| HS.{Lord Ernest Hives - Chair} FROM DA.{Bernard Day - Chassis Design} ORIGINAL OIL PUMPS. RECEIVED 3 JUL 1931 DA{Bernard Day - Chassis Design}3/M2.7.31. 83449. Can you supply us with any information as to the pressure that a gear pump will supply. Will such a pump for instance maintain 100 lbs. per sq. in? The temperature would be that reached by the gearbox oil, and the oil not too thick, probably of the consistency of engine oil. If not 100 lbs. per sq. in., what is the maximum pressure we could expect it to maintain? DA.{Bernard Day - Chassis Design} | ||
