| -2- Rm {William Robotham - Chief Engineer} /Les.4/WH.30.10.37. When going over the cost figures of our present damper there is very little economy that can be made without major design alterations. A new design is badly needed even if we continued with the single cylinder damper, but we do not think we are justified in designing and developing a new damper for economy if we do not also produce a damper which will be more satisfactory to customers. We recommend that if a new design of damper is required we change to the twin cylinder damper. There are two main types of twin cylinder dampers - (a) The Armstrong which has the piston connected by links to the intermediate lever. (b) The Vauxhall front suspension damper which has the pistons spring loaded by line contact against the lever. Rm {William Robotham - Chief Engineer} /Les. | ||
