Abstract
An improved pneumatic control system is selectively deactuable and actuable for controlling movement of the armature of a pneumatically-operated device between first and second working positions and includes a timing subsystem that enhances the efficiency of the overall system by stabilizing the control system at a pressure necessary to maintain certain static conditions in the pneumatically-operated device, while still providing for full control air pressure when dynamic operations are required. In addition, such a control system compensates for system leakage in an efficient manner by using full control air pressure only when needed for proper operating functions of the overall system.
