| E.{Mr Elliott - Chief Engineer} from Hs.{Lord Ernest Hives - Chair} X5060 Hs{Lord Ernest Hives - Chair}6/LG18.4.28. 20 HP. VALVE TAPPET AND ROCKER SHAFT LUBRICATION. X5202 With reference to the attached. We have been looking into the question of the new design of relief valve for the 20 HP. on the same lines as the present Phantom and find that this was only designed as a single stage unit. At the present time we should like it to be similar in design to the Phantom. Temporarily we are using a Phantom relief valve but we should like a design from you for the 20 HP. which we could standardise. Hs.{Lord Ernest Hives - Chair} | ||
