FLUID-CONTROLLED SELECTION SYSTEM

摘要

A fluid-controlled selection system having a number of logical fluid elements, each of which has a pressure output communicating with a pressure input. In the communication between a pressure input and a pressure output at least two series-arranged fluid interrupters are incorporated. The said fluid interrupters in each logical fluid element are controlled by means of control signals originating from a combination of two control pressure lines from a total number of control pressure lines for the entire selection system, this combination being different for each fluid element.
