IPC: F15C3/00
Filed: 1971-05-13
Abstract: 1371235 Valves MARTONAIR Ltd 22 Feb 1972 [13 May 1971] 14747/71 Heading F2V [Also in Division G4]  A fluidic AND gate comprises a valve unit, Fig. 2, having a chamber containing a spring- loaded valve member with resilient peripheral lips. The chamber has two ports as shown. The upper port is selectively connected to a source of air under pressure, representing one inlet signal, or to exhaust. The lower port is connected to the outlet port of the gate and receives the other of the inlet signals. In the absence of an inlet signal at the upper port, a spring lifts the valve member from its seat and the signal at the lower port causes the lips to deflect upwards as shown so that the signal passes to exhaust. When a signal is present at the upper port the lips seal against the chamber wall to prevent communication between the ports so that the signal at the lower port passes to the outlet port, fulfilling the AND function. A multiple AND gate, having more than two inputs, has a number of such valve units, with individual inlet signals at their upper ports and a common inlet signal at their lower ports. When all the upper ports receive a signal the signal at the lower ports passes to a common outlet port.
