ABSTRACT:
The specification discloses an air logic circuit with two, five port valves connected between an air supply and a volume chamber for supplying an output signal at an output port when both valves are activated substantially simultaneously. When both valves are in a released condition there is no output signal and the air supply is connected through the serial combination of both valves to a volume chamber. When either of the two valves is activated alone, the volume chamber is coupled to the atmosphere through an exhaust orifice. When both valves are simultaneously activated, the volume chamber is coupled to an output through the serial combination of both valves.
