ABSTRACT:
A fluid operated control device which co-operates with reciprocating means, such as a pneumatically driven shaft. The device includes a main cylinder and piston backed at each end by valves which each include auxiliary cylinders and pistons. The valves provide signal inlets and outlets which can be cross connected to cause continuous reciprocation of the main piston. Alternatively, the valves are operated to displace the main piston selectively or are connected to a delay to vary the timing sequence. Stroke adjustment is possible by a rod attached to one of the auxiliary valves. The main piston is mounted on a shaft passing through the other auxiliary valves.
