<p>824,150. Maintaining vehicle height constant. FORD MOTOR CO. Ltd. Jan. 3, 1958 [Jan. 3, 1957], No. 338/58. Class 108(2) Valves 44, 53 controlling respectively supply and exhaust of air from suspension springs (not shown) are supplemented by a minimum pressure exhaust relief valve 52. The latter thus limits the degree to which air can escape from the springs even though the valve 53 may be held open. The valves 44, 53, are controlled by the height of the vehicle acting through a lever 59. In a modification (Fig. 1, not shown), the valve 52 may be external to the housing of the valves 44, 53.</p> |
