Letter concerning oil pressure requirements for a thermostat and oil valve equipment.
| Identifier | ExFiles\Box 39\4\ Scan255 | |
| Date | 7th April 1932 guessed | |
| -2- The pressure of oil here is rather an important matter owing to the fact that the Thermostat is required to lift against the pressure within the chamber, and in addition, to exert a force on the oil valve equipment of 3½ lbs per sq.in. With regard to the last paragraph of your letter, we should be much obliged of you would look into our proposed arrangements before the writer visits you to discuss this matter. Yours faithfully, p.p. S.Smith & Sons (Motor Accessories) Ltd., (sgd)F.G.Efford. Midland Engineer. CWN. | ||
