We send you herewith:- LeC.5352 showing a pot for the oil pressure filter. This consists of making the pot deeper, and larger at the bottom to allow for accumulation of sludge, which will not be disturbed by the in-flow of oil. This experiment should be tried without the coarse additional gauze to LeC.5342, but we should retain the bypass spring of increased pressure to lift it 20 lbs/sq.in. as shown on LeC.5338. E/JNR.{Charles L. Jenner} LeC.5352 herewith. | ||
