the pump in the first place. They could just build a real "open center" valve, solve the problem. Yes I know it's more work to build an open center valve. What's my point, The German's half A$$ed there design! And Yes I base my experience from the 1:1 side, and have alot to learn on the rc side of the fence. Reinvent the wheel, not quite, Just use some of the full size trick's, that I've been learning from Brendan Casey, and down size them. I'm sure we have enough machinist's on this forum to beat the German's at there own game!!!!!!!
With time and money, I want to play with the cnc stuff too!!

P.S. that Hitachi run's smoother than my full size Cat 305CCR!

Hey pug's, the simplest idea, I've had so far is reed switch's and magnet's glued to the servo horn's, for a controller. Not perfect but very simple, kinda like the electric forklift's that start the hydraulic pump after the lever has moved slightly. Each lever has a micro switch attached to it, for pump control. I'll put my soap box back in the dungen. Later, Neil#2 aka doodlebug

Actually , open ( Constant ) flow hydros have been around for some time . And is not hard at all to accomplish . just a mater of a little more machine work on the valve and plumbing . But bear in mind , We're using electric motors to run the pumps ,not IC motors where we fill the fuel tank and run a whole day . No mater what way we plumb these systems you do not want the pump running any longer then needed hence short batt life on long periods of run time . Now the constant flow would reduce the strain on the pump .

Wow Neil #2 I thought the 305 was pretty smooth , Well , compared to a Koering 6605 non- pilot control

There are a lot of you expert machine guys out there and I, for one, would be onboard to invest in a simplier design. This thread has generated a lot of helpfy information. Has anyone seen this design?
