Jenner}1/HP.24.12.36. Phantom III Ordinary Rockers. In connection with the scheme LeC.5441 for the above, we send you LeC.5444 showing the simplified oil pipes as described in memo E/JNR.{Charles L. Jenner}1/HP.22.12.36. If we can get away with the scheme of ordinary rocker operation there are further economies that can be made to the relief valve. We no longer need the non-return ball valve nor do we need the leak in the seat of the high pressure valve. LeC.5444 herewith. E/JNR.{Charles L. Jenner} | ||
