| TO BY.{R.W. Bailey - Chief Engineer} FROM DA.{Bernard Day - Chassis Design} ORIGINAL DA{Bernard Day - Chassis Design}2/M20.3.26. Copy to - EH. HS.{Lord Ernest Hives - Chair} RR. HYDRAULIC SHOCK DAMPERS. X235 X8520 We send herewith N. scheme Z162. shewing R's suggested modification incorporating both high and low pressure valves in the piston, larger inlet valves, a cylindrical filter under the standpipe instead of a flat one, and a screwed gland. R.{Sir Henry Royce} has instructed us that the double valve scheme is to be regarded as a future modification, consequently is not part of the present urgent experiments. We suggest that you should wait for this until we get some comments from R.{Sir Henry Royce} We expect however that the screwed gland will most certainly be required on the first shock dampers, and we suggest you should incorporate this in your present experiments.
