Abstract

The device performs logical functions which are represented by suction signals. This is achieved by mixing jets emerging from nozzles with parallel axes. Two turbulently interacting jets create between them a zone of decreased pressure in comparison with the ambient pressure level.

Fluid Logic Suction Control

The device performs logical functions which are represented by suction signals. This is achieved by mixing jets emerging from nozzles with parallel axes. Two turbulently interacting jets create between them a zone of decreased pressure in comparison with the ambient pressure level.

In this And, binary information is represented by the presence or absence of jets A and B. When both are present, a suction signal :AB occurs in the center channel. It is used to control a fluid amplifier sensitive to suction control signals.

Other logical functions are performed when jets A and B, instead of interacting with each other, interact with a steady flow. For example, five nozzles can be situated side by side; A channel, upper suction channel, steady flow channel, lower suction channel, B channel. A low pressure is developed in the upper suction channel in the presence of jet A, and in the lower suction channel in the presence of jet B. The suction channels are used as control channels to a fluid amplifier. An Or function is performed if a signal in either or both suction channels deflects the power jet of the fluid amplifier.
