| To DA.{Bernard Day - Chassis Design} BY.{R.W. Bailey - Chief Engineer} Hs.{Lord Ernest Hives - Chair} FROM R.{Sir Henry Royce} c. to CJ. BJ. 48520 RL/M19.3.26. RE. RR. HYDRAULIC SHOCK DAMPERS. N. sch. 2159. X.235 X.8520 (1) I like much better the filter cast on the body - i.e. not the separate standpipe. (2) I fear we must not trust to the air and oil pressure tightness of the gland, and I think the spring load one is hardly practical. This will soon prove itself in the design, or test. Perhaps the best is the screwed one. (3) The filter might be as sketch below. This seems simple and gets rid of some of the awkward features. SEE ORIGINAL FOR SKETCH.
