[SEL] Diesel Engine Starter With Oil Pump, turbo accumulator

[Richard Strobel]

yea Ron..accumulators have a piston of somwhat..and do requre a precharge on 
the non-engine side of the accumulator piston..when the engine oil pressure 
drops, the precharge pushes the piston thusly suppling lubricant to what 
ever.

Widely used in the hydraulic field

Solly on the MH..just sold mine..best thing I ever did
