Abstract: A fluid pulse operated system provides selective output for operating a fluid device, such as reversing operation of a fluid motor, or memory device in a logic environment. The system includes a pair of chambers separated by a flexible diaphragm. Fluid paths, one through each of the chambers, each includes an inlet for pressurized fluid into the associated chamber and a chamber outlet connected with a normally closed vent valve. Output signal lines are provided in the paths, one between each of the outlets and the associated vent valve, for connection with the motor or providing memory signals. The diaphragm serves as a valve member which selectively cooperates with one of a pair of valve seats, one for each of the outlets, for closing the selected outlet. During normal operation of the system either of the outlets may be open and the other closed by the diaphragm which is releasably retained in its selected closed position by a differential in facial area of opposite sides of the diaphragm exposed to fluid in the respective chambers. In order to reverse the diaphragm, thereby opening the previously closed outlet and closing the formerly open outlet, the vent associated with the outlet to be closed is momentarily opened, thereby reducing the fluid pressure in the associated chamber and causing the diaphram to reverse its position and seat against the valve seat about the outlet to be closed. The system operates with little power while pulsing through a control cycle and stands by with no power in a static condition, by provision of positive fluid pressure, being decreased by control pulses and by provision of gating structures sealing off leakage paths in static condition.
