| E.{Mr Elliott - Chief Engineer} from Hs.{Lord Ernest Hives - Chair} ORIGINAL. SPRING CONTROL FOR BUTTERFLY VALVE X3436 This is the scheme suggested by R.{Sir Henry Royce} in order to avoid any stickiness in the baffle in the exhaust pipe holding open the main throttle. We understood that R.{Sir Henry Royce} was very keen to get this on the cars as soon as possible and as cars are now being received on test fitted with the exhaust heated throttle, we got the D.O. to get out the attached scheme. We should be pleased to have your comments. Hs.{Lord Ernest Hives - Chair} | ||
