Re: [CAD_CAM_EDM_DRO] Automatic Lubricator

Hi,

My understanding of a manifold system means one pump feeding a distribution
point and flow control is achieved via orifice sizing. Too much maths for
me. I can cope with volumes and revolutions :-)

The idea I have is to have a central reservoir alongside the piston block.
Each piston cylinder would have a light spring loaded ball so that oil could
not flow back into the reservoir. As the piston rises it draws oil from the
reservior. The piston would also have a spring to keep it against the
camshaft. Oil would exit via a none return spring loaded ball into a small
tube to feed the desired point. I have boxes of springs and 3/16" balls.

Some pistons would only pump once an hour while others, with more lobes on
the cam, could pump up to six times an hour; for instance feeding the
leadscrews. Although with more lobes the stroke would be shorter.

I have a number of powerful'ish 12 volt DC motors, with I removed encoders
from, which could be massively geared down and also a simple motor speed
control.

If the cam could be move away from the piston block to unload the pistons
then levers could be mounted bearing on the pistons so that manual oiling of
each point could be done before start up. None return valves could also be
provided close to the oiling point so that it takes positive pressure and
the system won't drain-down when idle

Terry
