B.III REAR SHOCK DAMPERS. The ride of B.III can be improved by having unequal leaks in the rear dampers on the bump and rebound strokes. As the system of unequal leaks leads to replenishment troubles, we want to get the difference of damper poundage by different valve areas for the two strokes. Will you please detail and instruct two pairs of valves one giving rebound and bump loads in the ratio 1 1/2 : 1 the other 2 : 1 Rm{William Robotham - Chief Engineer}/AFM.{Anthony F. Martindale} | ||
