Smith}' AXLE CONTROL DAMPER TO H.SCH. 2635 From our tests so far there does not seem to be any difficulty in making this damper work. We find that we can only have one air vent, that over the high pressure valve. This is because we only replenish on the upward stroke of the piston, therefore if we have an air vent on the downward stroke we get lost motion. Hs{Lord Ernest Hives - Chair}/Bn.{W.O.
