| RG.{Mr Rowledge}) FROM R.{Sir Henry Royce} HS.{Lord Ernest Hives - Chair}) Copy to BL ORIGINAL R5/M14.5.28. OVEROILING. X2176 Y3933 We think it is quite a good idea to have the oil pressure varying with speed. The question is how should it be done, and really do it. Several ideas occur to one. For instance the valve might be lifted by some means when the throttle is closed, such as by the induction pipe vacuum. R.{Sir Henry Royce} | ||
