| To Hs.{Lord Ernest Hives - Chair} from Da.{Bernard Day - Chassis Design} DA{Bernard Day - Chassis Design}4/M27.2.26. RE. R-R SHOCK DAMPERS. X.235 X.8520 With reference to your report Hs{Lord Ernest Hives - Chair}/Rml/LG25.2.26, we presume you will have tried a vent in the reservoir. It seems to us that this might be a means of reducing the quantity of oil that gets out. Presumably you will also have tried running the shock damper with the top cover off so as to see what is happening inside, because it seems strange that when the oil is at as low a level as is represented by the loss of a third of the quantity, it should still work out. In the meanwhile we are working at a modification to the gland in the hope of improving this, though we are afraid if there is some powerful tendency for the oil to come out that we shall not be able to check it by means of a gland. Could you temporarily fix up a means of trapping the oil as it comes out and returning it to the reservoir as indicated in sketch below? DA.{Bernard Day - Chassis Design} SEE ORIGINAL FOR SKETCH: | ||
