Your Ref: Hs{Lord Ernest Hives - Chair}/Gyl/LG. 15th April, 1929 Messrs Rolls-Royce Ltd., DERBY. Dear Sirs, We thank you for your letter of the 10th. At the time of writing, we have not heard from your Production Department regarding the testing of meter valves. The rates of flow of the meter valves will be as follows when tested with Luvax oil at 70° F.{Mr Friese} and at a constant pressure of 100 lbs. per sq. inch:- No.00 .02cc per minute No.0 .06cc " " No.1 .17cc " " No.2 .30cc " " No.3 .50cc " " All these rates of flow are subject to a tolerance of plus or minus 20%. With reference to the second and third paragraphs of your letter, we may say we have been carrying out considerable experimental work with a view to obtaining the most accurate production methods. We have found that reaming the central hole in position is not satisfactory in production for two reasons; the first being that if the filter end of the cartridge is fitted before being pressed into the stud, difficulty is experienced in thoroughly cleaning out the hole after reaming. Alternatively, if the cartridge is pressed in and reamed before the filter end is assembled, difficulty is encountered in assembling the filter end, particularly in the double meter valve where the distance from the end of the stud to the end of the cartridge is approximately 21/32". However, we are Contd: | ||
