ABSTRACT:
This invention relates to a pneumatic cylinder and valve control system in which a block and two plates bolted to the block form one end of the cylinder. This block and plate combination, moreover, provides the housing for the valves and conduits that comprise the pneumatic control system for the operation of the cylinder. To produce greater force, moreover, two pistons mounted within the cylinder on the same line of action both are in fluid communication with the pneumatic control system.
