Thanks for the info (sounds like an advertisment / press release?). Anyway, I was sctually looking for info on how the flow in the actuators is varied, and this is basically answered by "the help of magnetic valves". Didn't know that magnetic valves have responce times of milliseconds - they must be pretty high tech (super fast & very precise)...

this physically happens by way of a motor altering the size of the hydraulic channel.

the magnetic systems in use utilize metallic particles in the fluid, when these systems are actuated, an electric current (up to 5 amps per corner) causes the metallic fluid to become more viscous and thereby limiting the flow through the orifice. these operate 1/1000 of a second or
Thanks. Here we have (a) a motor altering the size of the hydraulic channel (or the crossection of an orifice maybe?), and/or (b) a magnetic system embodying variable viscosity fluid. (b) sounds pretty impressive (star trek technology?), but which of they two is it? Or is it a combination of both?

BTW, what happened to you in the end? RBV kicked in suddenly, wife / gf stepped in?
