| contd :- -2- The tests were conducted as on the Rolls-Royce shock absorbers by means of maximum pressure reading gauges and the point at which the valves lifted was determined by means of the Chronograph. Summarising our opinion of the latest Lovejoy we should say that while they can give soft riding and yet an appreciable amount of damping for axle movements of large amplitude, their action is not sufficiently positive to prevent pitching or to give the car control demanded by the average British owner driver. We do not believe that a single acting damper can ever give the optimum results nor that a damper which is not 'forced fed' will ever prevent passengers being thrown to the roof on bad Continental roads. We believe that the American complaint of pitching will be largely overcome by the adoption of the R.R. hydraulics at the rear. Hs{Lord Ernest Hives - Chair}/Rm{William Robotham - Chief Engineer} | ||
