| TO RY. FROM DA.{Bernard Day - Chassis Design} Copy to CJ. HS.{Lord Ernest Hives - Chair} ORIGINAL DA{Bernard Day - Chassis Design}3/M4.3.26. √235 / x8520 RR. HYDRAULIC SHOCK DAMPERS. We send herewith N. scheme 2153. This shews some suggestions which we have sent to R.{Sir Henry Royce} for the object of reducing the leakage of oil through the rocker shaft. We have also included on the drawing some of R's most recent suggestions - (1) Improved escape for the air from the high pressure valve chamber. (2) Improved filter in the bottom of the reservoir. The suggestions for lengthening the rocker arm and reducing the bore of the shock damper will have to be approved by R.{Sir Henry Royce}, and we suggest that you should not do any-thing with this, but should take off N. scheme 2153. all the points except these proportions, and apply them to the existing shock damper. R's other suggestions regarding the filter, method of filling, etc, we shall send you on another draw-ing immediately. DA.{Bernard Day - Chassis Design} | ||
