Abstract

1372569 Fluid logic and switching circuits MAGYAR TUDOMANYOS AKADEMIA AUTOMATIZALASI KUTATO INTEZET 18 Nov 1971 [20 Nov 1970] 53624/71 Heading F1P The control input line L i of a group of fluidic elements R o , which, having been switched to a stable position are no longer in need of a control pressure, is connected through an on-off fluidic switch S to a control pressure source P t ; switch S being controlled by manual or automatic means D, e.g. a fluidic switch having a supply inlet connected to the control pressure source P t , a control inlet connected to the signal inlet line to elements R o and its outlet connected to the control inlet of switch S which thus remains closed until a signal appears at R o for processing thereby. The system shown includes a further group of elements R 1 of which elements MT 1 require continuous full control pressure to maintain them in this stable position and of which elements MT k require a reduced continuous control pressure.
