| To BY.{R.W. Bailey - Chief Engineer} from E.{Mr Elliott - Chief Engineer} c. to BJ. Hs.{Lord Ernest Hives - Chair} X 8205 E2/M26.6.26. PHANTOM OIL RELIEF VALVE. X.7205 X.8205 We send herewith LeC.2257 shewing a revision of the previous scheme made so that the new unit can be adapted to the existing crankchamber. When Mr. Hancock was down here recently he informed us that he thought there was insufficient relief valve areawith the experimental unit on 12-EX. Mr. Royce would like you to make a test to determine what variations in high and low pressure you experience, to decide whether any alteration should be made. E.{Mr Elliott - Chief Engineer} | ||
