Copy to Na.{Mr Nadin} Copy to E.{Mr Elliott - Chief Engineer} With reference to our own Shock Absorbers, I think it is necessary to increase the height of the filling hole, and possibly make it suitable really for fitting a syringe, so that the oil can be forced into them. It is very desirable, i.e. imperative, to keep the space quite full of oil. Now there is a small hole that allows a small quantity of oil to pass through the piston. This hole might commence at the very top of the piston on the high pressure side and discharge at the lowest position on the low pressure side. This may make it right while any oil was in the system, but to be safe the spring load valve passages should be arranged likewise. F.H.R. (Handwritten in left margin: X233) | ||
