ABSTRACT:
A pneumatic control for cyclic successive activation of a plurality of pressure fluid consumers and comprising a series of control modules abutting each other in side by side relation for controlling activation of respective ones of the consumers. Each control module comprises a logic plate containing an AND gate and an OR gate and supporting a bistable impulse valve. Each control module further includes a connection plate having connecting openings in its front and rear sides for communication between adjacent modules and means for connecting to the associated consumer. An intermediate seal plate interposed between the connection plate and logic plate has channels therethrough connecting the gates and bistable valve on the logic plate with the connecting openings and connecting means in the connection plate in a manner determined by the pattern of such channels in such intermediate seal plate. The end, or last, control module in the series has an intermediate seal plate differing in the arrangement of its connecting channels from the intermediate seal plates of the preceding control modules to assist in starting a new operating cycle of the plurality of control modules and their associated consumers.
