RMC. ------------------------ HDY. {William Hardy} 2/HP.25.9.33. ----------------- Damper Governor Control. ------------------------ We think that the spring on the pressure release valve may have a lower rating with advantage, than is now provided, and we send N. Sch. 3837 which shows what we suggest. We also think that a packing washer will be found useful to allow for variations in springs and bore of valve seat. A screwdriver slot should be tried in place of the internal square hole, to reduce expense here if possible. HDY. {William Hardy} | ||
