Mr. Moulton patent from inside
60k km 'young' hydragas unit, worn because of manufacturing or design failure at Dunlop ??
Fluid sphere (bottom)
see the steel mesh :((
valve block ... shouldn't the fluid content a rust protection component???
piston hole for the knuckles boltpiston stud piston stud clamp in lower diaphragma
Nitrogen sphere (Top)
found parts from left to right:
Cut around the weld line, the non-return valve system . Again, very rusty steel parts. No wonder that they stick.
Nitrogen sphere side one valve, spring slipped a little bit to the right hand side
fluid sphere side (in the center is located a long rivet)
4 valves for back flow
1.0/1.1 weak spring, large diameter
2.0/2.1 strong spring small diameter
2 valves for fluid flow to the nitrogen pressure sphere
3.0/3.1 equal spring and diameter as No 2.0/2.1
Drawings of the spring and valve system follow. First
There are for each non return and damp accessing holes in the block. Closed by metal leave springs. The upper bended spring is surely weaker than the lower single leave. Springs have both functions. The damping of flow and transport of force to keep the holes closed.
Most confusing: The Valve block is sealed at its outer diameter by a O-Ring against the upper and lower sphere cap. That all means:
The caps welding together was done while the O-Ring and valve block is assembled between both caps and held under assemling force while the automatic WIG ?? welding was done. The welding line looks not like Laser or Electron beam welding...
