Abstract

The fluidic logic AND-OR gate comprises a shuttle (6) free to move between two seats under the action of a membrane (3) which is subject to a pilot pressure (A). The sectional area of the membrane is greater than the section of a first disc valve (4) which has a greater section than a second disc (5). The disc rests on a seat (6a). An air passage bored into the shuttle (6) connects the discharge (5) with the exhaust (E) through a hole (6b) only when the pilot pressure (A) is zero.
